The Atelier is the final room in the Dungeon stage, and the only room of the Black Area. It includes the Final Stage sculpture, surrounded by a fence, with a vase seated within the fence's gap. If Ib sleeps on the Final Stage, you will get you the ending Ib All Alone. However, if Garry is with Ib, he will prevent her from sleeping on it. The Black Key can be found in the northern-most part of the room. This room exits into the main gallery, thus concluding the Dungeon.
