Necromunda System

The Necromunda System is a Segmentum Solar hive well that has spent fifteen millennia turning ore, people, and waste into guns. Necromunda itself is the hive world; moons such as Juggerata and sister rock Somnus share the ash-choked star.

House Helmawr rules from Hive Primus; everyone else fights in the spires, the underhive, or the wastes. The Imperial Fists still recruit here, and the planet's older name, Araneus, belongs to a continuity the Great Crusade burned.

The Necromunda System still matters because if you want a typical hive well, this is the one the setting keeps returning to. Unofficial fan notes keep the Solar parent and refuse to treat the pin as a random underhive page.
