Eurytion

Eurytion is the son of Ares and Erytheia.

History
Eurytion started as a herdsman for Geryon, but accepted immortality when his father Ares offered it. He instantly regretted it, because he was bound to serve Geryon. Immortality meant thousands of years serving Geryon and killing anyone he wanted to kill.

When Hercules reached Triple G Ranch, no sooner had he landed than he was confronted by the two-headed dog, Orthrus. With one huge blow from his olive-wood club, Heracles killed the watchdog. Eurytion the herdsman came to assist Orthrus, but Heracles dealt with him the same way.

Because Eurytion was immortal, he reformed himself and was free until Geryon also reformed, as Geryon wasn't immortal, he was a monster.

The series
Eurytion finds Percy, Annabeth, Grover, and Tyson coming out of the Labyrinth. He takes them to Geryon, and is kind to Annabeth, and carrying a club.

It was Eurytion that suggested that Percy clean the stables in order to secure freedom for Nico, who was about to be sold to Kronosn by Geryon. Percy cleaned the stables, but Geryon laughed and said it wasn't a binding contract, and ordered Eurytion to kill them.

He refuses to kill the teenagers, and so Geryon proceeds to do it himself. Percy beats him, due to Hera's help, and tells Eurytion how to switch the rule of command at the ranch, by getting the animals on his side. Eurytion likes that idea, and lets them all go.

Personality
Eurytion is a cowboy herdsman, an exellent fighter, and a definate redneck. He has a soft spot for Annabeth, and refuses to hurt her. He doesn't approve of Geryon, but didn't do much to get rid of him, so he is possibly a little lazy as well.

Appearance
Eurytion is a huge guy with stark white hair, star cow-boy hat, and a braided white beard. He looks like Father Time, if Father Time went redneck and got totally jacked. Eurytion wears jeans, a Don't Mess with Texas T-shirt, and a denim jacket with the sleeves ripped off.
