Hephaestus' cabin is made of brick and has a smokestack sticking out of it, like a tiny factory or like an oversized motor-home. The entrance is like a vault door, circular and of thick metal. It opens with a lot of gears turning and smoke hissing. It has shiny metal walls and metal slatted doors. It is noted for being unclean and messy, filled with junk most of the time. The interior of cabin consists of steel bunks folded against the walls with a digital control panel. The bunks lower into individual rooms.
