Put on the eyepiece and look at the lectern. A miniature observatory is at the top of the surface. Insert the metal casting on the door. Enter the model.

Inside the model is very similar to the second room. Locate a hexagon lectern. Take the handle and rotate the wheel counterclockwise until the dome open. Get a stone carving.

Check out the symbols on the pedestal. Go back to the telescope. Dial the moon wheel and star wheel to match the first two symbols. Then set the lens cover’s dial to match the third.

Go back to the second room. Locate a hexagon lectern. Insert stone carving. Then rotate the outer rings so the two triangles locked in place. The lectern surface will flip to reveal a puzzle. Move the tokens to match the markings on the floor. A globe will appear.

Check out the clue on the table. Three spots are circled in red.

Go back to the globe. Locate the first spot on the globe. Go to the green square panel on the machine and trace the symbol. The red light to the left of the panel will turn on. Repeat step for all three symbols. The green square panel will transform to a maze. Use the buttons on the wheel to navigate the maze. Use the ones on either side of the wheel to go left and right. Use the one on top to go forward.

Locate a poster on the wall. This is the solution for the maze puzzle. The goal is to activate the device inside the central chamber. The device will activate when you entered the room through all three doors.

Door ♏: Upon entering the maze. Turn right. Then turn right at first opening. Go to the end of the corridor, step on the pressure sensor plate. A ♏ symbol on the wall will illuminate. Turn around and go back to the walkway. Turn right. Continue going down the walkway. Turn every time you hit the wall. Until you can reach the central chamber. Enter the room and one of the pyramid on the table will activate.

Door ♎: Exit the central chamber. Follow the walkway. Keep going until you see a peep hole on the wall. Then you turn right on the next corridor. Go to the end and step on the pressure sensor plate to open the door. Turn around and make a left. Then left. Enter the central chamber which will activate a second pyramid on the table.

Door ♓: Exit the central chamber. Go straight until you hit the wall. Turn right. Turn left. Then turn right to go back on the the main walkway. Continue going down the walkway. Turn every time you hit a wall. Until you see a wreckage. Turn around and make a left. Pass the deep well.

Make a right. Turn left on the second corridor. Step on the pressure sensor plate to open the door. Turn around and left. Walk until you enter the central chamber. Inside the third pyramid will activate. The glass will break. Take the orb.

Go back to the courtyard. Place the orb on the last missing planet. The orb will open. Put on the eyepiece and enter the small door. Inside the orb is a rotating cylinder with a large handle on top. You need to move the handle to the bottom of the cylinder.

However the track is misaligned. Rotate the cylinder so the top track aligned. Slide the top small handle to lock the top track in place. Rotate the cylinder again so the bottom track is aligned.

Slide the bottom small handle to lock the bottom track in place. Once both tracks is aligned move the large handle to the bottom.

Press the bottom at the top of the orb. The planet will start rotating and unlock the pyramid. Grab the pyramid. You have completed the chapter!
