List of Percy Jackson and the Olympians characters
Charles Beckendorf: A son of Hephaestus, known to be able to build almost anything. He is lead counselor for Cabin 9. He had a minor role in the first four books in the series, but has a larger role in The Last Olympian. He has a crush on Silena Beauregard, whom he starts dating from the short story The Bronze Dragon contained in The Demigod Files. Most members of Camp Half-Blood call him by his surname, Beckendorf. He sacrifices himself at the beginning of The Last Olympian to destroy the Princess Andromeda, a ship that was Kronos' headquarters, unaware that it was actually because of Silena (a spy on the camp) that he lost his life. Beckendorf was named after one of Riordan's former students.
