Chiron (Χείρωνας Κένταυρος in Ancient Greek) is the activities director at Camp Half-Blood. He is a centaur (a white stallion from the waist down) and the immortal trainer of demigods. He is a great teacher and mentor, and is extremely wise and clever. He is also an excellent fighter, capable of using a bow and arrow expertly. He can also use other weapons expertly, but his favorite weapon is the bow. He is capable of fighting Titans, as he took on Kronos himself. He is also capable of manipulating the Mist. Although he is said to be immortal, he is not because he had given his immortality to the Titan Prometheus. The gods granted his wish; that he could teach half-bloods until he was no longer needed (so he won’t die unless he stops training demigods). He is the son of Kronos. Chiron is also known as Mr. Brunner, a wheelchair-bound Latin teacher, because he went undercover to one of Percy Jackson’s schools (Yancy Academy) to teach Percy. In Greek Mythology, Chiron taught many of the famous heroes such as Achilles, Hercules, and others. He is like a second father to Annabeth Chase, who has lived at camp longer than anyone. It can be assumed that many campers see him in this way.
