by the Hephaestus cabin at Camp Half-Blood, and given wings by Leo Valdez years later. In The Lost Hero, he transports Jason, Piper, and Leo, before being destroyed by a crash-landing. Leo asks Hephaestus to take his head to Bunker Nine at Camp Half-Blood, where he later repairs him, to be the figurehead on the Argo II. Festus acts in this role throughout The Mark of Athena and The House of Hades. In The Blood of Olympus, Festus is secretly rebuilt by Leo and plays a vital role in the defeat of Gaea. Festus subsequently resurrects Leo with the Physician's Cure and helps him to rescue Calypso. In The Trials of Apollo, Festus acts as one of Apollo's allies. He is destroyed again in The Dark Prophecy, but is easily rebuilt by Leo who had redesigned Festus in case of such an eventuality. Piper McLean Piper McLean is a daughter of Aphrodite and the famous actor, Tristan McLean. She is fifteen in The Lost Hero. Unlike most children of Aphrodite, Piper is not particularly concerned with beauty or fashion. Piper is Cherokee on her father's side. She has tan skin, eyes that change color constantly, and choppy chocolate-colored hair which she cuts herself. Her demigod powers include "charmspeak" (essentially, magical persuasion) and the ability to speak French, as it is "the language of love". She is also occasionally able to see visions in her magic dagger Katoptris (Ancient Greek for "mirror"), which once belonged to Helen of Troy. The dagger lost that power after the battle against the giants in Athens. Piper's relationship with her father is mutually affectionate but strained, in part because of the small amount of attention he spares for her. When she was young, Piper used her persuasive skills to "borrow" (ask for in charmspeak) things to earn a little of his time. After he is kidnapped by the giant Enceladus in The Lost Hero and subsequently rescued by Piper, Jason, and Leo, Mr. McLean's relationship with his daughter begins to improve. Piper is also very close to Jason. Though she later learns it was all a trick of the Mist, she believed she was once his girlfriend while they attended the same school. She works hard to recreate this relationship in real life when she comes to Camp Half-Blood. She is also friends with all of the seven quest members in The Heroes of Olympus,
