Black Sun Crusade

Summary
Running from 832 to 845.M42 the Black Sun Crusade takes its name from the Black Sun of Medrengard, fortress world of Perturabo. It retrospect it seems clear that it was no independent effort on the part of Perturabo but intended as the first blow of a new Black Crusade. The frustration of Perturabo's efforts to take over the Aliris Sector clearly bought the Imperium a century and half of time.
