Thalia Grace lieutenant of the Hunters of Artemis.

Thalia Grace is a daughter of Zeus and lieutenant of the Hunters of Artemis. She was once best friends with Annabeth Chase and Luke Castellan before Luke turned evil and gave his body to Kronos the immortal Titan Lord of Time in an attempt to destroy Olympus. Thalia renounced life at Camp Half Blood and joined the Hunters of Artemis so that she did not turn 16 and therefore was not affected by the Great Prophecy which would decide the fate of Olympus and Luke Castellan. Thalia's mom was a mentally challenged actress who attracted Zeus twice once in his Greek form which resulted in Thalia and once in his Roman form Jupiter resulting in her brother Jason Grace. Thalia and Jason did not see each other for years as Thalia believed her mom had abandoned Jason. Thalia is close friends with her cousin Percy Jackson son of Poseidon and she gets on her cousin with Nico Di Angelo son of Hades but she is closest to her best friend Annabeth Chase daughter of Athena.
