you don't know how it started, but one minute you and your family we're having a fantastic camping trip, then the next your family is dead, and you're the only survivor, and you don't want to go back to the human life, because you'll be taken straight to an orphanage, and you don't want that, so you live in the woods and adjusted your new life there. But you have no idea that all 100 of Zeus children got interested in you, they want a sibling, but obviously they want a full human sibling.
