Ryza System

The Ryza System is the plasma forge well of the Aurus Sub-sector, second only to Mars at the end of the Crusade and famous for Executioner and Stormblade patterns. Ryza itself treats every battle as a weapons test.

The Heresy billed the priesthood for that pride. Two Ork Waaaghs and a daemon invasion have since chewed the dunes. Some older armour books park it in Segmentum Solar; this map keeps the Ultima / Aurus pin just east of Terra.

The Ryza System still matters as the Imperium's plasma foundry. Unofficial summaries keep the Aurus parent and do not relocate the forge to Mars's backyard.
