Editing Purity wardens (section)

==Chapter Organisation==

===Recruitment===
People from Mare Aeternam are great material for Space Marine transformation as they are toughened by the planetary environment and are totally confident in their own strength and abilities; they know that for every child who has made it to adulthood, about 10 were deselected by the government, ensuring that those who remain are the greatest sons of their ancestors.
The best of the best get the right to take part into the Recruits' Tournament. Every generation in every city the apothecarium  - the symbol of humanity's power – comes to declare the beginning of the tournament. The top hundred winners leave their planet and never came back. The Space Marines take the teenagers to the orbiting battle-command barge ''Conquerors' Palace'' where the hellish trials of recruitment commence. Survivors-- less than 10% from all challengers-- become members of a final gladiatorial tournament; only those fortunate enough to survive have are allowed to undergo the transformation to a Space Marine.

===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.

===Battle Brotherhoods=== 
During the final steps of the Recruits' Tournament the future Marines form associations that become the foundation for the battle brotherhoods – the smallest combat unit of the chapter. The purpose of this brotherhood is to for the marines to become as one, the unit more than just a sum of its parts. 

Eventually the marines completely reject their weak and pathetic emotions and individual desires in order to serve the main goal – extermination of the Emperors enemies without remorse, mercy or compassion, as cold and pragmatic as the winds of their home world.

===Praetorium===
Many battle brotherhoods start to lose cohesion due to the high casualty rates of the Purity Wardens. As the survivors are often the most experienced and mighty warriors of their chapter, they earn the honor to become a part of a Praetorium (some kind of analogue to a typical first company), gaining access to a wide variety of improvements such as being issued improved or specialist weaponry, or becoming a chaplain after some sufficiently dangerous ritual. The most glorious among all can even try to become the private security of the Chapter Master.
