Gabriel Seth - Blood Angels Conclave: In 999.M41, the Blood Angels teetered on the brink of oblivion following the events on the Shrine World of Sabien. The fate of the Blood Angels Chapter now required the magnanimity of their successors among the Sanguinary Brotherhood. Commander Dante summoned all of the Blood Angels' successors to a conclave on Baal following a near-disastrous Chapter civil war that nearly tore the Blood Angels apart.Dante called for the support of the Sanguinary Brotherhood to help aid the Chapter in the protection of their common primarch's homeworld of Baal as well as the remnants of their Chapter in the face of expected invasions by both the Tyranids and the forces of Chaos. During this time Seth was busy leading a campaign against the Companitas, an anti-Imperial rebel group on the world of Eritaen, when a small Blood Angels envoy brought the summons to the stern Chapter Master.Seth loathed his Chapter's progenitors, hating the fact that the Blood Angels were a First Founding Chapter. He felt that they were both haughty and arrogant by nature, and looked down upon their Successor Chapters with contempt. After arriving at the Blood Angels Conclave on Baal, Seth initially voted against allowing his Chapter to provide Commander Dante with a tithe of initiates like the other Blood Angels successors.While Dante led the discussion at the conclave, the Apothecarion was working on a radical new procedure to replenish the ranks of the Blood Angels in one swift stroke: the lost art of replicae (cloning). Caecus was the Chief Apothecary or Apothecae Majoris of the Blood Angels. Disturbed by the dwindling numbers of his Chapter, and dreading its extinction, he was involved in fruitless experiments, which Commander Dante ordered stopped, to clone Space Marines, thus eliminating the need to go through the arduous process of the maturation and implantation of the gene-seed in an aspirant.However, Caecus disobeyed the order and secretly continued the experiments, prodded by an agent of the Chaos Space Marine Apothecary Fabius Bile. He was tricked into bringing Bile, who was disguised as a well-known Adeptus Mechanicus Magos Biologis, to Baal, mistakenly thinking the false "magos" would help in cloning Space Marines to increase the Blood Angels' numbers.Through Bile's manipulations, Caecus was duped, and only managed to create monstrous, mutant clone Astartes known as "Bloodfiends" who were consumed by the Red Thirst. These creatures were a shattered mirror reformed in the image of a Blood Angel, but lacked any of the qualities that could be thought of as Human. The mutations that cursed the gene-seed of the Blood Angels had been enhanced by the machinations and Chaos tech-heresy of Fabius Bile, and with each drop of blood they consumed, the thirst that dominated the Bloodfiends grew stronger.The mutants broke free from the confines of Caecus' laboratorium and began to run rampant through the sacred halls of the fortress-monastery of the Blood Angels. During their rampage, Bile managed to steal a glass vial that Caeucus had carried back from the Chapel of the Red Grail -- a measure of the mingled blood of a hundred centuries of Sanguinary Priests and Primarch Sanguinius himself, the raw vitae of the Chapter.During the Bloodfiends' rampage, a small group of the bloodthirsty mutants assaulted the sacred chapel of the Chapter's fortress-monastery. One of the Bloodfiends seized the holy relic and then tipped the contents of the cup into its open mouth and drained it to the dregs. Now that the beasts had tasted the blood of the primarch, they only craved more. In the aftermath of this desecration, Bile had achieved his goal and escaped from the Blood Angels' homeworld with a sample of the precious vitae of their primarch to further his vile experiments.The Blood Angels and their successors successfully defended their most sacred of sites on Baal -- the Golden Sarcophagus of Sanguinius within the sacred sepulchre where the Great Angel lay for all time, sleeping in light, forever preserved. The sons of Sanguinius destroyed the horde of mutants and erased the stain of Chaos from their midst.They had paid for the continued sanctity of the Great Angel with their blood, and in the aftermath of this misery, Commander Dante took responsibility for what had happened and accepted it without complaint. Dante believed that it was his hubris that had brought the Chapter to this dark place by authorising the replicae experiments in the first place.The Sanguinary Brotherhood took this into consideration as well as Commander Dante's original request for the successors to grant the Blood Angels a small tithe of their Chapter's initiates in order to replenish the ranks of their primogenitor Chapter. During this defence of the sacred sepulchre, Dante had saved Seth from one of the corrupted mutants. It was only at that moment that he truly realised that all of the Blood Angels successors were truly brothers at heart.The assembled Sanguinary Brotherhood, including the Flesh Tearers, unanimously agreed to hand over to the Blood Angels some of their own neophytes to help their ancestral Chapter rebuild its strength in the wake of the Chaos assault -- and in preparation for the oncoming assaults by the Tyranids and the forces of Chaos.
