A training ground and safe haven for Greek demigods (half-bloods), located on Long Island, New York. Disguised from mortal eyes by the Mist, the camp is bordered by magical boundaries that protect its inhabitants from monsters. Demigods live in cabins dedicated to their godly parent, train in combat and survival, and undertake quests. Camp Half-Blood is directed by Chiron (the centaur) and Mr D (Dionysus, serving a punishment). The camp serves as the primary home base for the Percy Jackson and Heroes of Olympus series.
