One of my three favorites, Storyteller Umi.

He just might become a JOAT. Probably not, but I hope so.
Here's his history:
Umi was born to the original tribe, like Bico and Ponui. He came from a line of builders, and married the chief-to-be, Pari. The year after their marriage, Pari became the chief. Months later, she had a child. That was about when the marriage of the nature prince and princess was held. Everything went wrong from there. After two parts of the tribe left, most of the remaining villagers became sick. Umi was one of the few that left in search of a cure. He had to leave his wife, who became the adopted mother of Ponui, to find a cure. He returned to give the survivors the cure and the news that the others might not return. He stayed, finding that Pari, the only reason he worked so hard for, had died.
