Scarus Sector

The Scarus Sector is the Segmentum Obscurus Eisenhorn neighbourhood named for a Word Bearers captain lost in the warp, the cube of Helican, Angelus, Ophidian, Vincies, and the Vraks armoury well.

Thracian Primaris, Gudrun, Eustis Majoris, and a generation of Inquisition wars land here. Orks moved in after the 13th Black Crusade; the Blood Star Campaign already billed three Chapters their masters.

The Scarus Sector still matters as the Obscurus case-file capital, not as a random Gate label. Unofficial notes keep the Obscurus parent and leave Vraks under vincies-subsector.
