The exact solution follows next:

1. Cast Dispell Illusion to reveal an opening under the western stairs. Walk through and push button B1 to open door D10.
2. Now walk up the stairs and push the buttons B8 and B9 to open the doors D1 and D7.
3. Go back downstairs and walk onto teleporter T2 to get teleported to T7.
4. Push button B11 to open door D6, then enter teleporter T6 to return to T1.
5. Take the key out of chest C3, then again use teleporter T2 to get to T7.
6. Unlock door D9 with the found key, then walk downstairs.
7. Open the secret door right next to the stairs and enter the teleporter T8 to get teleported to T4.
8. Push button B10 to open door D2, then enter teleporter T5 to return to T3.
9. Go upstairs and enter teleporter T6 to return to T1, then push button B2 to open door D4.
10. Use teleporter T2, then go downstairs. Disarm the chest C2 with Destroy Trap, then take the fire key from it.
11. Use teleporter T6, then go downstairs and unlock door D3 with the fire key. Take two Order cubes, then use Destroy Trap to disarm chest C1 and take the ice key from it.
12. Use teleporter T2, then go downstairs and unlock door D5 with the ice key. Take two Chaos cubes.
13. Finally leave the room puzzle by using teleporter T6 and walk to the main hall.

Trivia

• As a rule of thumb, all the buttons on the western Order side have to be pushed, while on the eastern Chaos side, the only button that should be pushed is B11, as all others on that side only close doors.
• Using the spell Telekinesis, one can make things much easier by simply pushing the correct buttons (B1, B2, B8, B9, B10 and B11) from a distance, thus saving the Avatar quite some back and forth between the sides. However, getting the cubes with the Fetch spell is not possible.
