Caliban Sector

The Caliban Sector is the Segmentum Obscurus cube around the destroyed Dark Angels home, the administrative box above Caliban Sub-sector and leftover rocks such as Orphia.

The Lion and Luther broke the world at the end of the Heresy; the Rock is what remains of that gravity well. This row is the sector paperwork, not a second Caliban planet page.

The Caliban Sector still matters because the Unforgiven still navigate from a wreck they refuse to rename. Unofficial notes keep the Obscurus parent; Caliban stays a grandchild via caliban-system.
