Incident in Redspeckle Mine, The (3.5e Quest)/The Azer Fortress
From Dungeons and Dragons Wiki
The Kuo-Toan ruins that the Azers have built their fortress in are not completely settled, or even regularly patrolled, by the Azers. The walls are hewn stone and floors are flagstone, which is usually broken in areas the Azers don't use regularly enough to clear. The fortress is dark except for the light of the Azers themselves.
