Gus

Gus is a demigod son of Hermes and a former camper at Camp Half-Blood.

The Last Olympian
It is said that he had stolen a pair of fuzzy dice from Chrysaor's Honda Civic in 1988 (Chrysaor, a flying boar, was the son of Medusa and Poseidon). These dice can still be found today residing in Big House Attic. It is unknown if Gus is still alive. If he is, he would be one of the oldest campers, being at least 36.
