Seyfert (セイファート Seifato?) is the god in Tales of Eternia who created the physical worlds of Inferia and Celestia, thereby sealing Nereid's spirit world, Vatenkeist, and creating life itself. Seyfert then sealed Nereid himself in Regulus Knoll 2,000 years prior to the events of the story. Seyfert's teachings say to follow one's own beliefs, even if they mean turning against Seyfert himself.
