Agripinaa Subsector

The Agripinaa Sub-sector is the Cadian Gate forge-neighbourhood that holds the Agripinaa System, the Orb of a Thousand Scars, plus hive wells such as Amistel. It armed Cadia for millennia from this cube rather than from the fortress world itself.

When Cadia broke, Albitern, Amistel, and the forge well became the remaining industrial spine. Traitor sieges treat this sub-sector as a shop window into the Eye.

The Agripinaa Sub-sector still matters because a Gate without shells is just a corridor. Unofficial maps keep the agripinaa-sector parent; Agripinaa stays a grandchild via agripinaa-system.
