Nachmund Sector

The Nachmund Sector is the Segmentum Obscurus Gauntlet sector above Nachmund Sub-sector, the administrative cube of the corridor that was for a time the only stable crossing of the Great Rift.

Nachmund-subsector holds Vigilus; Gorandahl is the Sanctus Wall mouth. Calgar's war, Dharrovar's Knight treachery, and Haarken's pressure all land one level down. This is the sector box, not a synonym for Vigilus.

The Nachmund Sector still matters because the Gauntlet is a geography, not a single hive. Unofficial summaries keep the Obscurus parent and leave Vigilus under vigilus-system.
