At the time of the Battle of Calth, he served as a Captain of the Ultramarines Legion's 6th Company. His company's sigil was that of a serpent coiled into a figure-eight shape. Following the sundering of the Legiones Astartes into separate Chapters during the Second Founding, he was anointed as the first Chapter Master of the newly created Iron Snakes Chapter. The new Chapter's badge was also a coiled serpent and one of its most notable Tactical Squads was named Damocles in honour of the Chapter's founder.Chapter Master Seydon - Seydon is the Iron Snakes' current Chapter Master.Chief Librarian Petrok - The Iron Snakes' current chief librarian.Chief Librarian Nestor (Deceased) - The Iron Snakes former chief librarian, and mentor to Petrok.Hero-Captain Phobor - Phobor is a hero-captain (Veteran officer) of the Chapter.Captain Cules - Cules is a captain of the Chapter and commanded the Iron Snakes forces deployed during the Sabbat Worlds Crusade.Captain Didymos - Didymos is a captain of the Chapter.Captain Pheus - Pheus is a captain of the Chapter.Captain Skander - Captain Skander of Phocis Squad became possessed by a vile Daemon after it fled the body of the dying brother Krates.

On the world of Cozan, Ridates Squad came up against a Daemon, who haunted them and directed its minions against them. Ridates Squad was caught in a deadly crossfire with the forces of Chaos in a gully and the entire squad was decimated in less than six minutes. Through sheer chance, only Apothecary Khiron survived when a stray round brought down the rocky wall of the gully, burying him in rubble. As Khiron lay buried and unconscious, the Daemon passed over him, believing that he was dead. This encounter left Khiron with knowledge of the vile creature's unforgettable smell. When Khiron finally emerged from the rubble, all he could do was recover the Progenoid Glands from the bodies of his fellow battle-brothers. Thebes Squad later overran the Daemon's minions, but the creature fled and hid within the wounded body of Brother Krates. Blinded by the Daemon's malefic powers, Thebes Squad brought Brother Krates back to their fortress-monastery on Karybdis. But Khiron recognised the Daemon's signature smell, and immediately set upon Krates with his bolter, slaying him. His fellow battle-brothers were horrified, thinking Khiron had lost his mind to the taint of Chaos, and jailed him in the Tholos beneath the Chapter House. While incarcerated, Khiron reflected on recent events and quickly realised that he had in fact not killed the Daemon, since he had used a Bolter instead of cleansing flame, and that the Daemon must have moved on to possess another host body. Unfortunately, his brothers would not listen to his claims. When Damocles Squad returned to Karybdis, Sergeant Priad requested Khiron as a replacement Apothecary for his squad's own deceased Apothecary, Memnes, and was subsequently denied. Priad then went to visit Khiron in the Tholos to investigate the stories of his madness. Khiron warned Priad of the Daemon, and informed him that he had asked for the ritual of Oethanar in two sunsets. Later, Priad sensed the peculiar, signature smell of the foul Daemon in Captain Skander of Phocis Squad during a combat drill and attacked him. Sergeant Priad eventually killed both the possessed captain and the Daemon with a Flamer. Priad then embarked with Damocles Squad to the Primarch's Causeway on Ithaka to rescue Khiron from the Oethanar. They barely managed to reach Khiron before the Wyrms could devour him. Having been vindicated for his actions, Khiron was later reinstated as Damocles Squad's Apothecary.Sergeant Raphon - Raphon was the commander of Damocles Squad until the Undertaking on Rosetta.
