Wars of Flesh
From Warhammer 40k - Lexicanum
The Wars of Flesh was a conflict initiated by the Iron Warriors inside the Eye of Terror.[1]
The transmogrifying plague known as the Technovirus spreads from Medrengard’s across the worlds of the Eye of Terror. It infects metal construct and human flesh alike, turning one to the other and blending warriors with their weapons and wargear until only machine-things remain. After a series of vicious conflicts, the nihilistic Cult of Destruction expands massively. Obliterators and Mutilators join the ranks of the Iron Warriors in ever greater numbers.[1]
