I've marked the direction of rotation for all the rotating walls with arrows. I've also marked the four lever pairs with arrows pointing to the wall they control, but this could certainly be changed by the GM. There's a couple different possible interpretations of the way the rotating walls work:
- each wall only rotates when the proper lever is pulled;
- the walls oscillate, rotating to one position, waiting, then rotating back, unless the proper lever is pulled to stop movement;
- the walls all move in unison in either of the previous two manners when the levers are pulled in the proper sequence;
- the walls rotate randomly when explorers pass through that section unless they are turned off by the appropriate lever, or by the proper sequence of levers.
