Destruction of the Sun Eaters

The Destruction of the Sun Eaters was the name of the Imperial castigation campaign carried out by the wrathful Emperor's Reapers Space Marine Chapter against the Sun Eaters Renegade Chapter, which fought on the side of the Renegade High Lord Goge Vandire during the Age of Apostasy.

Background
During the dreaded Reign of Blood the Emperor's Reapers Chapter engaged and purged many chapters loyal to the Apostate High Lord Goge Vandire. As the vengeful executioners wiped out worlds controlled by the Brides of the Emperor with virus bombardments, the Chapter instead focused on eliminating the other traitor Chapters and to make haste to Terra in a attempt to execute Vandire themselves, but were halted from taken upon in the final campaign by the Sun Eaters Chapter. In a nine-month long skirmish, with most of the Sun Eaters killed, and those that survived having fled for the Eye of Terror, the Chapter discovered that Vandire was killed by his own bodyguard, ending the Age of Apostasy.
