The artificial celestial body Aposimz has a diameter of 120,000 km. Most of its volume is the core, which is covered by a hyperstructural shell. Fifty centuries ago, people who lost the war against the core lost the right to legally inhabit Aposimz and were isolated on the frozen surface. They face the uncontrollable Frame Disease and aggressive automatons that frequently appear at the Ruins level. Despite this, people somehow survive.
