Corribra Sector

The Corribra Sector is a densely populated sector of the Segmentum Tempestus, south-east of Terra, whose Battlefleet is based at the hive world Thesselonia. The Sisters maintain an Arch-Abbey on Janus IV, and the sector forms part of the southern watch of the Imperium.

The space hulk Tyrant Immortal was sighted in the sector about two centuries before the Third War for Armageddon. Xenos and heretics exert pressure along every border of the sector. The Orrery map also carries a Corribra pin labelled Ophelia IV; this marker is distinct from the Tempestus cardinal world.

The Corribra Sector remains significant as a southern fleet neighbourhood of the Segmentum Tempestus. It is not to be identified with Ophelia VII. The site’s unofficial notes retain the Tempestus parent and do not merge the Ophelia IV pin with the Ophelia System.
