Ogurien is a fay descended from the legendary Fomorians, a semi-divine race of giants who guided the forces of nature in ancient times. At an unknown time, he became ruler of Avalon isle, married a Norman woman, and sired Guinevere. Ogurien's screentime is brief, so most of his personality is underdeveloped, but he seems to have been a benevolent king, much beloved by his subjects.
A hundred years ago, when Avalon was at peace, Ogurien was a rugged yet handsome giant standing at fifteen feet tall. He had green eyes, and bright red, wild hair and a thick beard, both of which were braided. He wears what appears to be a kilt made out of vines and leaves. After a century of watching over the ravaged Avalon, Ogurien became sickly pale and bony, his hair grayed, his eyes became dark, except for his glowing pupils, and his clothes darkened, as though their organic material had started to rot.
