Edit: I had deleted the treasure content of the chest because I was going to change it, then forgot to actually do so. Sorry! The chest contains 300 gp in addition to the listed books. Module text now reflects that change.
The dungeon I am currently running is not a megadungeon and has a much smaller conceptual area, so the rotating room the players dealt with yesterday worked quite differently; it was more of a puzzle room than a control point, and there were no guards or living areas. Instead, the room rotates continuously, and in the center of the room is a capstan. Turning the capstan in different directions changes the rate of rotation:
- Reference Point: room rotates counterclockwise once per day
- 1 Complete Turn Clockwise: room stops rotating
- 1 Complete Turn Counterclockwise: room rotates once per hour
There's another capstan in one of the connecting rooms which has the same effect. The players figured this all out, so they can now enter and exit the area without problem.
