You are in what would appear to have been the armoury of the Pyramid Guards, as sword racks line one wall, and various impressions of crossbows and the like can be seen on the wall.
Unfortunately the heavy wooden door that kept this room secure has been smashed apart unceremoniously, and the wooden splinters lie around the frame of the entrance.
Not much has been left unbroken in this room by who or whatever raided it, though it is also apparent that nothing much was stolen only smashed, suggesting that he/she/it has no need of normal weapons!
Exits lead east through the doorway.
