Herodius is the leader of the Therans and the champion of Poseidon. He was selected by Poseidon for a wager with his fellow gods and sent Herodius after the Ambrosia of Asclepius or his island nation would suffer the plague. A seafaring warrior, Herodius set out to save his people.
Poseidon grew wary of Ares' champion, the Spartan Kratos, and told Herodius to defeat him or his entire island would die. Despite his best efforts and even wounding Kratos, he was killed and his men finished off by the other Spartans.
