Hephaestus

Hephaestus' Cabin looks like a small factory, with brick walls and smokestacks like the forges and lots of gears around the entrance. Inside: "Steel bunks were folded against the walls like high-tech Murphy beds. Each had a digital control panel, blinking LED lights, glowing gems, and interlocking gears. A fire pole comes down from the second floor. A circular staircase led down into some kind of basement. The walls were lined with every kind of power tool imaginable, plus a huge assortment of weaponry. A large workbench overflowed with scrap metal---screws, bolts, washers, nails, rivets, and a million other machine parts."
