List of characters in the Camp Half-Blood series
King Tantalus - Tantalus is a king from the Fields of Punishment who is the son of Zeus. He ended up there after killing his son Pelops, cutting him up, and serving him as food to the Gods. His punishment in the Fields of Punishment was to stand under a fruit tree in the middle of a lake where the branches and water would go out of reach from him. He becomes the activities director at Camp Half-Blood after Chiron is fired. He appears in The Sea of Monsters as a minor character. Even when hired as the activities director, he could not eat or drink as the food kept evading him. He is shown to hate Percy and his friends even more than he hates most half-bloods, yet shows favoritism to Clarisse such as naming her hero when the camp was attacked by Colchis Bulls or when she wins the chariot race. He throws a banquet in her honor. When the camp is attacked by a large flock of Stymphalian birds, Tantalus blames it on Percy, Annabeth, and Tyson's "bad chariot driving" despite that they were the ones who defeated the birds. When Tyson is brought to camp, Tantalus insults and makes fun of him even when Tyson is claimed by Poseidon. When at the end of the book, his curse is lifted by Dionysus just before he is sent back to the Underworld as he attempts to take some food along. Though none of the campers were sad to see him go.
