Camp Half-Blood is the secret location where young demigods go to become heroes. They train their minds and bodies so that they can go on quests to stop their enemies from wreaking havoc in the mortal world. Camp Half-Blood is a Greek demigod training facility located on the north shore of Long Island. The camp is directed by the grumpy god, Dionysus, who the campers call 'Mr. D' and Chiron, a wise and kind Centaur who is the activities director. The camp has magical borders.
