Abandoned Camp- Bunker

Well, it is an engineering supply cupboard, rather than a janitorial supply cupboard.

The engineering room is dominated by a vast machine extracting geothermal energy and turning it into electricity. A pair of small, eight-legged spherical robot with eight arms is slowly touring the room, presumably keeping it (and themselves) in working order. A third such robot lies out of the way in the corner; it seems to have been cannibalised for parts by the other robots as its casing is open. Also lying nearby are some dead bodies, similarly garbed as the one in the computer room and equally mummified.
