Sons of Medusa - Notable Sons of Medusa: Iron Father Setol Sollex - Setol Sollex was an infamous Omnissian mystic, formerly of the Iron Hands Chapter. During the early 35th Millennium a new heretical doctrine began to spread like wildfire within the ranks of the Adeptus Mechanicus, eventually transmitting further afield to the Space Marine Chapters with close ties to the Cult Mechanicus. Known as the Moirae Schism, this heretical doctrine was the most widespread and bitterly contested within the Mechanicus since the Horus Heresy and the birth of the Dark Mechanicum and its Chaos tech-heresy. When these radical teachings reached the Iron Hands, there was a great dissension within the ranks of the Chapter. The tenets of the Moirae Schism were championed by Iron Father Sollex amongst the Chapter's clan companies. Internecine conflict was only avoided by the last minute intervention of the Iron Hands Great Clan Council. Their proposed settlement was exile for the minority of those within the Chapter who had embraced the dissident doctrine, and a binding treaty never to raise their hands against their former brothers. Fully a third of the Iron Hands brethren departed, to be joined by a handful of Astartes from other Iron Hands Successor Chapters who shared their divergent beliefs. Led by Iron Father Sollex, despite their exile from their parent Chapter, the Moirae exiles continued to seek out and fight the enemies of the Imperium, believing themselves to be the true Iron Hands.Mazos Dhule, Iron Thane of the Atropos War Clan - Mazos Dhule was an iron thane of the Atropos War Clan. He is known for trusting automata-weapons more than any mortal ally in battle, as they will not succumb to fear and will not retreat, just like the Astartes of his Chapter. He led the Atropos War Clan in the Galen VI subjugation campaign during the Badab War.Morn Graevarr, Iron Thane of the Atropos War Clan, High Artificer of the Sons of Medusa - Morn is the current iron thane and high artificer of the Atropos War Clan, its leader and master weaponsmith. He took part in the Badab War, during which he suffered the loss of his left arm and its replacement with an augmetic limb. Graevarr later crossed the Rubicon Primaris to become a Primaris Space Marine once the Sons of Medusa gained Primaris technology during the Indomitus Crusade.Vaylund Cal, Iron Thane of the Atropos War Clan, High Artificer of the Sons of Medusa - The undisputed master of the Atropos War Clan of the Sons of Medusa, Vaylund Cal is an iron thane of the Chapter, serving in a dual role as his War Clan's master weaponsmith and war leader. He was considered to be a soullessly cold and emotionless figure, made all the more imposing in his hulking black and emerald power armour. A fanatic believer in the teachings of the Moirae Sect of the Cult Mechanicus, Cal is renowned for employing Devastator Squads with extremely high levels of deliberate cybernetic augmetics in his clan's forces. Vaylund Cal's own largely cybernetic body is a testament to his life's work in the service of the Machine God and what little remained of his organic tissue was shot through with bionic and auto-sanguinary systems that increased his strength and endurance beyond even the superhuman levels of the standard Astartes. During the Badab War, the inhuman Vaylund Cal and the Sons of Medusa were treated with suspicion and barely concealed contempt by their fellow Loyalists for their Chapter's widespread deviation from the tenets of the Codex Astartes and because it was believed by many of their fellow Astartes that they had ulterior and dark motives for their part in the war. The Sons of Medusa joined the Loyalist cause in the Badab War in direct response to Legate Inquisitor Jarndyce Frain's call for Space Marine re-enforcements after the Secession of the Astral Claws had been declared heretical. The Sons of Medusa's stated reason for participation in the war was the punishment of the Renegade Astral Claws and the other Secessionist Chapters whom they viewed as having earned retribution for their betrayal of the Emperor's trust. Although Iron Thane Valund Cal deferred to the Magister Militum (supreme commander) of the Loyalist war effort, Lord High Commander Carab Culln of the Red Scorpions, in strategic deployment and the operational tasking of his Chapter, no Sons of Medusa answered to the orders of any but their own Chapter superiors at the tactical level. Culln had fought alongside the Sons of Medusa before during the defeat of WAAAGH! Skullcleava thirty years previously and knew them well, whilst the Red Scorpions also earned the Sons of Medusa's respect as a Chapter and this helped to maintain amicable relations within the Loyalist camp. This prior history allowed Culln and Cal to pursue a smooth working relationship when they might otherwise have been in discord due to their disparate natures, and Culln wisely deployed the Sons of Medusa only where their strengths and tenacity would prove most advantageous to the Loyalist cause. The Sons of Medusa most famously conducted the subjugation campaign against the rebel world of Galen. The last major engagement the Sons of Medusa took part in was the hard-fought assault on the orbital fortress of Sentinel-Sigma in preparation for the final Loyalist attack on Badab Primaris. It was Vaylund Cal at the head of the Atropos Terminators who fought his way to the star fortress' main engine vaults and severed the five-metre-thick plasma couplings to silence the station's guns, allowing the Loyalists free rein to attack the station's surface. The eventual conquest of Sentinel-Sigma shattered the Badab System's vaunted "Ring of Steel" defences and allowed the final assault on Badab Primaris itself to begin. Cal crossed the Rubicon Primaris to become a Primaris Marine some time after the birth of the Great Rift. He is now accompanied into battle by Aggressor Squad Kolgrimm, who serve as his stalwart bodyguards and his faithful servitor M0RTI5, who carries the iron thane's Omnisian Axe into battle.Deathwatch Watch Captain Mathias - For two standard centuries, Watch Captain Mathias has served the Deathwatch. From the battlefields of the Orpheus Salient to the dusty halls of long-lost Watch Stations, Mathias has devoted his service to the tenets of the Deathwatch and their guardianship of the Jericho Reach. Mathias came to the Deathwatch for what was to be only a decade-long assignment. Early during his tenure with the Long Watch, Mathias was assigned to guard Inquisitor Ramaeus during a tense encounter with a group of Craftworld Aeldari said to have valuable information about the so-called Dark Pattern -- a series of mysterious events that continue to unfold within the Jericho Reach, presaged in numerous ancient prophecies foretelling of great strife and darkness coming to pass in that area of space. The recently-seconded battle-brother found himself fascinated by the enigmatic Inquisitor and her mysterious prophecies and after this encounter he devoted a great deal of time to studying all he could learn about them. The interest that Mathias displayed in researching the Dark Pattern drew the attention of Inquisitor Ramaeus, who approached the Space Marine and asked him to join her in her pursuit of answers. He has since joined a handful of like-minded, inquisitive Deathwatch Space Marines who have been drawn back to the study of nearly-deserted Watch Stations, now known as the Dead Stations, and the ancient traces of knowledge and prophecy they contained. These few members have since dedicated their lives to finally unravelling the enigma of the Jericho Reach. Thanks to their interest in the Dead Stations, their peers refer to them as the "Dead Cabal". After joining the Dead Cabal, Mathias quickly rose through the ranks of the Deathwatch, earning the rank of Watch Captain in only twenty years. He distinguished himself on the field of battle against all manner of xenos throughout the Jericho Reach. As one of the highest-ranking members of the Dead Cabal, Mathias has repeatedly used his influence and position to assist other members in securing artefacts and knowledge that the Inquisition and senior Deathwatch commanders would sooner see suppressed. He values this knowledge above any politics and despite any ill will he has gained, he remains a champion for the work of the Dead Cabal.Orros Naehr -  Lieutenant of the Atropos War Clan.Uhllkar Noxyn - Lieutenant of the Atropos War Clan.Xeriis the Unrelenting (Redemptor Dreadnought) - Xeriss is a Redemptor Dreadnought of the Atropos War Clan.Deathwatch Battle-Brother Theclus - A taciturn battle-brother of the Sons of Medusa Chapter, Theclus was known to have been undertaking his second vigil of the Long Watch when chosen to fight alongside Watch Captain Aesalon. His battle honours during his first vigil are etched in the stone of the Hall of Glory on Watch Fortress Erioch and include battles against several xenos species entirely unknown to the Imperium in the 41st Millennium. The deed for which Brother Theclus is most well known is, of course, his survival against the first attack of the Lord of Lightning, a feat that is recorded in numerous tomes and still recounted from the pulpits of the watch fortress.Ancient Maarkol Dourr - Maarkol Dourr is a Primaris Ancient of the Atropos War Clan.
