You had run away from home. You had lived with your two parents for as long as you could remember though some things always bothered you. First of all your mom/dad didn’t seem to be related to you at all while the other parent did. You also had two siblings that looked almost nothing like you. The mom/dad who was nothing like you, you had always suspected was a step parent but neither of your parents ever disclosed anything. The step-parent has always shown a visible distaste to you and favoritism towards your siblings. You were sick and tired of it. So you ran. While you were living on the streets you made a friend. This person explained that they were a satyr and that you are a demigod. It was hard to believe but there were already monsters everywhere. Why not? You and your friend/satyr were currently in the Manhattan area when a monster attacked you. It looked like a gryphon, a monster you had read about. That's when a teenager walking down the street rushed into battle with you. He took out a pen/sword and rushed in without thinking. He gained a hit on the gryphon then took your hand and began to run.
