List of characters in the Camp Half-Blood series
Daedalus - Inventor of the Labyrinth, son of Athena, and father of Icarus. Daedalus killed his nephew Perdix and took his notes, which he then used to cast his animus (soul) into automatons after Athena branded him with the murderer's brand. He originally owned a hellhound named Mrs. O'Leary and fights the Titan army toward the end of the fourth book. He later decides that it is time to go to the Underworld and leaves Annabeth his laptop which is filled with his notes and ideas. Nico unleashes Daedalus' spirit which destroys the labyrinth. When in the Underworld, King Minos tried to convince the other judges to punish him and fails. Daedalus' spirit now works as the Underworld's architect while being able to visit Icarus and Perdix on weekends.
