Imperius Reavers - Notable Campaigns: The Cleansing of Praedis-Zeta (645.M39) - In the year 645 of the 39th Millennium, it was a time of great strife and conflict across the galaxy. Four hundred standard years earlier, one of the wealthy families of the Vidar Sector, the Calcerarius of the Darkfall System, saw their power uprooted by an invasion of the most foul kind. The Calcearius clan, led by Februss, fled for their lives to the planet Praedis Zeta, there to seek sanctuary in the coming centuries. It was here that the Calcearius family managed to rise to the upper echelons of Hive Primus, using careful diplomacy to gain the Planetary Governor's favour. Headed by Bijall, ancestor of Februss, the family regained a fraction of their former political power. Some years past, Bijall Calcearius began acting very strangely. Normally a very sly and politically involved man, he had begun to remove himself from diplomatic society and shut himself away in his chambers for solar weeks at a time. Concerned for his health (and the political upheaval his death would cause), Bijall's kin spread the rumour that he had been called away on important family business. In fact, he would spend many solar hours poring over ancient and forbidden texts and conducting his experiments. Rumour spread of these experiments and their heinous biological nature, and before long, infants in his household were being born with an unnatural appearance; hybrids of a most bestial kind. Bijall had changed; he appeared off-colour and some said he could wield the psychic power of the Warp. Suspicions were aroused and the local branch of the Inquisition called for. But before he could be restrained for questioning and tests, he escaped into the Polis region of Hive Primus to continue his vile experiments. The Adeptus Arbites sent out search parties but to no avail -- he had disappeared to continue his work and the children of Polis were doomed to mutation. Word soon reached the Imperius Reavers -- a grave xenos threat had infiltrated Hive Primus; Bijall Calcearius was a vile Genestealer Cult Magus of terrible power and had begun to organically alter the population of Praedis Zeta. Using primitive Tyranid DNA, he had slowly begun to turn the innocent citizens of Hive Primus into hideous Genestealer hybrids -- mindless creatures to serve his will. Hell-bent on the destruction of life on this planet in preparation for the invasion of a Tyranid Hive Fleet, the Bijall Cult was out for blood. With riots on the streets and Imperial authority undermined, there was no time to lose. The Reavers, led by their Chapter Master, Vassile Belousov, quickly mobilised, sending messages to local Imperial allies of the threat. The xenos were to be purged at all costs. The Reavers had fought alongside their Founding Chapter in the First Tyrannic War, and the notion of the genetic abominations created by the Genestealers on Praedis Zeta was abhorrent to the Astartes. They would stop at nothing to clear their home planet of this alien threat and were utterly merciless in their pursuit of their goal. Ultimately, after a brutal and hard-fought campaign and much loss of innocent life, the Imperius Reavers were successful in cleansing their homeworld of the Genestealer taint.
