Ichar IV

Ichar IV is a hive and industrial world north of Ultramar, exporting ore and myco-protein until a Genestealer cult called the Brotherhood seized it. Calgar put that rising down, then returned in 992.M41 when Kraken and a hidden brood overwhelmed the hives. He killed the Swarmlord in a rematch, but the planet was left in ruins and the Scythes of the Emperor were gutted.
