The Massacre of Kormarg was an Imperial military campaign conducted by the morose Star Phantoms Space Marine Chapter against the vile, chiropteran xenos known as the Khrave Marauders on the Fortress World of Kormarg II in 718.M39. By 710.M39 Kormarg II, a world on the edge of the Sakkara Sector, had been besieged for more than two standard centuries by the Khrave Marauders. Kormarg had held out against the odds and had not fallen, but the world had been laid waste in the process. Taking it upon themselves to answer the defenders' long-standing plea for help, the Star Phantoms' Chapter fleet atttacked en masse, swiftly encircling the Khrave nest-webs in orbit and blasting them apart with concentrated fire from their Bombardment Cannons.
