Blind Io is the current king of the gods. Io means "I see", and in nature he is seemingly an amalgam of Odin and Zeus, with elements of Thor — seen primarily in his use of a number of different hammers (seventy, actually, as detailed by Om). He is completely blind in the traditional sense but instead has countless eyes, which seem to have a mind of their own, orbiting his head. He was eventually compelled to get rid of his raven messengers because of their species' instinctual desire for devouring eyeballs. He lives in Dunmanifestin where he and the other gods play games with the lives of mortals.

Blind Io is a thunder god. Actually, Io is the only thunder god on the Disc. He goes by many names and appearances to make sure he keeps the optimal amount of followers. This is not really unfair because all the other gods use the same trick.

He also has an apparent monopoly on the natural phenomenon of thunder, lightning is allowed for common use by all deities but thunder is strictly regulated.
