Cleansing of Caerulia IV

The Cleansing of Caerulia IV was an Imperial castigation campaign carried out by the Astral Leviathans Space Marine Chapter to defend the hive world of Caerulia IV against a large Genestealer Cult.

Background
The Cleansing of Caerulia IV was a small campaign where the 2nd and 3rd Companies hunted down and destroyed a large Genestealer cult prevalent on multiple Hive Cities on the planet of Caerulia IV. The campaign was won after Altum Dominus Calidus Sepheran killed the Genestealer Patriarch in the lower hive of the Hive City Oktania, after which most of the other Genestealers upon the planet quickly went into a state of disarray allowing the rest of the Argent Leviathans to quickly eradicate them.
