She walked through the border with ease so she figured that she was a demi god in fact a very powerful one stronger than Apollo himself. She goes on a quest to save Leo her best friend and crush of two years. She leaves camp with this prophecy:

Four shall go to land of fire ,
To save the child of the gods.
Face an enemy only he defeats ,
defeat the enemy to save the weak.
Beware of the evil you call a friend,
fight until jealousy's end.
In the end fire and fire shall love
Beware of the dove.
