There were rules even on the Isle. Unspoken rules, but ones every one learned early.

Stay away from certain territories. Don’t go out at night. Never go anywhere alone. Don’t trust anyone. Don’t carry a weapon unless you’re willing to use it.

A place where every villain, every criminal, every scum of the earth was free to do whatever was no place for a kid. So you had to grow up early. If you didn’t you wouldn’t make it. As simple as that.
