The party begins a search of the room, and Lillian is more calm now that her primary combat buff has subsided.
This part of the fort was used to lodge its mercenaries. The dormitory is sparsely furnished with bunk beds, wooden lockers, stools, and coal braziers. The beds are all carefully made and all gear is properly stowed in the chests as if the room were ready for inspection. An arrow loop opens on the southwestern wall and a door is to the northeast and more to the south another is to the east. Two other doors north and south (the south the one you entered). To the north of the room, an archway to the west leads to stairs that go upwards to one of the turrets.
There is a half-drunk jug of milk stored beneath a bunk. Now, days later, the jug of milk has spoiled, leaving a thick curd floating atop the vessel and stinking up the barracks.
This what the party found on a quick search after about two minutes.
