Seelen Stream Sub-Sector: A Warhammer 40k Setting
42.112
Deep in the Segmentum Tempestus and imbedded along the outer edge of the Spartus sector lies the Seelen Stream. A stretch of Imperial systems providing one of the few stable corridors to the outlying sectors and a bastion of opportunity and danger with its bordering frontier space. A corridor proved even more vital upon the onset of the Cicatrix Maledictum.
