James Potter & Sirius Black & Xavin
I was born just before a war broke out between my people and another powerful people, the kind of war that can last for generations. My parents died during it, and their generation carved hatred right down to their bones. Same on the other side. I know how to kill, but I tried for peace.
It is challenging to start at the top. A worthy goal, though I understand your parents' doubt. In my experience, young children can get into cookies anywhere.
