God of Phyrexia

Orsaga's offer to lend a hand had not merely been empty words.

When those red snakes originating from him were unconsciously fused by Yogmoth,

Orsaga's will became like an invisible, formless hand—a virus that had breached the source code's defenses—and embedded itself directly into Yogmoth's soul and body.

Just when everyone believed this was a sign
