Equixus

Equixus is a sunless Ultima hive world, the Lord of the Night stage where Night Lord Zso Sahaal woke ten millennia late to hunt the Corona Nox. This pin is that Spurrier hive, not a well-lit agri-world with a similar spelling.

Interrogator Mita Ashyn's Inquisition cell came looking for petty heresy and found a Terran-born captain walking the underhive like Nostramo had been rebuilt in the dark. Gangs, death-cultists, and Krieg Acerbus's later claim on the Corona all spent Equixus as scenery. The sun never arrived to argue.

Equixus still matters as Sahaal's crash-hive. Unofficial fan summaries keep the Ultima parent and do not file this row as Nostramo, Tsagualsa, or a random night-side mining rock.
