21. This room is quite small and dusty, cobwebs hang from the ceiling. A very ugly carpet lies on the floor, chewed up from bugs. In the corner of the room is a small stool with a few scrolls of paper and a glinting small silver object.
This secret room can only be opened by a key. The mage in room 20 has it. In order to open the door one must use the key. On the book shelf under a book is a key hole. If the key is turned to the left it disengages the trap, if it's turned to the right the trap remains active. If the trap is activated and someone steps into the room, they will fall ten feet thru the false floor that is located under the moldy carpet. 1d6 damage, save vs spell for half.
The two scrolls are “scrolls of remove paralysis”, the glinting object is a silver token with a bearded dwarf engraved upon it. If the coin is flipped all of the PCs will travel back in time one day. The coin will then disappear and reappear somewhere in the dungeon.
