Vengeance from the Void

Vengeance from the Void is a notable Imperial castigation launched by the newly incepted Ordo Angelus Space Marine Chapter, a notable Successor Chapter of the noble and ancient Blood Angels. The early centuries of M32 were a tumultuous time in Imperial history, as several hundred systems throughout the western regions of the Segmentum Solar were subjected to the encroachment of a large invasion comprised of various Traitor Legions of the Forces of Chaos. Facing inevitable defeat, this conflict was only turned around by the timely intervention of multiple Chapters of the Adeptus Astartes, including the newly create Ordo Angelus. Only through the coordinated efforts, personal sacrifice and heroism of these Angels of Death, was inevitable defeat turned into a renowned victory.

History
Across a hundred scattered systems in the western marches of the Segmentum Solar, cult uprisings led by a core of Traitor Astartes warbands drawn from the Iron Warriors, Night Lords and World Eaters Traitor Legions bring entire planetary governments to their knees in a year of blood and anarchy. With whole sections on the brink of collapse, events take a dramatic turn when a combined force of the Adeptus Astartes emerges from the black depths beyond the spiral arm and launches a sudden and overwhelming attack directly upon the uprising's command. Though many Space Marines fall in glory, the warlords of the Traitor factions are slain and the uprising fractures into a thousand localized rebellions which are soon put down by local forces. Subsequent Inquisitorial studies claim that these Space Marines are drawn from several Chapters, including the newly created Ordo Angelus. Extant evidence however, including the projected deployment dates, contradict these assertions, consigning the entire event to conjecture.
