===The Battle of Rai===
{{Main|Battle of Rai}}

The Battle of Rai was the final major confrontation of the Scouring the Life Bringers took part in. The Legion was chased by the combined forces of the [[Entombed]] and the [[Void Angels]] back to their homeworld of Rai, which Vrach intended to turn into a death trap for his pursuers. By this point, half of the Life Bringers consisted of Plague Marines and another half of plantmen, and Sachs was in charge of the former group. At the order of his Primarch, he was dispatched to deal with the Entombed forces on Rai. Although they were dramatically outnumbered, the children of Golgothos managed to fight their way into the midst of the Plague Marine ranks, after which their leader, Cardinal Merik, released a Shard of the Nightbringer that he likely obtained on some Tomb World. To deal with this new threat, Sachs had to sacrifice his own reserves to Nurgle in exchange for summoning a Great Unclean One. But even direct assistance from his god didn't help him much, as the plantmen of Nikephoros Galen cravenly ran away, leaving Sachs to deal with two Legions at once. Unable to win this fight, High Genetor made the decision to evacuate. 

After their ignoble escape from Rai, it was Sachs who advised his Primarch to seek refuge in the Eye of Terror. Left with no other sensible options, Vrach agreed to his suggestion, and the Life Bringers followed the rest of the Traitor Legions into the rift where the Warp spilled into reality. The Legion quickly found a suitable Daemon World for itself, which the Primarch named Eden. Alas, his reign over his new domain proved to be short-lived, as Nurlge decided to finally reward his servant for his loyalty and granted him Daemonhood. As most Daemon Primarchs, Johannes Vrach showed very little interest in actually running his Legion, leaving Sachs in charge. Many of the Heresy veterans challenged his superiority, aspiring to seize the leadership for themselves. These dissenters were dealt with swiftly and brutally, leading to a further splintering of the Life Bringers. But Sachs didn't really care for the well-being for the Legion: for the first time in forever, he was free to research and experiment as much as he wished to.
