Henry Casey is a friend of Jack Conroy in White Fang 2: Myth of the White Wolf. He lives and bonds together with White Fang. He was the one seen by Lilly, child of Moses. His love interest is Lilly.

He gave Lilly a white cloth when he returned into the tribe. Lilly taught him how to use his bow. He was the one who planted the dynamite into the rocks that blocks the path of the animals. He also dreamed what Moses dreamed about, White Fang, Lily, but in that dream, also him.
