Omis-Prion

Omis-Prion is a tomb world in the Vigilus system, on the Nachmund Gauntlet, and is distinct from the planet Vigilus itself. Its defining feature is a set of Necron complexes beneath the crust.

These Necron complexes attracted the interest of the T’au. During the War of Beasts, the conflict fought across the Vigilus system, Omis-Prion was treated as a neighbouring contested location. It is recorded separately from Vigilus and carries its own OPCM timestamps.

Omis-Prion should not be confused with the hive-war on Vigilus associated with Marneus Calgar. Its standing rests on the Necron tombs beneath its surface and on its status as a distinct location adjoining that larger campaign.
