Theseus

Theseus is the demigod child of Hestia, her only child. He attended camp like any other and had fun and friends with his cabinmates, cabin 11. But when he turned sixteen, his mother claimed him and all of his camp mates laughed at him and mocked him. He disappeared and was thought dead, but then he reappeared a hundred years later and assumed a new name, Theseus while at camp.
