Port Maw Subsector

The Port Maw Sub-sector is the Gothic Sector naval-capital cube around the hollow artificial planetoid whose five-hundred-kilometre aperture named the station. The 60th Expedition found it in the Coronid Deeps.

Traitor officers turned its panopticon on loyalists in the Heresy; in the Gothic War Chaos blockaded it rather than storming the mines and forts. Kiliman IV, Bretz, Acre, and Kelshok Station share the neighbourhood.

The Port Maw Sub-sector still matters as Battlefleet Gothic's headquarters geography. Unofficial summaries keep the gothic-sector parent and leave the station under port-maw-system.
