Sagan Subsector

The Sagan Sub-sector is the Karthago cube whose tithe-world Sagan III was the Badab War's logistical door rather than a Chapter home. Astral Claws virus-weapons tried to deny it; loyalists made it the Imperium's main door into the Maelstrom Zone.

Sagan I through VII, Gagan, and Bale share the chart. This is not Melchior, and not a random Ultima agri-belt.

The Sagan Sub-sector still matters as Badab's supply lock. Unofficial notes keep the karthago-sector parent and leave Sagan a child of sagan-system.
