Following the tutorial, look around, then take the scroll from the guard. Examine the scroll, sliding off the ribbon and unrolling it. Back out, then examine the door on the left. Examine the door bell on the right and rotate the top part to the right. Next rotate the bottom part to the left until the side arms drop down. Pull the chain on the left to ring the bell, then pick up the small metal object that falls out. Examine the mailbox beneath the door bell. Spin the lid on the top and take the key part, then combine this with your small metal object (slide them together and rotate). Examining the mailbox again, slide the small cover on the front towards the left, then insert the key into the keyhole. Turn the key, open the mailbox and take the Oculi Infinitum.
Use your Oculi Infinitum while looking at the door, then rotate the 3 discs so their openings point towards the middle. After the explosion, head inside and through the door at the top of the stairs.
Turn right and look at the bookcases along the wall. Zoom in on the left bookcase (number 1), and find the drawing in the right of the shelf here Printing Press.
Back out and look at the scroll on the lamp post in the middle of the room. Slide the scroll seal off to the right, then read the scroll. Examine the seal in your inventory and rotate the middle section to align the arrows, forming a three-spoked seal. Zoom in on the green pedestal below the box on the left side of the room. Slide the cover to the right, then use the three-spoked seal on the mechanism that is revealed. Rotate the seal so the arrow points down, then press the opened eyes on the bust and open the helmet to see inside. In this puzzle, you need to move the large colored stones between the smaller stones of the same color. Now pull open the drawer and take out the glove (on which you mount the Oculi Infinitum).
Look back at the opened helmet and use the Oculi Infinitum. Drag the left gear down and rotate it clockwise, then drag the right gear down and rotate it anticlockwise. Take out the fine wooden ornament, which is in the shape of a rose. Also take the piece of wire from here.
Back out, then examine the ivory case below the bust. Use the Oculi Infinitum, then focus on the past of the case with the X mark. Slide this to the side, then use the piece of wire on the opening. Rotate this, then pull open the drawer and take the part of wooden ornament.
Back out again, then focus on the left corner of the green pedestal. Drag your part of wooden ornament here, then slide the 3 pieces together to create a flower. Rotate the device that appears, and take out the brass screw. Examine the rose wooden ornament in your inventory and add the brass screw into the back, then rotate this to complete the wooden rose. Go back to the lamp post and insert the wooden rose just above the scroll. After the side panels open, drag the rose up on the first panel, then down on the second (sliding as needed), up on the third (rotating as needed) and down on the fourth (sliding and rotating as needed). You can use the Oculi Infinitum for help if you need it. Take out the small key when you are done. Look at the top of the ivory case and insert the small key, then turn it. Take out the richly-ornamented seal from the top.
Examine the seal in your inventory and pull the handle upwards to adjust it. Back out and look at the top of the lamp in the middle of the room, inserting the adjusted seal here. Rotate this clockwise until you can see a light beam coming out from its base. Rotate the scene so this is coming straight down, then rotate the small prisms to guide the light beam around in this order:
Go over to the bookcase that is lit up by the spotlight from the lamp, and take out the book with a leather cover. Examine this in your inventory and look at the spine. Rotate the ends down, then slide down the middle portion and press the button that is revealed. Read the letter, then take the Oculi Tempus. Use the Oculi Tempus and go to the glowing area in the corner of the room. Trace the shape, then watch the time-line. Zoom in on the wall panel and press it. Push open the bookcase and go through.
Read the letter on the table. Look at the top of the siege tower and rotate the soldiers on the top until a third one appears. Take the wooden wheel from the third soldier Spin the other two wheels completely to raise two flags and open part of the siege tower. Attach the wooden wheel to the wooden shaft and turn it to open the catapult arm. Open the small compartment on the corner and take the small metal part, then press the trigger to fire the catapult and light a lamp further into the room.
Go over towards the lamp. Turn left and look at the set of shelves to find another drawing File-cutter. Back out and turn right, then focus on the top of the large globe. Spin the middle part to match the pattern with the bottom part, then spin the top part to continue the pattern. Flip open the top and take out the metal sun. Examine this in your inventory - look at the back and attach your other small metal part, then rotate it to create a sun-shaped key.
Look at the middle of the large globe and move aside the 2 halves of the cover. There are now three layers of disc here - you need to rotate them so the central holes are all aligned, then you can insert the sun-shaped key and rotate it. Pull open the halves of the outer shell of the globe to reveal a complex-looking surface with two lenses.
Back out from the globe for now and look at the smaller desk in the background. Open the scroll here to read it. Now focus on the crumpled piece of paper to the left. Use your Oculi Tempus - trace the shape, then drag the time-line back to straighten out the paper and see 4 words: TERRA, LAPIS, SIDUS, IGNIS. Back out and slide the left inkwell to the left, then find a small catch next to this inkwell and slide it back to the right. Focusing on the central part of the desk, drag the 4 panels out to the corners to reveal an 8-pointed star. Back out and look at the central pillar beneath the desk, sliding up the small panel, then take out the unusual key. Examine this and tilt the disc at the top to adjust it.
Go back to the globe again and look at the left disc with the Oculi Infinitum, then enter the code TERRA. Repeat this with the next disc near the bottom (opening the iris first), then use the Oculi Infinitum and enter the code LAPIS. Repeat this with the next disc near the top (opening the iris first), then use the Oculi Infinitum and enter the code SIDUS. Look at the final disc. Slide the flower ornament up and it will come off. Insert it on the edge of the disc and drag it around to open the iris, then use the Oculi Infinitum and enter the code IGNIS. Zoom in near the top of the globe and insert the adjusted unusual key. Rotate the key and it will slide down and open up the globe.
Further open the globe, the read the message about your next challenge. You need to gradually conquer all of Europe. Start by making these moves:
- 31 > 14
- 45 > 29
- 48 > 32
- 48 > 19
- 67 > 38
- 87 > 77
When the new towers appear, take out the wooden tool with ornament. Go back to the 8-pointed star in the desk and put this wooden tool in the middle. Spin the tool, then pull out the 8 points from the star. Zoom in on the raised section and take the model tower. Go back to the opened globe and put the tower in the empty space. Now you can continue with more moves on the strategic map:
- 36 > 20
- 48 > 28
- 60 > 30
- 88 > 47
- 121 > 58
After the remaining towers appear, read the new message, then make the final moves:
- 175 > 100
- 221 > 123
- 288 > 46
- 330 > 143
- 459 > 34
- 491 > 300
- 565 > 55
- 616 > 779
- 779 > 512
- 799 > 790
Open the iris, then look at it with the Oculi Infinitum. Rotate the central wheel first, then both corners so the drawer drops down. Now pull out the drawer so you can retrieve the small shield. Back out from the globe and go back to the siege tower. Look at the front of it to see a small shield, and insert your new shield on the adjacent side. Pull open the covers and grab the metal key from the right. Slide the 2 brass pieces so you can remove the curved engraved crank.
Back out and look at the additional wheel on the right side. Insert the metal key and turn it clockwise, then take the blue crystal. Now look at the round puzzle next to the siege tower. Put the blue crystal into the bottom segment. Now you need to solve a Towers of Hanoi puzzle. The goal is to get the tiles to the middle stack, and this is the shortest method:
- Left to middle, left to right, middle to right
- Left to middle, right to left, right to middle, left to middle
- Left to right, middle to right, middle to left, right to left, middle to right, left to middle, left to right, middle to right
- Left to middle, right to left, right to middle, left to middle, right to left, middle to right, middle to left, right to left, right to middle, left to middle, left to right, middle to right, left to middle, right to left, right to middle, left to middle
Insert your engraved crank in the hole that has been revealed. Use your Oculi Infinitum and turn the crank to line up the images on the right. Turn the small wheel at the back of the siege tower, then use the trigger again to light another flame in the distance. Go over to the blue curtain near the new flame and pull the cord to reveal a tall wooden cabinet. Look in the bottom and pick up the tetrahedron.
Look up to the top of the cabinet and insert the tetrahedron into the triangular hole, then pull open the panel and a puzzle will be revealed below. Back out again and focus on the panel you pulled open, grabbing the disc with grooves. Go down to the puzzle below and insert the disc with grooves here. Use this to rearrange the 4 numbered pieces to match the adjacent numbers. Now take the hexahedron.
Look up to the top of the cabinet and insert the hexahedron into the square hole, then pull open the panel and a puzzle will be revealed below. Back out again and focus just beneath the panel you pulled open, pressing the button in the middle of the rose. Look up to the open panel above, grabbing the disc with a long groove. Go down to the puzzle below and insert the disc with a long groove here. Use this to rearrange the 4 numbered pieces to match the adjacent numbers. Slide out the small wooden catches, rotate the container, then take the three-piece object with a threaded rod. Examine this in your inventory and rotate the ends to create a sphere.
Look up to the top of the cabinet and insert the sphere into the round hole, then pull open the panel and the figure will slide down halfway on the panel below. Rotate the figure, then pull open the panel. Zoom in on the disc here and rotate the part circles, then take out the metal disc with one groove. Go down to the puzzle below and insert the disc with one groove here. Use this to rearrange the 4 numbered pieces to match the adjacent numbers. Rotate the wooden cover, then slide the metal cover to the right, so you can take the special geometric object. Examine this in your inventory and move the two small switches, then flip the end pieces to create a dodecahedron.
Look up to the top of the cabinet to see that the hexagonal hole is blocked by bars. Look down to the rose below and press the small button above it - this will remove the bars. Now you can insert the dodecahedron into the hexagonal hole, then pull open the panel and a puzzle will be revealed below. Rotate the 4 corner figures around the rectangle here. Spin around to see the golden drawer on the other side of the cabinet at the same level. Pull the drawer open and take out the wrench with a cross head. Look at the cross directly above this drawer and attach the wrench, then rotate it anticlockwise until it comes off again. Pull open the cabinet and take the engraved geometric object. Examine this in your inventory and rotate the central part, then push in the end pieces to create an octahedron.
Look up to the top of the cabinet and insert the octahedron into the diamond hole, then pull open the panel. Take the metal ram's head and the large gear.
Go back to the front of the siege tower and attach the ram to the wooden beam near the bottom. Rotate this clockwise until the mechanism further opens, then take the engraved metal handle.
Return to the cabinet and look at the mechanism near the top. Insert the engraved metal handle and rotate it clockwise. to reveal a golden castle. Rotate the disc beneath the castle and take out the small key. Insert this into the keyhole above the castle and turn it, then 2 of the spires on the front will move out to the sides. Use the Oculi Tempus while looking at the castle. Trace the shape, then watch the time-line. Rotate the spires into the positions nearest the end of the time-line, and the roof will slide forward. Pull it further forward until it rotates down.
Zoom in to the slot near the the back and slide the latch to the left. Push the rod down that appears. Focus on the opposite tower that has opened. Rotate the device inside, then take out the folding knife. Examine this in your inventory and open it to reveal a knife. Back out and rotate around to the other side of the castle. Use your knife on the knotted rope and cut through it. Shake loose the remaining piece of rope, then open this side of the castle. Insert your large gear.
As the front discs on the castle rotate, you need to click on each of them to stop them at the correct time; you will then automatically take out the silver dove crank. Use this on the opening just above, then rotate it clockwise to gradually reveal a hexagonal metal block from the top of the castle. Remove this, then examine it in your inventory. Rotate the bottom part to expand the block vertically. Slide the latch near the top upwards, and you will be left with a hexagonal weight.
Back all the way out to the siege tower. Look slightly right, and approach the wooden screen to the right of the large flame. Look at the stone pillar immediately to the right to see an opening. Insert your hexagonal weight here and the wooden screen will open. Go through the curtains ahead, then use your Oculi Infinitum. Look slightly left and take the forged metal ornament. Back all the way out to the siege tower and look at the right side. Insert the forged metal ornament here, which is an aiming device. Use the Oculi Infinitum again and look to the right to see your target in the distance. Use the crank to the right to rotate the siege tower to the right. Look through the aiming device to make sure you are aimed at the glowing target. Turn the small wheel at the back of the siege tower, then use the trigger again to light another flame.
Go through the curtains to find a new lit area. Use the Oculi Infinitum to see some blue glowing outlines. Turn the large wheels on the sides to move the statues in line with these glowing outlines (by dragging the slider in the distance you adjust the amounts the statues on each side move relative to each other). Once correct, another set of doors will open and you will proceed through.
Look at the pedestal and read the letter here. Use the Oculi Tempus and trace the shape, then adjust the time-line until you see a glowing sketch. Rotate the discs until you recreate the drawing of the Vitruvian Man. Rotate the component of the base of the goblet that appears, then slide out the largest parts of the base. Remove the goblet, and the pedestal will close, then a secret passage will appear. Look at the torch on the left wall. Release the catch to light the torch, then take it to go down the stairs.
Examine the door, then the statue to the left, which is holding a large scythe. Take the metal tool from between the statue's hands. Now click on the 2 metal plates that were being held by the metal tool, and you will end up with a scythe handle. Examine this in your inventory, and rotate the top until it turns into a completed handle.
Back out and examine the large disc in the door. Rotate the ring so the hole is at the very bottom, then use your completed handle here. Rotate this clockwise to lower a panel, then take the wooden shaft. Back out and look near the bottom of the door. Drag two corners down, then smaller wooden pieces out, so you can take a foldable wooden handle. Examine this in your inventory. Use your metal tool on it, then fold it closed to create a screwdriver.
Next examine the top of the scythe, and use your screwdriver on it, then rotate the screwdriver anticlockwise. After the blade drops down, take out the strange key that is revealed. Examine this in your inventory. Drag both bits of the key down to the bottom to create a small completed key. Now look over at the top of the hourglass held by the statue on the right. Insert the key and turn it clockwise. Open the hourglass and take out the cylinder. Use the Oculi Infinitum while looking at this statue's other hand to see MORS written on it. Look at the base of the left statue and insert the cylinder here, then rotate its letters so the whole message is NOMEN ILLI MORS.
After the statue changes, you will be looking at the base again. Press the 2 diamond-shaped buttons and take the lever. Now focus on the statue's skull. Pull open the jaw and take out the ornamental handle. Pay attention to the symbols on the skull's forehead, then back out. Look at the step at the base of the door and press three of the buttons in this order:
Use the ornamental handle on the top gear of the device that is revealed, then turn it clockwise. Pull open both hatches. Insert your wooden shaft on the right of the mechanism, then close both covers over its end. Insert your lever on top of the wheel at the back of the mechanism. Once the drawer on the right opens, take out the large ornamental disc. Insert the ornamental disc into the hole in the main door, then look at it through your Oculi Infinitum. You need to rotate the outer ring and the smaller individual circles so that there are three pairs of matching symbols on the inner part of the disc. After the door opens, head inside.
Take the sword from the suit of armor. Back out and turn left, entering the next room. Examine the large sarcophagus, and zoom in on a narrow hole near the left. Insert the sword here, then rotate it anticlockwise so that a small wooden box appears. Focus on some small scratches near the bottom of the right side of this box, and turn the small piece of metal here so that a compartment slides out. Pull this drawer out further, and pick up a spring mechanism. Examine the drawer more closely, and drag one partition to the right, then another down, and take the small cross-shaped item that is revealed.
Rotate around to the left side of the wooden box, and focus on some more scratches near the middle. Rotate the metal latch here to reveal a small hole. Insert your small cross-shaped item and turn it anticlockwise, then take the folding key that appears above. Examine this in your inventory and open it so it becomes and unfolded key.
Rotate back around to the right side of the wooden box, and focus on the middle. Turn the cover and insert your unfolded key. Turn the key anticlockwise, then open the main cover of the box and grab the metal wolf's head. Now look at the sliding puzzle in the top of the box:
Slide the pieces from these positions to solve the puzzle: 2, 5, 4, 7, 8, 9, 6, 5, 8, 7. Take out the strange metal tool. Examine this in your inventory and pull the sides up to create a metal tool with arms. Notice the fireplace to the left, and zoom in on the bottom-left corner of the painting above it. Slide the corner of the frame to the left, then look down on it and take part of a mechanism. Back out 3 times to return to the sarcophagus.
Now focus on the 3 holes where a wolf's head is missing, and attach the one from your inventory. Slide this to the left, then examine the recess that is revealed. Insert the part of a mechanism your found in the picture frame, then pull it down and take out the cogwheel. Beneath here, rotate the disc to the right, and slide up the shaft beneath this. Take a strangely-shaped object from the recess that is revealed. Examine this in your inventory, and rotate the disc until it transforms into a brass cross.
Go all the way back out to the suit of armor again. Examine the breastplate and insert your metal tool with arms, then turn it so the suit opens. Pick up the wooden base with a flint and steel. Examine this in your inventory, and insert your spring mechanism. Rotate the disc at the top, then push the trigger mechanism inwards to create a spring-powered lighter.
Back out and turn left, then go through to the fireplace again. Look at the bottom of the fireplace and attach your cogwheel, then rotate it anticlockwise to lower a pair of latches. Back out and look at the left of the fireplace grate. Lift the latch, then pull the gate open. Look into the fireplace, and focus on the small metal fixture on the right. Lift up the small latch on the left, then lift the main lid. Insert your spring-powered lighter, then close the lid again. Drag the straw closer to the lighter, then pull the lighter's trigger until the fire is lit.
Look in the small hatch just above the fire and take the small wooden wheel. Examine this in your inventory and rotate both the top and bottom halves to end up with a wooden pulley. Look into the fireplace and retrieve your spring-powered lighter from inside the metal fixture. Turn around and look at the shelves of skulls on the wall behind you. Take the drawing from this shelf Viola Organista.
Go back out to the suit of armor and insert the pulley in the chest. Now lift the latch just to the left, and the knight will stand up. Press the button on the armrest, then take the lever with a triangular shaft that comes up from the middle of the seat. Slide forward the leg armor to reveal a strange three-pronged keyhole.
Back away from the suit of armor, then enter the next room and turn right. Walk towards the large wooden doors, then turn left and approach a small wooden cabinet with 3 panels. Insert your lever with a triangular shaft into the left panel, then pull it upwards - this will raise the left cage over the sarcophagus.
Look at the left side of the sarcophagus more closely, and use your Oculi Infinitum. Turn the wheel to move one of the screws into position to complete the glowing circuit. Pull the lever down and repeat this, until the circuit is complete. Stop using the Oculi Infinitum, and drag the knob all the way around the circuit to the far right - a small tower will rise up from the top of the sarcophagus. Examine this tower and insert your brass cross in the top of it. Open the tower further and take out the brass cylinder. Examine this in your inventory and pull it completely open to reveal a lever with an octagonal shaft. Look back at the inside of the door of the small tower. Slide the switch at the top to reveal another opening, then focus on the mechanism inside here. Slide the latch around the knob free. Close this inner compartment, then take the cogwheel on an axle.
Back away from the sarcophagus again. Walk towards the large wooden doors, then turn left and approach the small wooden cabinet with 3 panels again. Insert your lever with an octagonal shaft into the middle panel, then pull it upwards - this will raise the right cage over the sarcophagus.
Look at the top right of the sarcophagus. Spin the 4 outer discs, then spin the large middle disc, and another small tower will rise up here. Look more closely at this and rotate it to see some numbers. Use your Oculi Infinitum for a hint about another number in the sequence. Set the numbers to the Fibonacci sequence from bottom to top (I, II, III, V, VIII, XIII). Pull open the bottom segment of the tower and take out part of Da Vinci's model. Focus on the top of the tower and insert this part. Pick up the hexagonal metal object that is revealed. Examine this in your inventory and twist the handle to turn it into a star-shaped medallion. Insert this into the back of the tower, then slide it down. Open the tower fully and take out the wooden cylinder. Examine this in your inventory - slide the latch, then fold the arm until you create a crank. Use this on the hexagonal hole on the top of the sarcophagus next to the tower, and turn it until you can't turn it any more.
Focus on the wooden cube that has now appeared here. You need to drag the letters around to these positions:
After the inner mechanism rotates, insert your cogwheel on an axle into the blank space. Focus on the top of the panel that you can now see, and turn both circular latches, then pull down the next two latches. Take the four-tipped medallion from the inside of the opened door, and take the empty flask from the main compartment. Look in the bottom of the main compartment and slide a panel to the right to reveal a puzzle. Slide the 5 pieces to the center.
Now look at the right side of the sarcophagus. Turn the right circular mechanism so the opening is at the bottom, and a panel below will slide away. Slide the cover at the top to the right, then repeat this with the left circular mechanism. In the maze that is revealed, you need to move the 3 shields into the correct holders, and slide them to the end of the paths:
- Triangle Shield: Left holder
- Diamond Shield: Bottom holder
- Hexagon Shield: Top holder
Take the metal cylinder with rings. Back out and approach the desk along the wall (to the left of the fireplace). Read the letter, then focus on the middle panel of the small cabinet. Insert your four-tipped medallion here. Now you need to rotate the four discs so they are surrounded by matching colors. From the starting position, rotate these discs in a clockwise direction:
- Yellow 90°
- Red 180°
- Blue 270°
- Yellow 90°
- Blue 180°
- Green 270°
- Blue 180°
- Yellow 90°
- Blue 270°
- Yellow 270°
Look inside the opened left drawer and pick up the valve mechanism. Read the crumpled note, then slide the small slider inside the drawer. Now look inside the opened right drawer and pick up the weight-shaped tool. Back out and look at the end of the tube with flowing fluid - attach your empty flask here, then push it backwards until an opening is revealed above. Insert your valve mechanism here. Use your Oculi Tempus - trace the shape, then drag the time-line until you see liquid flowing. Now adjust the 3 handles on your valve mechanism to match those in the vision.
After the flask is filled, move it to the bottom of the machine to the right. Now use the pump handle above the flask until the door to the right is fully opened. Lift up the small latch on the left, then lift the main lid. Insert your spring-powered lighter, then close the lid again. Pull the lighter's trigger. After the top of the machine rises, take out the ornamental head.
In your inventory, examine the metal cylinder with rings, and attach your ornamental head. Push the head in to create a lever with a square shaft. Back away from the desk. Walk towards the large wooden doors, then turn left and approach the small wooden cabinet with 3 panels again. Insert your lever with a square shaft into the right panel, then pull it upwards - this will raise the middle cage over the sarcophagus.
Press the button on the top of the sarcophagus, then quickly take the roof of the model from the small compartment that opens on the corner - if you are not fast enough, press the button and try again. Also press the button from where you found the roof, and a large palace will rise up from the sarcophagus.
Back out for now and return to the standing knight. Look at the top of its helmet to see a depression with four points sticking out from a middle circle. Examine the weight-shaped tool in your inventory. One of the 6 points is fixed out. Working anticlockwise, pull out the next one, then leave one in, pull one out, leave one in, and pull one out - there should now be 4 points sticking out. Use the weight-shaped tool in this configuration in the top of the helmet, then rotate it to reveal the knight's face. Spin all 3 face segments around to see a series of 3 segmented cylinders. Use your Oculi Infinitum to see glowing markings on the cylinders, and rotate the segments to create a completed star. Take the special key. Insert this key into the leg where you moved the armor earlier. Rotate the key, then take the large lens on a long shaft. Examine this in your inventory and drag the bottom up to create a large lens on a tripod.
Go back to the fireplace and put this tripod in front of the fire. Rotate this until you see a focused light beam, and point this towards the palace on top of the sarcophagus.
Go over to the palace and look at the right side. Slide the stairs at the bottom to the left, and the top of the model will rise further. Look at the front of the palace near the top, and zoom in on the top middle ornament. Rotate this around, then pull the catch downwards to open a compartment. Take out the model of a staircase. Rotate around to the right staircase again and attach your new model, then slide it down. Open the small door beneath the stairs and take the medallion.
Back out and look at the top of this side of the palace. Insert your medallion on the left. Rotate all 3 discs, then drag the rope symbol to the far right. Rotate around to the back of the palace to see the next puzzle:
From this starting position, you need to move the red piece to the very top. Here is one solution (move all pieces as far as they can go):
- Move C up
- Move E right
- Move A left
- Move B left
- Move G up
- Move D left
- Move B right
- Move F up
- Move H left
- Move F down
- Move B left
- Move E left
- Move C down
- Move E right
- Move G down
- Move A right
- Move B right
- Move F up
Take the scepter-like object, then move the slider behind it to the left. Grab the part of the tower from the new opened segment. Look at this in your inventory, and add the roof of the tower to it. Rotate the roof until you have a completed tower model. Insert this into the corner of the palace where a tower is missing, and rotate it until it sticks. After the palace adjusts, look at the back of it where the light beam aims at a holder. Examine the scepter-like object in your inventory; slide the small latch up, then open the sides to reveal a lens on a long shaft. Place this in the holder, then drag the holder down, and the lens will catch the light beam. Rotate the holder to the left, and the light will be directed around the mirrors on the corners of the palace.
Look at the left side of the palace, where there are 6 small shields. If these are numbered 1-6 from left to right, press them in this order, discovered by trial-and-error: 5, 6, 4, 1, 2, 3. Once the high tower rises up, turn the top, and pull open the next segment. Turn the wheel inside here, then pull open the next segment. Take the wooden handle from inside, then drag a small metal knob down twice, and a compartment below will open. Pull this open further, and pick up the strange lock mechanism. Read the folded letter here, then back out from the sarcophagus.
Turn left and approach the device with large gears, which is further left from the desk. Look more closely at the small wooden box on the wall here, and insert your strange lock mechanism. Rotate the 3 dials on the right to create 3 matching lines on the left (the red should start in the middle and end at the top). After the cannon ball rolls down, insert your wooden handle into the large gear, then turn the gear clockwise until it stops. Go through the opened doors.
Go around to the large wooden table and pick up the cube. Examine this in your inventory and pull out the segments as they become free, until you can take a small metal key from the top. Read the crumpled note on the table. Next look at the puzzle board standing in the nearby corner of the room. You need to drag the green emerald all the way to the right through this maze:
Follow this path through the junctions: J, J, C, D, E, O, S, O, P, K, K, P, T, L, I, I, H, K, L. Now you can take the emerald-topped gold fitting. Back out for now and go around the tank until you find a small wooden table against the wall. Pick up the metal cross from here. Turn around to see 3 skulls etched on the side of the tank here, with markers between them. Next return to the large wooden table and look beneath it to see 2 rabbits etched here, with markers surrounding them. There is also a small wooden box, where you can insert your metal cross. Drag this down and take the small wheel.
Back away from the table and turn right until you see a shuttered window in the wall. Insert the small wheel in the ledge here and turn it clockwise to open the window shutters. Go back around the tank to find a drawbridge leading to a closed metal door. There are 4 winches that you can turn to adjust the shield images above the doorways, and the pattern you are looking for is based on the etches you have seen: skull-rabbit-skull-rabbit-skull. From the starting position:
- Turn the second winch until you see a rabbit on the second shield
- Turn the first winch until you see a skull on the first shield
- Turn the fourth winch until you see a skull on the third shield
- Turn the third winch until you complete the pattern
While you are here, turn right and approach the barrels. Take the drawing from on top of the standing barrel Scythed Chariot. Now go back and head through the opened metal doorway. Look at the series of 5 rings in the right wall here. You need to rotate these so the openings are all visible at the front. If they are numbered 1-5 from top to bottom, rotate them so you can see the openings in this order: 2, 1, 3, 4, 5. Now open the small hatch and take out a wooden handle.
Now focus on the lock on the gate ahead. Press the small square brick just above and left of the lock, and the lock will open. Push the gate further open, then approach the large chest. Turn the right dial until you see a partial keyhole, then turn the left dial to see a complete keyhole. Insert your small metal key and turn it to open the chest. Look inside and pick up a dagger. Examine this in your inventory - turn the dial on the hilt, then take the ruby-topped gold fitting from the end. Next look at the inside of the lid of the chest. Slide the top and bottom middle diamonds over the scratch marks, then pull open a secret compartment and take a metal lever.
Return back upstairs and approach the small table against the wall again. Turn the gear against the wall to the right so you are displaying a half-green and half-red shield here. Use your emerald-topped gold fitting in the middle of the circle of controls on the left (matching the green half of the shield). Use your ruby-topped gold fitting in the middle of the circle of controls on the right (matching the red half of the shield). Rotate the green circle anticlockwise 90° so the open slot is to the left side. Rotate the red circle clockwise 90° so the open slot is to the right side. Push both levers forward. Now you can pull open the drawer and take the metal head from inside. Examine this in your inventory. Add the wooden handle, then slide the two objects together and turn the handle. This will create a lever with a massive metal head.
Go back to where you started, and head up the small stairs to examine a hatch on the large circular tank. Use your Oculi Infinitum to see the inner workings of the lock, then follow these steps:
- Slide the top locking pin into the middle wheel, then rotate the wheel and slide this pin to the middle right bracket
- Slide the top-right locking pin into the top wheel
- Slide the bottom locking pin into the middle wheel
- Slide the bottom-right locking pin into the bottom wheel
- Slide the pin in the middle wheel diagonally down to the right
- Slide the pin in the top wheel down to the middle wheel, then diagonally up to the right
- Slide the pin in the bottom wheel up to the middle wheel
- Slide the top-left locking pin into the top wheel
- Slide the bottom-left locking pin into the bottom wheel
Now you can pull open the hatch. Use your lever with a massive metal head here, then pull the lever to open the tank. Go inside and read the letter on the stairs. Back out, then focus on the cannon to the right. Attach your metal lever to the wooden beam just right of the cannon, then pull the lever to release some cannonballs. Back out to the cannon. Now drag some gunpowder up and drop it into the cannon. Drag a cannonball into the cannon, then pull the lever just to the right, and the loaded cannon will face forwards. Focus on the loaded cannon, then aim at one of the clay pots and pull the left lever to fire. Keep loading the cannons, then aiming and shooting the clay pots until they are all destroyed.
Back out of the tank and approach the window where you opened the shutters earlier. Pull the chest forwards and examine the lid. There are 5 latches down the middle that you need to slide out of the way (either left or right). You must first adjust a series of blockers on the left and right:
- Move the first blockers on the left to their middle position
- Move the second blockers on the left fully up
- Move both sets of blockers on the right fully down
- Slide each of the latches to one side
Now pull open the chest lid and take a metal crank. Enter the tank and climb up the stairs. Insert the crank into the mechanism, then rotate it until the arrow marker points to the far left.
Once you reach the top, approach the window. Slide each part of the frame away from the middle, then open the window and climb through. Go down the stairs twice, then continue forward and you will look out to a small machine on a platform protruding towards the middle of the tower. Turn back to the right and look down behind the frame against the wall to find a drawing to pick up Revolving Bridge.
Now examine the small machine on the platform. Rotate the wheel until you can see a hexagon and a diamond formed by the rotating shape segments. The stairs will change, and you will automatically continue forward. Pull open the wooden gate, then go further forward and look at the diamond-shaped opening on the left wall. Rotate the two dials on the left and right to position the moving golden symbol over the fixed silver symbol. Go up the new stairs and take the ring-shaped part of a device in front of you.
Back out and turn right, approaching the wardrobe with the large golden disc. Focus on the disc, and rotate the silver ring so its openings point to the left and right - the 2 knobs will slide towards the middle of the disc. Now rotate the gold and silver rings so they have matched openings at the top and bottom - 2 more knobs will slide towards the middle of the disc. Rotate the knobs clockwise until the center aperture is completely opened, and a metal ball emerges. Rotate this ball so you see 3 complete shapes (circle, square and diamond) merging with the pattern around the edge. Now take the square medallion from inside.
Back out and go around to the left, approaching the ornate strongbox. Press the small button in the middle, then rotate the star so there are matching symbols around the edges, and slide the doors completely open to reveal a puzzle with 4 levels. Drag your square medallion here to activate. Now use the controls at the bottom to move the medallion around the puzzle, going over each space once. Here is one way to solve each level:
- Up, right, down 3 times, left 2 times, up 4 times, right 3 times, down 4 times.
- Right 5 times, down 3 times, left 4 times, up 7 times, left 2 times, down, left, up, left 2 times, right, down 2 times, right, down 2 times, right.
- Down 2 times, left 2 times, up, right 2 times, down, left 2 times, up 3 times, right 3 times, up, right, up, left, up, right, up, left, down, right, up, left 2 times, down, left, up, left, down 2 times, left, up, left, up, left, down 2 times, right, down, left, down 3 times, up, down 2 times, right, up.
- Up, right 3 times, up 2 times, left 2 times, down 6 times, right 2 times, up, down, up 2 times, left 4 times, down, left 2 times, down, left, right, up 3 times, right 2 times, up, right, left, up 3 times, left 2 times, down, up, down 2 times, right 2 times.
Look in the top of the cabinet and take the cogwheel. Read the crumpled note. Use your Oculi Infinitum and move the papers until you find one with 4 glowing symbols: hexagon, circle, diamond, square.
Return to the wardrobe with the large golden disc, and insert the cogwheel into the spinning mechanism. Wait as the wardrobe transforms. Drag the symbols at the top into the same order as the glowing symbols you just found (hexagon, circle, diamond, square). Now pull the lever on the left and the wardrobe will transform again. Pull open the drawer at the bottom, and take the silver disc and the golden dial with a cogwheel.
Go up to the top of the stairs again. Examine the part of a device you got from here earlier, and attach the golden dial with a cogwheel, then push them together and rotate - this will create a dial gear assembly. Use this on the large round machine. There are 4 discs that you can turn below, but you don't know the correct settings yet.
Return to next to the ornate strongbox you opened earlier, and look at the round astrolabe device just to the left. Insert your silver disc in the middle of the astrolabe. Use your Oculi Tempus - trace the shape, then drag the time-line back until the 4 markers all line up at the top. Spin the middle disc on the machine to achieve the same position, then pull the lever on the left. Take the small key from the new opening in the machine. Stop using the Oculi Tempus, and turn to look at the side of the strongbox. Slide the golden pyramid down to reveal a keyhole, then insert your small key and turn it. Grab the strangely-shaped tool.
Look back at the astrolabe and notice that the 4 markers are number 1-4. Pay attention to the symbols for each number, then go back to the top of the stairs. Adjust each of the discs to show the following symbols from left to right:
- Full white moon
- Full yellow moon
- Half white moon (right half white)
- Crescent yellow moon (right 1-segment yellow crescent)
If everything is correct, the central display will now be glowing blue, with a series of changing symbols around the edge. Grab the marker around the edge and drag it to get the different inner symbols overlapping and the blue will change to white, then the whole device will rotate. You will be looking up at a box beneath the device. Use your strangely-shaped tool on it and turn the device to open a compartment, then take the key with a cross-shaped head from inside. Go back to the astrolabe and insert this key in the middle. Turn the key anticlockwise until the markers move again.
Use your Oculi Tempus again- trace the shape, then drag the time-line back until the 4 markers all line up just left of the bottom. Manually drag the 4 markers to this position, then stop using the Oculi Tempus. Pull the lever on the left, then take the silver four-tipped medallion. Note the 4 markers around the astrolabe and the associated symbols, then go back to the top of the stairs. Adjust each of the discs to the new settings:
- Crescent white moon (right 1-segment white crescent)
- Gibbous white moon (top-left large white gibbous)
- Crescent white moon (right 2-segment white crescent)
- Crescent yellow moon (left 2-segment yellow crescent)
The central display should now be glowing blue again. As previously, use the marker to overlap the inner symbols and the device will rotate. Go down the stairs and look up at a new box beneath the device. Slide the 2 latches inwards, then pull the compartment down and take the ironbound wooden wheel. Back out and use the small machine in front of you. Rotate the wheel until you can see a diamond and an octagon formed by the rotating shape segments. The stairs will change back to their starting configuration. Go all the way back up to where you entered. Examine the wooden contraption here. Insert your silver four-tipped medallion on the front, and your ironbound wooden wheel in the top.
Climb down the stairs through the new opening.
Look just to the right of the boiler to see a small bookcase against the wall. Zoom in to the bottom of this to find a drawing Flying Machine. Back out again and look left to see number II. Turn the cogwheel beneath this until it comes off in your hand. Now look at the 4 levers here using your Oculi Infinitum. Turn the 4 levers so their inner mechanisms are aligned - this will adjust one of the three components on the front of the boiler.
Next go over towards the gate to the right of the boiler. There is a lever on the wall, and further to the right there is a square hole in the wall. Insert your cogwheel into this hole, then use your Oculi Infinitum again to see a hidden mechanism behind the wall. You can use the cogwheel on the right to select which tumbler to move, and the lever on the left to move the tumbler up or down. From the starting position, you can get the tumblers into position with these moves:
- Select tumbler 6, move lever down
- Select tumbler 8, move lever up
- Select tumbler 6, move lever down
- Select tumbler 8, move lever up
- Select tumbler 4, move lever down
- Select tumbler 8, move lever up
- Select tumbler 4, move lever down
- Select tumbler 5, move lever up
- Select tumbler 3, move lever down
- Select tumbler 5, move lever up
- Select tumbler 3, move lever down
- Select tumbler 1, move lever up
- Select tumbler 3, move lever down
- Select tumbler 1, move lever up
- Select tumbler 2, move lever down
Head through the gate and up the stairs. Head over towards the desk on the right and read the letter. Pick up the wheel with four handles, then focus on the microscope. Look at the back of the microscope and pick up the empty test vial. Back out 4 times so you are at the top of the stairs, then look left and go to the workbench. Focus on the front of the table - attach your wheel with four handles, then turn it clockwise until you can remove the barrel screw. Now look at the next device to the right, and insert the barrel screw here. Turn this clockwise, then open the gate and pull the lever to lower a shelf nearby. Go to the shelf and pick up another wheel and a wooden box.
Go back to the desk with the microscope and place the wooden box on the right. Open the latch on the top of the box, and it will completely open. Take the small lens from the side of the box. Back out twice and examine the microscope. Use the lens on the rotated cap on the top of the microscope, then rotate it down.
Go all the way back downstairs to the boiler, and approach the number III. Place the wheel from your inventory on the empty shaft to the right. Use your Oculi Infinitum again, then use the 2 wheels and the lever until the 4 mechanisms are aligned - this will adjust another of the three components on the front of the boiler.
Examine the dripping green liquid from near the number III, and collect some in your empty test vial. Go back upstairs and place your filled test vial in the stand behind the microscope. Now look to the left and rotate the mirror next to the flame, to focus the light on the test vial. Use the microscope and turn the lens to focus the image. Notice that all the shapes in this liquid are tetrahedra. Take the medallion from the opened compartment at the base of the microscope. Back out so you can look at the right side of this table. Insert the medallion here, then rotate it, open the hatch and pick up a lever from inside.
Head downstairs once more and approach the number I. Insert the lever at the top of the vertical pipe here. Use your Oculi Infinitum again. You need to move the lever around to align the inner mechanisms. From the starting position, move the lever down, far left, down, far right, down, far left, up, to the middle, down twice and far right - this will adjust the last of the three components on the front of the boiler.
Go to the boiler and pull the three locks open, then lift the main lid. Pick up the small flying machine model from the right. Go back upstairs to the microscope table, and place the flying machine model on the stand in the middle of the opened wooden box. Now look through the lens on the front of the box and rotate until you can see 3 pairs of symbols - you are looking for a square with a cross through it to appear on the far left (this is actually an octahedron viewed from one end). When you are correct, the purple vial will stand up. Pick up this full test vial, and place it on the stand behind the microscope. Turn the stand, so that the light is hitting the purple vial. Use the microscope and turn the lens to focus the image. Count each of the different shapes you can see here: there are 4 dodecahedra, 2 octahedra and 8 tetrahedra. Take the golden handle from the opened compartment at the base of the microscope.
Go downstairs again and use the Oculi Infinitum to see a glowing symbol to the left of number I. Now focus on the boiler and insert the golden handle in the small hole to the right of the opened segment. Drag the handle to the left to open another segment. Now you have a complex puzzle to solve:
- The glowing symbol to the left of number I is a dodecahedron, and there were 4 of these in the purple liquid
- The green liquid coming from number III contained tetrahedra, and there were 8 of these in the purple liquid
- By a process of elimination the number II is associated with octahedra, and there were 2 of these in the purple liquid
The code you need to enter in the new opened segment of the boiler is therefore 428. Rotate the red dials on the left to display these numbers:
Now look below this segment and rotate the 3 dials here to show the symbols that were paired with the shapes on the sails of the flying machine model:
- I - dodecahedron - looks like a lowercase letter h
- II - octahedron - looks like a saxophone
- III - tetrahedron - looks like a simple loop
This segment will now close, and the previous one will be active. Look left and pump the handle 5 times so the gauge is completely filled. Now you need to light the 6 flames. If they are numbered 1-6 from left to right, use lighters 5, 3 and then 4 - unfortunately the 4th lighter will break and fall off. Use the pump handle again, then use lighters 5 and 3. Go upstairs and cross the room to look inside a partially-opened wooden cabinet. Pick up the lighter from inside.
Go back downstairs and attach your lighter where the other one fell off, then spin it to lock it in position. Now use lighters 4, 1, 2 and 6. Go upstairs and cross the room to the cabinet, now taking out a lever. Go back to the top of the stairs and use the Oculi Tempus to see some white splatters. Click on these, then trace the shape, then watch the time-line. Stop using the Oculi Tempus, then go over to the large device to the left of the microscope table. Insert your lever on the left. To adjust the gauges, you move the bottom guide to where you want to remove liquid, move the top guide to where you want to add liquid, then pull the lever. You need to set the gauges as follows (based on the vision you just saw):
Now pull the large lever forward.
