Sisters of Silence - Horus Heresy Era: Knight-Commander Jenetia Krole - Jenetia Krole, known also in popular myth as the "Soulless Queen," was the mistress of the Raptor Guard and one of the Emperor's personal battle confidantes, as well as the highest-ranking Sister of Silence during the early days of the Horus Heresy. One of the most sinisterly renowned warriors in the Imperium, Jenetia Krole was one of the most mysterious and feared warlords of the Imperium. The foremost battle leader of her Order, Jenetia Krole stalked the shadows of the Great Crusade at the behest of her master, the Emperor. She commanded whole armies, who sought out and slew psykers turned would-be gods, and cut the lives short of those who aimed either to subvert or deny the Great Tithe, and brought down blood retribution on any who slew those of her Sisterhood.Mistress of the Black Ships Varonika Sulath - Varonika Sulath was responsible for the execution of the Great Tithe of psykers and held the rank of Mistress of the Black Ships, and in effect was the grand admiral of the Divisio Investigates ' fleet during the Great Crusade and Horus Heresy eras. During the Webway War, Sulath oversaw the decree known as the Unspoken Sanction by direct order of the Emperor. This decree involved the accelerated gathering of psykers throughout the Imperium to sacrifice themselves in order to power the Golden Throne long enough for the Emperor to leave it without risking the collapse of the protections surrounding the Imperial Webway, so that he could safely take part in fighting the forces of Chaos within its confines.Nemesis Praxia Ebon Naroda - Ebon Naroda served as the high guardian of the compiled lore and estates temporal of the Divisio Investigates, and ultimately was responsible for the training of its acolytes during the Great Crusade and Horus Heresy eras.Sister-Senior Celia Harroda – Sister-Senior Celia was the Witchseeker Pursuivant, a heroine of the Sisters of Silence during the Siege of Terra, when there was a massive Daemonic incursion within the Imperial Webway created by the Emperor in the subterranean levels of the Imperial Palace. On one occasion a mighty Bloodthirster, the greatest of the Daemons of Khorne, fought its way through the Imperial defenders and to the Webway gate into the Palace itself. Only the last minute intervention of Sister Celia Harroda was able to stop the beast from crashing through the gate and into the Imperial Palace's dungeons. Sister Celia confronted the huge Daemon, her presence chilling the air around it and stifling its otherworldly power, and silently she despatched the monster with swift strokes from her blade of frost. The effort utterly exhausted her and with the final, banishing stroke of her greatsword she collapsed upon the threshold between the Warp and realspace, never to take another breath.Sister-Senior Gresselda Vym - A Witchseeker Pursuviant during the Horus Heresy, Vym commanded the Black Ship Somnus and the Brazen Sabre Cadre on a mission to the world of Drusilla to capture the Rogue Psyker Xalmaguni. During this mission her craft was shot down by the Alpha Legion. Her whereabouts after this tragic event remains unknown.Sister Emrilia Herkaaze – Sister Herkaaze was an Oblivion Knight of the Silent Sisters. Alongside Amendera Kendel, Sister Herkaaze was drawn to the notice of the Sisters of Silence as a child. Each of these Sisters were recruited from worlds in the Belladone Reach. Kendel and Herkaaze had shared a vague kinship throughout their Aspirant trials, but as they had grown into full Sisterhood, the women's early friendship soured. Years later, they were bitter rivals within the order, each nursing antipathy for the other. How this bitter enmity began is not truly known, but one story, told to novices by other novices, said that the women had once fought with a fire-witch on Sheol Trinus; Herkaaze, unwilling to fall back before a powerful enemy and regroup, had been struck by burning debris and later turned the blame upon Kendel for refusing to support her. Sister Emrilia's extensive old wounds might indicate that there was indeed some truth to this tale. She would later break her vow of silence before Amendera Kendel and stated that the Horus Heresy was happening because the God-Emperor wished for it to happen.Sister Kaeria Casryn - Casryn was an Oblivion Knight of the Steel Fox Cadre of Vigilators during the Horus Heresy. During the War Within the Webway, Sister Kaeria was paired with the Custodian Diocletian Coros. During this conflict, the two formed a strong bond and grew to become close comrades. Coros had fought alongside the Silent Sisters for several solar decades and was able to understand Kaeria's meaning by simple facial expressions without having to sign to him in Thoughtmark. As a result, Sister Casryn eventually accompanied the Custodian outside the Imperial Webway as they attempted to recruit reinforcements for this clandestine war. Later on, Sister Casryn would help implement the Unspoken Sanction as decreed by the Emperor, as she oversaw the sacrifice of a thousand captured psykers in order to power the Golden Throne long enough for the Emperor to leave it for a single solar day, to help bring the War Within the Webway to a successful conclusion. During the Siege of Terra, Casryn was one of those chosen to come before Malcador the Sigillite before he ascended the Golden Throne and carry out the final tasks he gave to them before his death. At his command she gathered captive psykers to sacrifice to the Golden Throne once more to aid Malcador in his struggle to power the ancient device while the Emperor confronted Horus upon the Vengeful Spirit.Sister Amendera Kendel – At the outset of the Horus Heresy, Amendera Kendel was thirty standard years old and, like her fellow sisters, cut an impressive figure; she was lithe and poised, clad in a shimmering snakeskin over-suit of dense mail and a sweep of golden armour plate that resembled a bodice. She wore her purple-black coloured hair in a topknot from a seamless scalp, bare but for a blood-red tattoo of the Imperial Aquila. Sister Kendel was an Oblivion Knight and commanded the Black Ship Aeria Gloris. During the Great Crusade Sister Kendel was a part of a cadre of Sisters sent on the orders of Malcador the Sigillite to deploy alongside the Death Guard Legion in the prosecution of the xenos known as the Jorgall for daring to venture into human space. The Sisters proved instrumental in attacking and wounding a powerful mutant Jorgall psyker. They then captured the wounded creature for transport back to Terra and further research into its abilities. Sister Kendel then moved on to perform other duties. After the opening shots of the Horus Heresy occurred on Istvaan III, Sister Kendel volunteered to protect the Death Guard Captain Nathaniel Garro and the survivors of the frigate Eisenstein at the Somnus Citadel on Luna. She was later forced to lead her fellow Sisters into battle with the corrupted Death Guard Astartes Solun Decius who had finally given into the Nurgleite contagion inflicted upon him by the reanimated corpses aboard the Eisenstein. His corrupted body had mutated into a daemonic entity known as the Lord of the Flies. After defeating this potent daemonic threat, Sister Kendel, Captain Garro and Captain Iacton Qruze of the Luna Wolves were confronted by Malcador the Sigillite. The Regent of Terra informed them of his intentions to form a new organisation which would need to utilise "men and women of an inquisitive nature" and offered them a place within this new fellowship of Loyalists, even promoting her to the rank of Agentia Tertius. While Amendera Kendel's ultimate fate remains unknown, she has entered Imperial history as the first mere human to order the ultimate sanction of Exterminatus carried out on the treacherous world of Proxima Majoris.Sister Thessaly Nortor – An Oblivion Knight, Sister Nortor possessed a taut, scar-sharpened face which was usually drawn down into a scowl. The second-in-command of the Storm Dagger cadre had made no secret of her disdainful opinions of the Warmaster Horus' mutiny against his father the Emperor. Sister Nortor's breath would rasp quietly through the mechanical apparatus at her neck; almost three-quarters of Nortor's throat had been replaced with a mechanical augment. Made of a polished silver-steel, her cybernetic implant served the function of flesh destroyed during an engagement against the Jorgalli, inside one of the xenos' bottle-worlds. As well as her neck, much of the Null Maiden's lungs were also synthetic proxies assembled by the Sisterhood's biologians. Many of her fellow Sisters were privately envious of the dour Sister Thessaly; Nortor's larynx had been lost to the acidic bite of the bottle-world's alien atmosphere, and she had refused to allow her augmentation to be fitted with an artificial replacement for her missing vocal cords. The woman was as silent as was humanly possible, and therefore an ideal to be emulated by her fellows within the order.Melaena Verdath - Melaena Verdath was a Silent Judge serving as part of the Silent Sisterhood's Excruciatis, the de facto secret police that acted as investigators and hunters to root out and hunt down both hidden psykers and those who harboured them. Her treatise, the Voiceless Judgments, were studied by later Acolytes of the Sisterhood.Leilani Mollitas - Novice-Sister Leilani Mollitas served as a Sister-in-Waiting to Oblivion Knight Amendera Keel during the early years of the Horus Heresy.
