Editing Purity wardens (section)

===Chapter divergence===

During the millennia the chapter ended up in many fratricidal wars, causing serious losses, until by 37M the chapter reckoned only 200 brothers. It was a dark time for the Wardens; the full chapter was on the verge of extinction, but the grandmaster had a solution. First he decided to reject rigid Ultramarine dogma and form an assault company from the remaining marines, which became a future model for chapter organization. Furthermore, he got rid of the scout system in order to maximize the number of heavily armored soldiers that carrying heavy and special weapons for maximum offensive advantage against Traitor Marines. Purity Wardens often have numerical advantage against their enemies because of the low rate of Chaos corruption.

There was still a question of recovery of the chapter's previous strength. In order to overcome it the Grandmaster made a deal with the Adeptus Mechanicus: for the next millennium the full chapter was under the command of the Magos Bellum Patronum, without any right to reject his orders. In exchange he provided the technology which is now always used to create new Warden companies; using it allowed the chapter to create one thousand gene-seed zygotes in fifty years. This allowed the chapter to produce fifty to a hundred new marines with every new generation of the settlers of its home world. In the current timeline the chapter consists of ten assault companies, but its strength is actually unknown due to high casualties and turnover in the Ultima sector.
