The Potter Lost In A Hurricane

Prolouge

When they were one, their home was broken into. A killing curse was shot at them both, reversing and hitting the spell castor, Voldemort. This curse left the boys with lighting shaped scars, one boy with his on his forehead and the other with a scar on his left palm. This same night two of their parents were killed. Their third parent, through complicated blessings, magic, and possession from afar, was alive and well on Mount Olympus. Also known as the 600th floor of the Empire State Building.
A half-giant came and brought them to their only living relatives, the Dursley of number 4 Private drive. There they lived for five years. Unexpectedly, on the 18th of August, a Hurricane swept over Private drive. This hurricane changed the lives of Harry James Potter and Perseus Sirius Potter forever.
The hurricane was magic, for how does a hurricane form high up north? And how does a hurricane make you forget your best friend? Nobody other than Percy himself could tell you what happened in that storm and when he was transported.
It somehow transported Percy Potter to a witch in America. This witch was told of Lilly and James, the mortal parents and that this child, was a child of the gods. Poseidon, god of the seas and storms, was this child's father. Sally Jackson however, was never aware of the second child, Percy never told her.
She married Gabe Ugliano, after changing Percy's last name to Jackson. In the years that followed, Percy was expelled from 6 schools and didn't tell anyone about his twin brother. He turned 12 and it was revealed who his father was (Poseidon) and he went on many quests. He had told his mother, Sally, about Harry on his actual birthday on the 31st of July. He went on to save the world several times in the course of 6 years. Not saying a word to anyone about Harry.
Harry Potter has remained in the abusive household of Privet drive. Everyone had forgotten entirely about his brother including Harry himself because if the mist and magic of the hurricane. At the age of 11, when he received a letter telling him he was a wizard, he was given the story of his parents, Lilly and James Potter. He went to Hogwarts school of witchcraft and wizardry, skipping the final year of his schooling to save the world of magic. He died at 17 years in order to kill Tom Riddle and end the war. He survived the attack just as he had on Hallows eve so many years before. With survival, memories lost to him in the hurricane came back. He now remembered Percy and everything about his brother. He did not breathe a word to anyone else fearing he had made up the whole situation.
Harry Potter and Percy Jackson had spent most of their lives without each other. Not aware of the other at all, and barely knew what the other was alive.
Monsters are gathering, evil forces are regaining strength and both brothers are going to be reunited and attempt to build a relationship.
