Percy Jackson and the Olympians: Legends

Erebos is a gigantic humanoid creature with pale skin, dark eyes, jet-black braided hair, and no nose. His fingers are in the shape of sharp talons and has long tentacles instead of legs. He is also extremely muscular.

Erebos is a jealous and tyrannical ruler, proud of his domain as lord of all that ever lived. He is an effective warden and lord of the Underworld realm. However, he is not without compassion, but his compassion is limited to feeling on behalf of others what he feels, and his acceptance of his fate means that his lieges, the dead, must accept theirs. He envies the sunlit world of the living, but only in a daydream-like way. Erebos knows that all that lives will eventually join him, which affords him a kind of satisfaction and certainty. When others suffer, it brings Erebos peace, but not glee, because the alienation and banishment of others enable them to identify with his own. He doesn't take pleasure in the suffering of others, but he sees it as a necessity in the order of Theros.

Erebos is the primordial god of Darkness and Mist. According to myth, when the sun first shone on Heliod, the first shadow was cast. When Heliod saw it, he feared and banished it beyond the Rivers That Ring the World, the five rivers that form a boundary between Theros and its Underworld. That shadow was Erebos, the god of death. In time, Erebos accepted his role, knowing that although Heliod had banished him, he would always stand behind the sun god.
