Macharia

This Macharia is the sixth world of the Cadian System, a militarised hive and Gate holdout, not Lord Solar Macharius's shrine. Abaddon's Planet Killer wrecked it in the 13th Black Crusade; Cadia Stands says the corpse fell into the sun, while Reign of Iron still lists a mutated Imperial holdout. Keep the Cadian parent. Do not bury Macharius here.
