Editing History of the Green Men (section)

===Storm clouds gather===
To this day historians and Inquisitors alike argue what brought about the betrayal of the Legions that were commonly considered incorruptible back during the Great Crusade. Certain conspiracy theorists point at [[Uriel Starikov]] as the diabolical seeder who sowed the seeds of corruption in the hearts of his innocent brothers. As the ultimate proof of their theories they like to mention the Emissarium, a special purpose unit within the XIIIth Legion. For those unfamiliar with the subject matter, early in the Great Crusade, Starikov decided to send a trusted marine as an ambassador or liason to each of the Legions led by his brothers, ostensibly to foster inter-legion communication and help the Primarchs coordinate their actions. Most historians agree that the real purpose of this stratagem was threefold: to establish an intelligence network within other Legions, to earn the friendship of the few Primarchs still suspicious of Uriel, and to ignite and fan the flames of corruption. The latter was probably his primary goal: after all, you can always find a way to control that which is corrupt.

The Emissarius assigned to the Life Bringers was none other than Velzevul Quint, a brilliant Techmarine and a trusted confidant of Starikov himself. In a minor violation of the Emissarium's rules, he took a small retinue with him to Valetudinarium. Although initially the unexpected guests received a fairly lukewarm welcome and were treated with a bit of suspicion, it wasn't long before the strategic prowess and amiable personalities of Starikov's children had earned them the firm friendship of the Life Bringers. Quint and his retinue, in their turn, showed keen interest in the genetic research of their brothers, never tiring of giving compliments to their ingenuity and skills at gene manipulation that almost rivalled those of the Emperor himself. Ever so subtly, they were cultivating hubris in the hearts of the Genetors, pushing them towards the limits of the allowed. 

A skilful talker and a master of manipulation, Velzevul Quint soon became a close personal friend of [[Johannes Vrach|Vrach]] himself. During their long talks, the Techmarine expressed his fears for Mankind's future in a Galaxy filled with deadly disease. What use was it to reclaim Human worlds from the Xenos, barbarity or the fetters of religion, only to inevitably lose them to an enemy the Imperium keeps downplaying? These tirades were prepared based on a painstaking study of the Primarch's dossier, which included a detailed description of his life and several character studies. And, of course, they did not fail to resonate with Vrach's deepest concerns and suppressed fears. Increasingly absorbed by his insane dream to conquer all disease, the Primarch all but withdrew from commanding the Legion, leaving the warfare matters to Salk. 

It wasn't long before the Genetory ceased to be the cradle of life where new, perfected lifeforms were created to better serve Humanity in its struggles beneath the stars. It was now more akin to a hospital, with all of its brilliant minds consumed by studying pathogenic microorganisms and trying to devise better ways of fighting them. People who only recently wouldn't had been admitted to its halls illuminated by ultraviolet lamps, such as Librarians, became its frequent guests. During the course of his research, [[Wilmut Sachs|Sachs]] became concerned that sorcery may be a grossly undervalued asset in genetic engineering, and so he invited the Legion's psykers to his domain in order to see whether magic would achieve what his nanolancet couldn't. And although many Librarians recognised this as High Genetor's folly, he did find a number of like minded people in the Librarium. People like [[Vertumnus Alraun]], the Chief Librarian of Life Bringers.
