On the road coming home from vacation, and don't have time to do room 2 in the detail I wanted so this is out of order...
Room 9:
A 5'x5' room with a 10' ceiling and the holes to the toilet above in room 5. The bottom 5' of the north and south walls clearly seem like they should move, and 20 Str check can forcibly slide them up against some resistance (with something able to support 100 pounds weight being enough to easily keep them propped open at whatever height they are lifted to; they will slowly shut once that is removed). The north wall door opens at 12 and 4 (both am and pm; goes to room 8) and the south wall door opens at 6 and 10 (both am and pm; goes to room 10). From 4-6 and 10-12 there is a medium gelatinous cube doing cleaning duties (5'x5'x5' with 5' pseudopod reach 48hp; it doesn't carry inorganic material in itself from room to room ). At other times during the day there is a 50% chance the room is clean (exceedingly clean, except for the part of the toilet above ceiling level), and a 50% chance someone has done their business. At night the chances are 80% and 20%. At present there is a small crystal globe lying on the floor as well as 4 gp, 7sp, and 2cp. The crystal globe has a crack in it, but radiates illusion magic. When rubbed an image appears inside showing what is apparently a dwarvish lovestory with the words they are saying appearing in small dwarvish text (anyone familiar with such things will recognize it as a pretty famous one; when suitably engrossed the crack could probably be ignored, but is still annoying). It belonged to one of the now deceased dwarves.
