This is a fantastic science-fantasy vault that perfectly captures the Vaults of Vaarn tone. The premise of exploring a decaying space station, complete with space walks and depressurisation hazards, is a great contrast to the typical desert setting.
The time-limit mechanic, driven by the station's decaying orbit, is an excellent way to create tension and drive the adventure forward.
The entire document is well-presented, with a clear layout and a map that has a great, retro-computer aesthetic. Well done on a very creative submission!
