The Ark is the building that serves as a storehouse for the village of Sparks. Kenny tells Doon that the front doors once had 'eyes' that could tell when you were coming (a primitive explanation of automatic doors). A partially unreadable sign above the door says 'UPE ARK', but because no one knows what it means, they just call it the Ark. It was like once a grocery store (SUPER MARKET). At the end of [[The Diamond of Darkhold, a library is created out of the building's back room, lit by the solar-powered diamonds.
