The Heroes of OlympusEdit

The Lost HeroEdit

When Leo Valdez is claimed by Hephaestus, the Greek counterpart of Vulcan, a hammer appeared above his head as a sign that Hephaestus was claiming him as his son. Jason Grace was sure that it was Vulcan's symbol. This upset Leo as he said that he doesn't like Star Trek. Annabeth Chase corrected Jason, saying that Vulcan is the Roman name, as Leo's father is the Greek counterpart. Later on, Leo asked Will Solace, a son of Apollo, what was up with the name 'Vulcan', to which he replied that they go by the Greek names as those are the original ones.  Later in the book, Hephaestus visits Leo in an 'illegal dream' because Zeus had banned any communication with demigods. He tells Leo that he's been watching him for his entire life but couldn't figure out how to talk to him. He went on to say that he wasn't good with 'organic life forms'. Leo decided not to hold a grudge because he can relate to that. Hephaestus is cut short by Wheel of Fortune (the dream was somewhat like a TV broadcast gone static) and decided to give Leo one last but of advice. Everything can be reused and sometimes even the greatest machines fail. Leo doesn't know what that means until he wakes up to his bronze dragon Festus falling through the sky. It ends with crash landing in the yard of large mansion. Security lasers immediately popooo up when Leo tries to land in the hard and fry Festus. He then asks his dad to take the metal dragons head back to Bunker 9 for him and the wind picks up the head and carries it away.
