Adept Cycerin commanded the outer defenses of the Imperial bastion on Hydra Cordatus, from inside a strike-hardened bunker[1a]. Originally confident in the defenses under his control, he was severely unnerved when these defenses were outflanked and destroyed by an invasion force of the Iron Warriors Chaos Space Marines. As a Chaos Dreadnought hammered its way into the "impregnable" bunker, Cycerin prepared to die bravely, but his life was spared due to the surprise intervention of "The Warsmith"[1b].
The Iron Warriors infected Cycerin with a techno-virus (a variant of the Obliterator Virus) that radically altered his organic and mechanical components, but left him hungry for further change. Cycerin later turned to the Iron Warriors' service, staying loyal to Honsou, who had succeeded the Warsmith[Needs Citation].

By the time of the Bloodborn's invasion of Ultramar, Cycerin had all but given up his humanity, becoming an amalgamation of Dark Mechanicus machinery suspended inside a Chaos-tainted amniotic gel[3a]. This form allowed him to directly interface with Honsou's various war machines, including the flagship Warbreed[3a, 3b] and the Black Basilica command vehicle that Honsou led on Calth[3c, 3d]. From these bases, Cycerin controlled the scrapcode attacks that overwhelmed and shut down the Ultramarines' defenses[3b]. Magos Vianco Locard analyzed these attacks and developed countermeasures, but the raw power at Cycerin's command made the "fight" between him and Locard akin to "a brawny axeman fighting a duellist."[3e] Cycerin was close to overwhelming Locard's defenses and seizing control of the Praetorian Servitors deployed on the Ultramarines' side, before Raven Guard Captain Aethon Shaan infiltrated the Black Basilica and killed Cycerin, shortly before blowing up the entire vehicle with demolition charges[3e].
