Mammetum, the Visage of Transfiguration is one of the Apocalyptic Forms avaliable to the Fallen, specifically those of the House of Lammasu. The Mammetum, for all their gifts, appear as oddly formless beings themselves. They seem to constantly shift their features, and many leave after-images of themselves as they move. Others take the opposite route by assuming an androgynous appearance, void of identifying or unique features. The High-Torment Mammetum are not nearly as fluid; their transformations are almost painful to watch and they tend manifest their hatred directly on their bodies in the form of claws, sharp teeth, or other monstrous appendages.
