AUTHOR'S NOTE: THERE MAY BE SOME OOC BUT I AM NOT SURE YET… ENJOY! SORRY THAT THE FIRST CHAPTER IS REALLY SHORT!
Back in Ancient Greece, sons and daughters of gods were born with an unique sign. Think of it as a birthmark…but this meant so much more. Only two people had the same sign. Those people were meant to get married.
This sign resembled the child's godly parent, but also the symbol of another god. The second symbol was representing that a child of that other god will marry the child of the first god. If you were a child of Poseidon per say; you would have a trident. The second symbol could be… Athena's owl perhaps. That is what happened to Annabeth Chase and Percy Jackson.
The Fates chose the signs, but sometimes the Fates could be wrong.
Percy knew he had to be with a child of Athena. Annabeth knew she had to be with a child of Poseidon. They found each other, but it was too late. Percy Jackson had just met Thalia Grace. She didn't have a sign, which meant something that would break Percy's heart. She fell in love with him and the feeling was mutual, but she could never tell him about her non-existent sign.
Here is the story of when the perfect system of arranged demi-god marriage, was ruined.
