He is a creator deity who once wandered the Earth. Presumably he created everything and kick-started the world, but so far we only know that he apparently made water spring from under the ground to help creatures survive.
It appears he is rather a long-haired deity as he was able to lower one of his hairs all the way down to Earth for the WAPIYA girls to climb. What he did with them after that is a bit of a mystery to us. They all disappeared from the planet and never even sent a postcard.
