Silo 17

Silo 17 is a place name in a world kept underground: shafts of concrete and steel sunk more than a hundred levels into the earth, spiral stairs beneath grow lights, machine floors in the deeps, sealed doors against a forbidden outside. The name Silo 17 belongs to that buried world, an address in the same architecture of stair and landing, level and door. Like every address in that world, it belongs to a world of routines: shift bells, market landings, and the slow economy of a place where everything moves by hand, up and down the great stair.
