First Campaign of Damnation

The First Campaign of Damnation was a dubious campaign launched by the Sanctors of Lightrim into the Aomra Sector to supposedly cleanse it of Chaos cultists and various warbands, but in reality, it was a diversionary campaign so that they could secretly recruit those with psychic potential into their ranks, and exploit them.

History
The Sanctors of Lightrim conspired to create a campaign were they would try to attack the Sector of Aomra, a former Imperial region, were a huge number of Chaos cultists and Warbands had long ruled with an iron fist. But they were not launching this campaign for any benevolent reasons, but for purely selfish ones. In actuality, the Sons were using the campaign as a cover to gather recruits for their Chapter - especially those with psychic potential who could both wield and control the baleful powers of the Chaos, but preferably those who were somewhat sane who had not yet been driven insane by the sibilant whispers of the Warp. The Sons of Damnation's intent was to acquire a better understanding of the Ruinous Powers more than they already did. They assaulted the so-called Runic Worlds, killing the majority of the Renegade Space Marines and cultists that lurked there.

After they had their prize, the Sanctors brought these new Aspirants back to their Chapter homeworld. These Aspirants went under a series of thorough and gruesome tests, to determine their potential of becoming an Astartes. Those that survived these ordeals, were further trained by the Sons to control their innate abilities and implanted with the Chapter's gene-seed. Thus, the Sanctors took another step forwards down the path to damnation. One of these Aspirants was Hastur Kel'Thuzad, whose powerful psychic abilities would see his meteoric rise through the ranks to that of Captain of the 2nd Company.
