The Sapphire King is a Daemon of Slaanesh and noted enemy of the Iron Hands. The Daemon was created from the frustrations of Ferrus Manus at the time of his death as well as the Fulgrim's love for his brother as he slew him.
Leading both Cultists and Emperor's Children, forces worshiping the Sapphire King battled the Iron Hands in both the War for the Ulmetrican Reach and the Skarvus Ambush. The Sapphire King later corrupted much of the Iron Hands, most notably Iron Father Kristos, in the Gaudinian Heresy.[1a] However at the height of the battle, he was beheaded by Iron Hands Epistolary Lydriik.[1b]
