A brightly lit home(ne)

At the back of this hut lies a large lit furnace, sending trails of scented smoke into the air and up the chimney. The dancing red flames cause flickering shadows on the walls and the two stained glass windows at the front of the house, lighting the room with an unsettling evil glow. Near the furnace is a large table, upon which various types of sand have been placed.
The northeast door is closed.
The only obvious exit is northeast.
