Death Cult - Notable Death Cultists: Severina and Sevora Devout - Raised from birth by an ancient sect known as the Emperor's Blades, Severina and Sevora Devout are identical twin sisters who have been taught to wield a blade with astonishing speed, but are unable to read, write or speak. They communicate with an intricate sign language developed by the cult, and, when not actively hunting, they hone the ritual deathblows taught to them by the ancient masters and mistresses of the sect. Inquisitor Gregor Eisenhorn once investigated the Emperor's Blades, but found nothing but puritanical devotion to the God-Emperor. He hired the mysterious twins, taking three solar months to learn their peculiar language. The price he paid? At least one phial of blood from each of the twins' victims must be sent back to the cult's temple to be dedicated to the Emperor. A small price to pay for such lethal talents.Xurris Clorr - Born on a Feral World, this Death Cultist serves the Radical Inquisitor Thaddeus Hakk. She was sent by her master to find and retrieve his previous Acolyte, Interrogator Thirl. The tracker's mission failed, Thirl's prodigious psychic powers granting him full knowledge of the mission and allowing him to ambush his assassins before they even knew of their own doom. Xurris was the lone survivor of the ambush. Despite this, she refuses to acknowledge her failure, and continues to track the heretical Acolyte until she is victorious or dead.Seraph - The assassin known only as "Seraph" is a mind-wiped former Acolyte of Radical Inquisitor Antonia Mesmeron. Seraph knows very little about herself; only a few hints of her past remain before her service to the Inquisitor. What is clear is that Seraph was once a member of the Moritat cult before she was possessed by a sinister Daemon during the Inquisitor's involvement in the Foulmind conspiracy on Protasia. The skills she learned as both an Acolyte and a Death Cultist have made Seraph doubly-feared, and at Inquisitor Mesmeron's side she claimed many lives with her specially-made lathe blades. After her possession, Seraph tore through the depths of Sender Hive on Laskin, weaving a bloody rampage that left no level of Imperial society unstained. Seraph's trail of destruction was halted only by the sacrifice of a squad of Storm Troopers and the personal intervention of Inquisitor Mesmeron, who arranged for a full exorcism of her valued Acolyte. This action was not taken lightly, for Mesmeron intended to use this exorcism to validate her own Oblationist views, and in this, she succeeded. After the exorcism, Seraph became stronger, colder, little more than a tool for her mistress' commands. Those who glimpse the Chaos-brand upon the woman's face find it is usually the last thing they ever see. Recently, Seraph has become more and more battle-hungry, seeking out ever more dangerous foes to fight in her mistress' service. Whether this activity is sanctioned by Inquisitor Mesmeron or a sign of something darker reemerging has yet to become clear.Knosso Prond - Knosso Prond is a member of the Winged Skull Death Cult (see above) who served under the command of the Rogue Trader Elucia Vhane. Prond was forced by the political maneuverings of her cult's governing priestess to take a vow that she would not say another word aloud or return to her temple until she had slain a member from each of 1,000 xenos species deemed to be hostile to Humanity and enemies of the Emperor. Thus, joining Elucia Vhane's Elucidian Starstriders Rogue Trader fleet proved to be an optimal way to begin to make headway on this goal. Though always silent, Prond is loyal to Vhane and acts as her martial champion. When the Chaos God Nurgle's Gellerpox plague struck Elucia's flagship, the New Dawn, Prond was one of the few members  of the crew left uninfected. She now fights besides Vhane to escape from the mutant hordes the supernatural Warp plague has created.Kibellah - Unknown to the Rogue Trader who commands the vessel, a Death Cult lurks within the bowels of House von Valancius' flagship in the Koronus Expanse. For standard years, the ascetic and inscrutable servants of the Death Cult known as the "Bloodspun Web" have protected the dynasty from enemies aboard the vessel, stalking the threats hiding in lower decks and spraying the bulkheads with the blood of their victims. Kibellah is a masterful assassin whose talent and fanatical devotion to the Undying Emperor has earned her the title of the "Second Spinner of the Bloodspun Web." Since childhood, she has dedicated herself to rigorous training of mind and body, perfecting the art of the blade dance and mollifying her emotions. Kibellah has no desires, only duty; no fear, only purpose. She is the perfect instrument of death, and this undying servant of the Undying Emperor has left the shadows to become the Rogue Trader of House von Valancius' personal bodyguard. Her specialised blades and ritualistic arts are at the Lord Captain's service, as is her sophisticated mind. She recognises the divine signs sent by the Emperor, even through the veil of mundane reality. Her world is a realm of riddles and blood that interweave and resolve into momentous insight. To that end, she bears the greatest relic of the cult: a sacred deck of the Emperor's Tarot. The cards speak the will of the Undying One and reveal the names of those who must depart. Every new reading reveals ever more clearly that the greatest moment of her life is at hand. The Immortal Emperor holds an exceptional destiny in store for His servant, who is now ready to step into the future.
