The Battle of the Labyrinth[]

Orthus had reformed along with Geryon. Although his official master is Geryon, he tends to listen more to Eurytion as he takes care of him, unlike Geryon. Similar to the ancient myths (Hercules), Percy Jackson, came to the ranch and killed Geryon, but unlike Hercules, he spared Orthus as he did not participate in defending his master because Eurytion had told him to stay back during the fight between Percy and Geryon. Percy Jackson, Annabeth Chase, Grover Underwood, Tyson and Nico di Angelo leave the ranch soon after this.
