Aviorus System

The Aviorus System is a star system of the Koronus Expanse, located in The Cauldron, a chart of unnamed worlds on Owlcat’s Rogue Trader void map. The Cauldron comprises burning, desert, jungle and gas-giant worlds, and it is not a hive cluster of the Calixis Sector. This site nonetheless retains the Cauldron Subsector as the system’s parent.

Owlcat’s void map places four unnamed planets in the system, which holders of a Warrant may scan, land upon and leave. No tithe grade, Chapter home or crusade designation has been published for it. The site keeps a system entry within the Halo Stars neighbourhood, and that entry remains in place although its constituent worlds are still labelled “Unnamed”.

The Aviorus System therefore serves as a defined location within the Cauldron rather than as an unclassified placeholder. Unofficial summaries preserve its Cauldron Subsector parentage, decline to supply colony names that the game does not provide, and treat the system as separate from the Koronus Expanse region entry.
