Julia is a six-year-old girl who helps Terminus, the Roman god of boundaries, at Camp Jupiter. She points for him and brings him things he can't reach, such as the weapon tray where Percy had to give up Riptide. She is a legacy of an unknown god.
When Percy, Hazel, and Frank are on their way to the Senate, who will decide what supplies they will be given for their Quest, they must cross the Pomerian Line into New Rome that Terminus guards, with the help of Julia. Terminus stops Percy and tells him that he cannot carry his weapon past the border and calls for Julia, who is standing behind him. She hides from his gaze as Terminus can't turn around to look at her (being a statue), but she eventually shows herself. She holds out a small tray for Percy to place his pen in.
Later after the battle with the Giant Army, she gives out party hats to people. When Percy arrives, she gives him a blue crown and gives Hazel a gold pirate hat and tells her that she wants to be like Percy when she grows up. It was then that Percy noticed that her missing front two teeth were just starting to come in. When Frank meets them, she gives him a hat shaped like a polar bear.
Julia is a playful trickster, who likes to hide from Terminus under his statue base when he needs her.
Julia has pigtails, wears dresses, and has two missing teeth. She is described as "impish looking." Julia also has two front teeth that are coming in.
