(Don’t mind the picture) it’s TPN so yah! But it is in season one and you were born there like any other character. Do have fun with your story!

You are a half-blood at least- your parental figure told you that after a hellhound attacked you, your currently trying to find a way out of a forest, still being chased by said hellhound trying to make it to a place called camp half-blood. If you can make it there you find that another half-blood appears a week after you. Which later turns out to be Percy Jackson, (this is my way of saying this starts in the first book, have fun and do whatever you want!)

Most people from Greek mythology are in this some gods, heroes, and all that. You can choose to be a demigod, mortal, or even a child of ghosts or spirits.
