said to be from his attempt to eat a stapler at age two. By the age of fifteen, he has earned the rank of praetor and leads the legion with his longtime partner, Reyna who eventually falls in love with him. Jason also coordinated the Roman camp's attack on the Titan force prior to the events of The Lost Hero: he led an assault against Mount Tamalpais/Othrys, a Titan stronghold near San Francisco, and defeated the Titan Krios in combat by himself. Piper McLean describes Jason as a very rule- and duty-oriented person, though Terminus describes him as a "rule-flouter”. Of all the characters in the series, Jason is the one who struggles the most with the differences between the Greek and Roman perspectives. When the Argo II is stuck in North Africa, he must choose one identity or the other; he decides to consider himself a Greek, despite his parentage, and is subsequently unable to command a legion of Roman ghosts. During The House of Hades, it is revealed that Jason has plans to return to Camp Jupiter to improve it with things he learned at Camp Half-Blood, such as giving the fauns (the Roman equivalent of a satyr) more rights and responsibilities. Later, during The Blood of Olympus, Jason decides to consider both the Greek and Roman traditions as part of his heritage. He becomes the Pontifex Maximus, a role which sees him travel between Camp Half-Blood and Camp Jupiter to build shrines for every god and goddess in the pantheon. He is killed during The Burning Maze by the Roman Emperor Caligula after sacrificing himself to save Piper, Apollo, and Meg. His death is avenged by Frank Zhang in The Tyrant's Tomb with Frank telling Caligula that it's for Jason. Jason is given a state funeral in New Rome overseen by Apollo. In The Tower of Nero, Nico senses that Jason has likely moved on to either Elysium or been reborn. Hazel Levesque Hazel Levesque is a fourteen-year-old demigod, a daughter of Pluto and Marie Levesque. She first appears in The Son of Neptune, at Camp Jupiter. It is later revealed that she has returned from the dead, assisted by her half-brother Nico. She grew up in the 1940s in New Orleans, where her mother had a gris-gris shop. When she was born, Pluto offered to grant her mother a wish, but her request for wealth backfired
