Elesh Norn is one of the main antagonists of the Magic: The Gathering block Scars of Mirrodin and, ultimately, one of the main antagonists of the overall recent story arc, as she became the dominant praetor of New Phyrexia. Part of Phyrexia, a horrifying biomechanical menace that is equal parts civilization of metal and necrotic flesh, and infection that spreads and engulfs all life, she came into being when the world of Mirrodin fell to its corruption, rising as the praetor (i.e. "lord") of the New Phyrexia faction known as The Machine Orthodoxy, aligned with White mana.
