(W/A/CA) Tsutomu Nihei. The artificial celestial body Aposimz measures 120*000 km in diameter. Most of its volume is its core space* which is covered by a superstructural shell. Fifty centuries ago* the people who lost the war against the core lost their right to reside legitimately on Aposimz* and were stranded on the frigid surface. hey face rampant Frame Disease and aggressive automatons which appear frequently on the Ruins Level. Yet even so* somehow the people survive.
