Human: Make a concise location description of a lonesome scene inside a building hallway with a dragon, coals, and a ladder. Assistant: 
Set up in the center of this long corridor is a large glass cylinder filled with glowing coals, lending both heat and a strange orangish light to the room. Curling around the northern wall is a dragon forged from solid iron, its eyes dimly aglow with gaethzen orbs. A ladder goes up into the ceiling in the far northeast corner, seemingly leading to nowhere.
