Backstorys:
In the year 2006 two children were born. The son of Perses, the titan god of destruction and peace, and the daughter of Tyche, the goddess of luck, good and bad. Let's start with the day that the boy was born.
The day the boy was born was the day when Perses' godly wife Asteria found out about his rendezvous with the mortal woman. Only hours after the child was born did Asteria kill the mother. But before she could kill the child Perses came and saved him. He took him away to a land called Paris and left him with the famous fashion designer Gabriel Agreste. He told gave him a ring and said that when his son turned twelve to give him the ring, and send him to Camp Half-Blood in New York. That's the birth story of Adrein Agreste son of Perses and Emily, bringer of peace and destruction.
There was a girl that was born that same day. She was the only daughter of the goddess Tyche. She was born of a man that owned a bakery. On the day of her birth her mother Tyche made a human replica of herself to care for the baby and father. She gave the replica earrings. She told her to give the child the earrings the day she turned twelve, and to send her to Camp Half-Blood in New York. That's the birth story of Marinette Dupain-Cheng, daughter of Tyche and Tom, bringer of luck.
