List of characters in the Camp Half-Blood series
Hephaestus/Vulcan - The Gods' Blacksmith and God of Fire. He appears as a minor character in The Titan's Curse and as a major one in The Battle of the Labyrinth where he helps Percy numerous times. His children reside in Cabin 9. He is the father of Charles Beckendorf and Leo Valdez. He was thrown off of Mount Olympus when he was born because Hera thought he was hideous and wanted a "perfect" family, though Hera denies it. Hephaestus says that Hera likes telling the story that Zeus threw him off the cliff because "it makes her seem more likable." He defied Zeus' rule in The Lost Hero and spoke to his son. He also took the head of Festus to Bunker 9 for Leo.
