Aegis Subsector

The Aegis Sub-sector is the Eastern Fringe administrative cube of the Thramas Crusade, the breadbasket neighbourhood Horus sent the Night Lords to terrorise so the Lion could not reinforce Terra.

Thramas and Heroldar are the named prizes; agri-worlds fed nearby forges until firestorms and bio-phage left ash. Konrad Curze and Lion El'Jonson duelled across this chart while Sevatar tried to hold a Legion together.

The Aegis Sub-sector still matters as the Thramas neighbourhood, not as a 40k shield-station label. Unofficial summaries keep the thramas-sector parent and leave the Thramas System a child of this row.
