Reign of Winter
A bearskin rug dominates the floor of this trophy room, and the heads of several deer have been mounted on the walls. Doors lead to the north and south, while two short hallways continue farther east, where you can see the sleeping arrangements for a great, many bandits.
From the glow coming from the room to the east, you can safely assume there is a large fire there, and many of the bandits seem to have elected to sleep near it rather than take one of the more isolated rooms.
DC 20 Perception
There is a crease in the floor beneath the bearskin rug…
Upon closer inspection and removal of the rug, you see that there is a trap door here, secured with a heavy iron padlock.
