Editing Desert Raiders Chapter (section)

===Origins===
The Raiders were founded Late in M35 to counter the increasing Chaos incursions in Rovokan Sector. By the time the newly founded chapter was ready for deployment most of the sector had fallen into the hands of archenemy. Many in the newly founded chapter considered their mission lost before it began. Brother Draylon, the chapter's very first Chaplain, challenged this view, proclaiming it their holy duty to reclaim the sector for Terra.

Inspired by their Chaplains fiery oratory the young Chapter launched a brutal campaign of raids to weaken and destabilize the archenemy's forces. Forced by circumstances to conduct a guerrilla campaign to retake their sectors, the Desert raiders made a virtue of necessity. Striking from the Imperium's few remaining strong holds in the Corribak sub-sector, the Desert Raiders plundered the enemies supply lines and depots. Simultaneously weakening the enemy and adding to their own resources.

The forces of Chaos soon began to view the raiders with superstitious dread. They would strike, seemingly from no where, utterly overwhelm any defenses, and disappear with their loot before any reinforcements could arrive. Over the course of a century the constant raiding caused the breakdown of what little cohesion the followers of Chaos had maintained. 

With the forces of the archenemy in disarray a crusade was launched. Brother Draylon's preaching reached beyond his chapter, inspiring other Imperial forces to join the fight, and inciting local populations to rise up against their blasphemous overlords. Over the course of the next fifty years a grand war of faith, lead by the inspiring Chaplain, would reclaim the sector for Him on Earth.

Shaped by the war of faith led by their chapter in it's earliest days, the Desert Raiders are experts at fighting the forces of Chaos. they have a a particular loathing for traitor marines, and will go to great lengths to destroy any such noxious servants of darkness they encounter. They also eschew the use of Librarians, viewing psykers not soulbound to the Emperor as an inevitable source of corruption.

In M38 the Raiders launched a campaign against the forces of the Hellkin, a band of Chaotic pirates who had been preying upon Imperial Shipping in the Southern Segmentum Obscuras. Their raids against the pirates not only allowed them to slaughter many of the Chaos Space marines leading the Hellkin, it also lead to the rescue of Navigators who had been captured by the traitors and forced to serve them. In total, 37 Navigators who had been presumed dead were returned to their houses. In response, the Navigator house's Kelveck, Romulest, and Protarian have all pledged to provide the Chapter with their support in perpetuity.
