Aquitaine Sector

The Aquitaine Sector is an Ultima Segmentum cube near the galactic core whose capital was Chemos, homeworld of the Emperor's Children, until the Dark Angels obliterated the mining world and declared the system Perdita.

Fulgrim's renaissance, the Legion's fortress at Callax, and Inquisition quarantine all point at this chart. The sector still has a name; it no longer has a living capital.

The Aquitaine Sector still matters as the Emperor's Children's erased address. Unofficial maps keep the Ultima parent and leave Chemos a child of chemos-system.
