Hall of Infinite Doors

As you continue further down the hallway, clouds of thick, scented smoke billow around you. You see indents in the wall at chest height where burn hot coals, and a strange powder sprinkled upon them is burned but not consumed. The smoke smells of spices, of perfume, of salt and of decay. You can barely make out the continuing hallway, and the "doors" are merely rectangular openings in the wall, hung over by thick curtains.
