Infinity stones

So this is basically in the Marvel universe. You pick gender name and all the practical stuff but you're 14. Backstory: so basically when you where younger you lived in a place with war and when a bomb exploded near you something happened while everyone died you got out without a scratch and escaped you where send to an orphanage in New York City since you where like 4 when it happened you don't remember much. Story: well this is just a normal day you get ready go on the school bus and get to school your now sitting in class. what's gonna happen? You'll figure that out. Good luck
