Camp Half-Blood is a fictional summer camp for demigods, children of a mortal and a Greek god. It is located on Long Island, New York, and serves as a safe haven where these young heroes can train and learn about their divine heritage. The camp is protected by magical barriers to keep out monsters and other dangers. At Camp Half-Blood, campers are sorted into different cabins based on their divine parentage, such as Zeus, Poseidon, and Athena. They participate in various activities, including combat training, archery, and quests, all designed to prepare them for the challenges they may face in the world outside the camp.
