Well, this is terrifying. The location descriptions are evocative, the tables provide all kinds of horrible results, and the vibes remind me of Lynch's Dune (esp. your cover image). I've been a fan of prison modules since "In the Dungeons of the Slave Lords." Nicely done. How exactly do the "S" tunnels work; do they connect to one another (and perhaps to Shiv's secret kitchen tunnels) or is this left for the Warden to decide?
