Annabeth Chase is the half-blood daughter of the goddess Athena and the mortal man Frederick Chase. She was born July 12, 1993. Being a daughter of Athena, who is a virgin, she was not physically born, but is a literal 'brain child'; she was born as a gift to the man her mother loved. When she was seven, she ran away from home. On her journey, she met Luke Castellan, Thalia Grace, and Grover Underwood. Together, they traveled to Camp Half-Blood, running from and fighting hordes of monsters. When they got to the borders of Camp half blood,Thalia made her final stand fighting monsters so that Luke, Grover and Annabeth could safely get into camp. Thalia's father, Zeus, changes her into a pine tree on top of a hill that comes to be known as Thalia's Pine Tree. Annabeth lived at Camp Half-Blood for five years prior to Percy Jackson's arrival.
