Defense of Ashimar

The Defense of Ashimar was a joint-Imperial campaign conducted by the Blades of Morkai and Angels of Calth Space Marine Chapters as well as the Astra Militarum regiments from the Ashimar Nova Guard against a Khornate warband known as the Promise of War Unending and their allies from the Word Bearers Traitor Legion in the Ashimar System.

History
When the Khornate warband known as the Promise of War Unending invaded the Ashimar system, two Chapters answered their call for aid--the Angels of Calth and the Blades of Morkai. As soon as they realized the warband they were fighting was derived from the Word Bearers, the Angels of Calth attempted to wipe out the entire system from orbit via Exterminatus. The Blades of Morkai refused to let this happen, however, and engaged the Angels of Calth in void combat while deploying their Marines to the surface to save Ashimar. Despite fighting on two fronts, the Blades were fighting in their element on both fronts, and were able to defeat both enemies with the aid of the Ashimar Nova Guard and Battlefleet Ashimar.
