Sisters of Silence - Post-Heresy: Sister-Commander Aphone - Sister-Commander Aphone, alongside her fellow commander Bellas, served as a senior commander of of the Silent Sisterhood during the Indomitus Crusade. After Lord Commander of the Imperium Roboute Guilliman declared an end to the crusade, Aphone was among those Imperial forces that lent their aid to the Realm of Ultramar during the Plague Wars.Sister-Commander Bellas - Sister-Commander Bellas, alongside her fellow commander Aphone, served as a senior commander of of the Silent Sisterhood during the Indomitus Crusade. After Lord Commander of the Imperium Roboute Guilliman declared an end to the crusade, Bellas was among those Imperial forces that lent their aid to the Realm of Ultramar during the Plague Wars. She fought against the vast plague hordes of Nurgle and helped Lord Commander Guilliman reclaim the world of Espandor from the Plague God's clutches.Knight-Abyssal Kavalanera Brassanas - Kavalanera Brassanas was one of the last remaining fifty Sisters of Silence by the mid-32nd Millennium, who lived in exile upon the world of Nadiries. Commanding a Purgatory Squad, Brassanas, like the rest of her order, held utter contempt and disdain towards the Imperium of that time, but nevertheless, was convinced by the "Last Son of Dorn," the Space Marine Koorland, the lone surviving member of the Imperial Fists Chapter, to help aid the Imperium against the deprivations of the Ork WAAAGH! led by the Warlord known as The Beast. During both the Second and Third Battles of Ullanor of that conflict, Knight-Abyssal Brassanas led her squadron in a ritual utilising their innate Pariah Gene to cause a captured Ork psyker to create a "reverse WAAAGH!" effect that slew The Beast.Atarine Hestia - Atarine Hestia was one of the Anathema Psykana, what used to be called a Null-Maiden in ancient times, that served in one of the many isolated enclaves of the fractured Silent Sisterhood upon the world of Arraissa in the last years of the 41st Millennium. Hestia's enclaves was one of those isolated Sisterhoods that still served the Emperor to the best of their abilities, despite their order having long lost their standing amongst the other militant orders of the Imperium and becoming largely ignored and forgotten. Despite this isolation, Hestia was instrumental in providing her enclave with equipment, staff to aid the Sisters in their sacred duties and the necessary tithes and bribes in order to keep the leadership of Arraissa away from their enclave. Despite her primary duties of training new generations of Anathema Psykana, Hestia managed to keep her combat skills finely honed by continuing to hunt down the forces of Chaos. During one such action that occurred during the early years of the 13th Black Crusade, Hestia single-handedly destroyed the Circlet Cult in the shipyards of Eyrainan V. Afterwards, she discovered vital information that led to several other Chaos Cults. In the fifth Terran year of the Black Crusade, Arraissa was invaded by a large force comprised of the notorious Black Legion, which proceeded to eradicate the threat that the Silent Sisterhood posed to them. Her enclave destroyed, one of her disciples, the Witch Seeker Tanau Aleya, who had been off-world at the time of the attack, would later return to the destroyed enclave, searching the ruins for any survivors. Though she did not find any, she refused to believe that her mentor had been killed. Emboldened by her faith in her master's skills, she departed her former home. Later, Hestia would be instrumental in reuniting many of the scattered enclaves of the Silent Sisterhood at the behest of the Adeptus Custodes, and bring them back to Terra, just in time to take part in the Battle of Lion's Gate against a large force of Khornate Daemons.Witchseeker Tanau Aleya - Tanau Aleya was one of the Anathema Psykana, what used to be called a Null-Maiden, that served in one of the many isolated enclaves of the fractured Silent Sisterhood in the last years of the 41st Millennium. During the fifth year of the 13th Black Crusade, Sister Aleya had been sent off-world on a mission to the void station Hellion Quintus to hunt down a Chaos Cultist linked to the Circlet Cult. Killing the cultist, she grabbed a communication device from the dead man's hand, and was immediately seized by dread when she held the malefic device. Displayed upon it was a Heretic Astartes of the nefarious Black Legion who had been communicating with the cultist, and the device repeated the last few seconds of their conversation over and over. Though she could not understand most of the Dark Tongue utilised by the Heretic, one word stood out -- Arraissa. Fearing for her Sisters, Aleya immediately set out for her homeworld. Before departing, she seized a map of the Warp which had been found in the cultist's hideout. Hastening to her enclave enclave's transport ship Cadamara, by the time she arrived, it was already too late, for the Black Legion had already attacked and destroyed her enclave. Aleya searched the ruins for survivors, but found none. While searching, she discovered the room of the enclave's Astropath Lokk, who had scrawled a final message on a wall with his own blood that read, "He calls his daughters home." Departing her former homeworld, Aleya pondered the meaning of the message and came to the realization that the message was a call for the Silent Sisterhood to return to Terra, to fight on behalf of the Emperor once again. Aleya then made the perilous journey back to Terra. During her journey through the tumultuous currents of the Immaterium, Aleya was forced to drop out of the Warp and back into realspace due to the damage sustained to her vessel and the negation of the Astronomican following the formation of the Great Rift. Stranded and alone, only through sheer happenstance did she encounter a Black Ship controlled by a Custodian who had been sent by Terra to bring the various enclaves of the Silent Sisterhood back to Terra. She would later be reunited with her mentor, Atarine Hestia, and be brought to Terra, and later take part in the Battle of Lion's Gate. During this conflict, she encountered the Custodian Valerian and the two fought side-by-side against a Bloodthirster, a Greater Daemon of Khorne, and managed to vanquish the beast. Following the end of this conflict, Aleya still yearned for vengeance against the Black Legion for the destruction of her homeworld. Utilising the captured Warp map, she and her companions were able to set a course to engage the Heretic forces. Not wishing to see his friend killed, Valerian agreed to accompany the Sister of Silence alongside 40 other Sisters and several Custodians aboard a Black Ship. Utilising the Warp map, they were able to track the Black Legion to the Imperial world of Vorlese, which was already under assault. The Heretic Astartes were attempting to drop a shard of a Cadian Pylon onto the planet's surface in order to shut down Warp travel within the area and further isolate Terra from the rest of the galaxy. Both Aleya and Valerian led a boarding operation of a Chaos Grand Cruiser at the centre of the assault. Fighting a desperate last stand against the superior force of Heretic Astartes, they managed to prevent the shard from being dropped upon the world. However, the majority of the Imperial forces were slain, with the exception of Aleya, Valerian and one other Custodian, though all were sorely wounded. Fortunately, Roboute Guilliman's Indomitus Crusade fleet arrived and helped to defeat the Black Legion. Guilliman captured the Grand Cruiser and encountered Aleya and her companions, who were all unconscious and all were rushed to immediate medical care.
