From publisher blurb:
An unknown shift in spatial geometry has occurred aboard Sierpinski Station. Corridors loop endlessly and the entirety of the station is nested within itself. A station within a station within a station...into infinity. The station is decaying, the crew is losing their minds, all while a fear-sniffing beast from another dimension stalks the labyrinth: the dreaded Hound of Tindalos.
Navigate into a fractal maze. Plunge into madness and death as space twists itself around you. Find the source of this spatial insanity, elude the Hounds of Tindalos, or escape with your life.
This is a single-page, front and back module for the sci-fi horror RPG, Mothership (although it can be hacked into other OSR-type games). Optional files include a larger map of the station, proof of solvability, and an older version of the map with nested stations as a visual aid for how Recursion Rooms work.
