Apollonia

Apollonia is a sunless Inquisition moon north of Segmentum Obscurus, the reliquary that hid the Athenaeum of Kallimakus until Ahriman tore the rock apart. This map keeps kind as moon under Obscurus, with the Appollonia spelling as an alias.

The moon rode a gas giant in permanent eclipse, stuffed with blanks, orbital guns, and a library that held the moon together. Ahriman spent Sanakht to carry the Athenaeum out; Grey Knights and an Inquisition fleet arrived into a civil war in his own armada; Space Wolves made the shooting worse. The moon imploded into a warp storm.

Apollonia still matters as the Ahriman: Sorcerer heist, not a Grey Knights Titan-sister and not an Eisenhorn shrine. Unofficial summaries keep the Obscurus parent and the moon kind.
