Blood Ravens - Chapter Homeworld: Early in their history, the Blood Ravens maintained their fortress-monastery at Selenon, within view of the hive city of the same name on the Hive World of Aurelia in the Sub-sector Aurelia of the Segmentum Ultima's Korianis Sector. It was a technologically advanced and profitable world that served as the economic heart of the region, and the proud namesake of the entire sub-sector.In the late 40th Millennium, however, a Warp storm suddenly engulfed the planet, summoned by the Great Unclean One Ulkair in his battle against the Blood Ravens. The Blood Ravens' then-Chapter Master Moriah and Librarian Azariah Kyras sealed the Greater Daemon of Nurgle within the heart of the planet, but the damage was done.Aurelia disappeared into the Warp, and remained there for almost a standard millennium, transformed into a perpetually-shifting Ice World devoid of all life save for Daemons and other Warp entities. With the loss of Aurelia, the Blood Ravens were transformed into a fleet-based Chapter who recruited their aspirants from the other populated worlds in the Aurelian Sub-sector.As a fleet-based Chapter, the Blood Ravens now have no official homeworld. Instead, their fortress-monastery is situated onboard the massive battle barge Omnis Arcanum, which is also home to their precious Librarium Sanctorum. The rest of the Chapter serves aboard the unusually large fleet of strike cruisers and other battle barges that were assigned to the Blood Ravens long ago when the Chapter was founded.Most of the Blood Ravens' neophytes come from the major worlds of the Sub-sector Aurelia, including the desert Feudal World of Calderis, the jungle Feral World of Typhon Primaris and the nearby Hive World of Meridian, but none of the recruits from Meridian had passed the Blood Trials to become Blood Ravens neophytes in several standard centuries.Thaddeus is the first Blood Raven Astartes to come from Meridian in several centuries, having been recruited from the hiver street gangs he led there by Captain Davian Thule. It is repeatedly said that the loss of Calderis would cripple and eventually kill the Blood Ravens Chapter as they had no other way to recruit neophytes, and the defence of Sub-sector Aurelia from the Tyranid splinter hive fleet was considered important enough to mobilise both the Blood Ravens' 3rd and 4th Companies.The 3rd Company of the Blood Ravens commonly sought aspirants from the planet of Cyrene (also in Sub-sector Aurelia) until then-Captain Gabriel Angelos had it destroyed with an Exterminatus order. The taint of Chaos had been found in the planet's population, a taint so terrible that only Exterminatus could prevent the contagion from spreading to other Imperial worlds in the region.Aurelia made an ominous return to realspace in the 41st Millennium, a thousand Terran years after it was lost. This re-emergence was orchestrated by the Black Legion, and it was only by the heroics of the 3rd and 5th Companies that their plans to devastate Sub-sector Aurelia were thwarted. What was left of Aurelia remains in realspace to this day and is heavily monitored by both the Blood Ravens and the Inquisition and is garrisoned by regiments of the Astra Militarum.While the Blood Ravens now have no fixed base of operations, the other worlds of the Aurelia sub-sector continue to provide the majority of the Chapter's recruits and much of its wargear. There are a number of worlds in particular that the Blood Ravens favour over others. Why this should be the case is not fully understood, but it is speculated by some that these worlds have a higher incidence of psykers than normal. Though such speculation is not fully substantiated, the Chapter's prevalence of Librarians lends such ideas credence.The Blood Ravens, like many fleet-based Chapters, recruit from a number of different worlds. However, the class of worlds they recruit from is not limited, and they draw initiates from Feral Worlds and Hive Worlds alike. The only similarity between the worlds is the higher volume of psykers they are home to, leading to an increased number of Librarians in the Chapter. However recent events have seen the Blood Ravens lose many of these recruiting worlds. The known Blood Ravens recruiting worlds and their status are as follows:Calderis - Calderis is a Desert World sparsely populated by wandering bands of nomadic Humans. These hardy peoples used to provide recruits to the Blood Ravens but the WAAAGH! of Warboss Gorgrim drove the Feral Orks on the planet to sweep across the sands in a tidal wave of destruction. Only a scant few of the planet's inhabitants escaped aboard chartered voidcraft or with the Blood Ravens. The rest were left to die horribly and violently to the Orks. As with Typhon Primaris, it is unclear what will be done with Calderis. When Gorgrim has gathered enough Ork Boyz he will move on, leaving the world barren, the Feral Ork populace decimated and the Humans gone, having either fled or died. The planet might be re-colonised by the Imperium at some point but the culture of Calderis and the majority of its people are no more.Cyrene - An old recruiting world of the Chapter, Cyrene is located in the Aurelia Sub-sector but was cleansed by an Exterminatus action when Captain Gabriel Angelos discovered a Chaos taint on the planet and requested an Inquisitorial purge. The exact nature of the taint and the reasons Angelos deemed Exterminatus necessary, are, like many things with the Blood Ravens, a mystery.Meridian - The Hive World of Meridian is the capital world of the Aurelian Sub-sector and now the only populated world of the sub-sector as well, since Cyrene, Calderis and Typhon Primaris were cleansed of all life by the actions of the forces of Chaos, the Orks and Tyranids, respectively. Meridian itself came perilously close to succumbing to the Tyranids as well. Only the miraculous arrival of Captain Gabriel Angelos and the Blood Ravens' 3rd and 9th Companies stopped the Tyranids from overrunning the planet. The initial defenders under Sergeant Aramus were nearly wiped out during that campaign. However, Meridian is only a marginal Blood Ravens recruiting world, as the first recruits it had provided in centuries to the Chapter were Sergeant Thaddeus and Sergeant Aramus. However, Sergeant Thaddeus did locate two likely young boys during his mission deep behind Tyranid lines and they have since shown promise as aspirants for the Chapter. By the time of the Third Aurelian Crusade, much of Meridian had been devastated by the successive Tyranid and Chaos Space Marine invasions, and the destruction of the Capital Spire had annihilated the planetary government. Whether the world will recover in the wake of the end of the conflicts in the Aurelian Sub-sector remains to be seen.Rahe's Paradise - Rahe's Paradise is yet another recruiting world of the Blood Ravens to have been lost recently, the planet having been discovered to be an ancient Necron Tomb World. The Blood Ravens' campaign against the Necrons and the Craftworld Aeldari on the planet cost them dearly but did result in the recruitment of a handful of initiates to the Chapter, though the world is now lost and will provide no more new warriors.Trontiux III - Trontiux III was one of the Chapter's remaining principle recruiting worlds. Trontiux III was recently visited by the Litany of Fury following the Tartarus Campaign.Typhon Primaris - Another of the 4 inhabited worlds in the Aurelia Sub-sector, Typhon Primaris was a Jungle World that provided feral but strong recruits to the Chapter. However when Tyranids invaded the sub-sector their taint reached Typhon Primaris quickly and festered in the depths of the jungles unnoticed. By the time the Blood Ravens arrived, the planet was in the final stages of Tyranid bio-consumption and saving the world was no longer a realistic option, though the Blood Ravens did succeeded at finally defeating the splinter of Hive Fleet Leviathan that had assaulted the Aurelian Sub-sector. The Second and Third Aurelian Crusades saw extensive fighting take place between the Blood Ravens and their allies amongst the [[Astra Militarum] against Chaos Space Marine, Ork, Craftworld Aeldari and surviving Tyranid forces on this benighted world. Finally, during the Third Aurelian Crusade, the entire planet was subjected to an Exterminatus on the orders of the Inquisition, killing millions.
