Formosa Sector

The Formosa Sector is this map's Segmentum Obscurus cube that holds Nemesis Sub-sector and Inquisitor Coteaz's Protectorate paperwork, a mash of the Eye-neighbour fortress and the Eastern Fringe Formosa of later Coteaz stories.

Nemesis Tessera, Epsilon Regalis, Glovoda, Lorgamar, and Vorath share the chart. Coteaz took the Protector title after executing his mentor Laredian; Grey Knights still watch quarantined Formosan seer-worlds in other sources.

The Formosa Sector still matters as this chart's Coteaz / Tessera neighbourhood, not as a relocated Eastern Fringe duplicate. Unofficial maps keep the Obscurus parent and leave Tessera under nemesis-subsector.
