- Scions of Sanguinius Conclave (999.M41) - Teetering 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 Successor Chapters. Lord Commander Dante summoned all of the Blood Angels' Successor Chapters for a conclave on Baal following the near-disastrous Chapter civil war that nearly tore the Blood Angels apart. Dante called for the support of the Blood Angels Successors to help aid the Chapter in the protection of their common Primarch's homeworld and his remains from the attack of both the Tyranids and the Forces of Chaos. While Dante lead the discussion at the conclave, the Apothecaria was working on a radical new procedure to replenish the ranks of the Blood Angels in one swift stroke: the lost art of replicae. 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 Lord 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 vile 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 Chaotic 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. The Blood Legion, along with the Blood Angels and their fellow Successors successfully defended their most sacred of sites on Baal -- the Golden Sarcophagus of Primarch 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, Lord Commander Dante took responsibility for what had happened and he accepted it without complaint. Dante believed that it was his hubris that had brought the Chapter to this dark place. The Successor Chapters took this into consideration as well as Lord 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 the Chapter. The Successor Chapters 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 assault by the Tyranids and the Forces of Chaos.
