Lyriax System

The Lyriax System is a Segmentum Tempestus well whose principal named world is the Aeldari-monitored rock Lyriax, a charted address rather than a Craftworld anchorage. This map keeps the Tempestus parent.

The child holds the Fifth-edition and Phoenix Rising map marks. This system row is the gravity well those marks sit in. No fleet-base gazetteer, no tithe grade, no published void battle. Jambonium still wanted a system cube, so the cube stays.

The Lyriax System still matters as the well for that watched world. Unofficial summaries keep Segmentum Tempestus, refuse to promote the pin into a sector, and do not invent a maiden-world cluster around it.
