===The Culling of the Genetory===

Although the Life Bringers were quite successful as a Legion, Johannes Vrach cared little for conquest. He was certain that the Imperium kept downplaying the danger the numerous diseases of the Galaxy posed to humanity's restored domain. Since his reunification with his Legion, he had seen malaises that made the great blight of Rai look like common cold, and he was sure that he had yet to encounter the worst of them. The Galaxy was rife with diseases, and the Life Bringers could only cure a handful of them on the planets they discovered. This was clearly not enough for Vrach, and so he tasked the Genetory with finding the ultimate cure.

Alas, this was not in the cards. Soon after the work on the panacea began, Malcador the Sigillite personally summoned Vrach for a meeting. He admonished the Primarch for conducting extensive genetic research on his flagship without the Emperor's permission, reminding him of the dangers of unrestrained genomancy. By Malcador's decree, the Genetory of the Life Bringers was disbanded, its equipment destroyed and its members demoted to common Apothecaries. Unfortunately, Vrach was already far too obsessed with finding a panacea. After a long period of pondering, he decided to secretly disobey Malcador's orders. While the Genetory was officially culled and its members stripped of their ranks, they secretly received a permission from their Primarch to continue their work. They had to move into half-abandoned old technical decks and settle for what little equipment Vrach could find for them without rousing any suspicion, but they now had his full cooperation. Vrach was determined to go to any lengths to make his noble dream a reality.

As the Great Crusade went on, Sachs plunged deeper and deeper into bioheresy in his desperate quest to find the panacea his Primarch would be satisfied with. Without the rare equipment and unlimited resources he possessed as the master of the Genetory, he found the success rate of his experiments dwindling dramatically. Disillusioned with traditional methods of medicine, he made the hard decision to shed the shackles of medial ethics entirely. Soon, he and his closest adherents experimented eagerly on the kidnapped battle brothers of their own Legion, picking out those who openly stated that the Life Bringers' transformation from a military force to a glorified interstellar hospital was a disgrace to their origins. Valetudinarium became a dangerous place to speak up against the Primarch. And yet, success eluded the Genetors time and again. Constant failure made the once open-minded and curious Sachs into a bitter, callous man who would do anything necessary to bring his research to a successful conclusion. He didn't know yet what exactly was necessary, but he was most determined to find out.
