Damnation of Eulta

The Damnation of Eulta was a joint-xenocidal campaign carried out by the Lightning Wraiths Space Marine Chapter against an unnamed Ork WAAAGH! upon the world of Eulta. Later, the Lightning Wraiths were joined by their fellow Chapters from both the Angels of Absolution and the White Scars Chapter to help quell the uprising and cleanse the planet of the foul greenskin presence.

Background
The planet of Eulta, a Lightning Wraiths recruitment world, was under attack by Orks by an unrecorded Ork warlord. His concoction proved to be a little too effective as the feral orks on the planet pledged themselves to become a part of the Warlord's WAAAGH! with the promise of a worthy fight. This resulted in a full-scale WAAAGH! breaking out on the planet's surface and required the intervention of the Angels of Absolution along with the White Scars to completely quell. Atlan Khassim was shamed and would have been interred to the Dark Prophets when a Lord Inquisitor took interest in his work and requested that he be sent to the Deathwatch for a Long Vigil, in order for his research to thrive.
