You are an astronaut whose wormhole technology malfunctioned, placing you lightyears away from Earth. You were forced to land on a planet, covered in ice and snow, engulfed in the darkness of having no stars nearby at all. The glaciers and ice ridges seem to host no life at all, much less food... And, without any solar energy, your ship's Potato Growth System might eventually shut down. Fortunately, your ship has a reliable drill system and can be a perfect submarine.
