For decades, the Arceon asteroid — orbiting close to a giant star — has been home to a mining operation and a secret research station. Something discovered in that station recently resulted in a catastrophic invasion that has overrun most of the facilities. That same discovery also altered Arceon's trajectory. The asteroid is now on a collision course with the star it orbits, which will destroy everything on it. As one of a small number of survivors of the invasion, the only objective remaining is to cross the asteroid and reach the escape ships that managed to get clear of the station before everything went wrong.
