"Oh, cheer up, it's not an everyday thing to see a magical kid among us." Dick flickers Jason's temple.

Yes, magical kid, that's what you are. Long story short, you're from a whole, another universe, or planet to give more information. At messing with wrong spells and supplies back in your home, you accidentally traveled here, where people call it Earth. You've heard from Earth before, a planet where humans live and humans, creatures who possess no power but can build things solely with the knowledge they gain. Thanks to your luck, you were dropped in a city named Gotham, and you met this bat thing, Bruce, or Bat|man. He temporarily took you in, until he finds a way back home for you.
