An immortal who's blood appears to be mercury. He is pale with black bird wings and black hair with silver highlights. He is often happy, but wears a sad smile.
I'os is very wise and kind. He enjoys talking with people and learning there stories, as well as relating his own.
I'os does not use much in the ways of weapons, relying on his magic to get him through in a pinch. He uses his wings, who's feathers are hard as steel, for defense, flight, and even offense, as the feathers are sharp.
I'os is old, very old, and is kind as a result of seeing the world, or worlds rather.
