Balloon
He didn't even know how to fly the balloon. He'd been a passenger, not the pilot, that fateful day when the storm came in out of nowhere. The last thing he remembered was being told to duck down low in the basket - next thing he knew he was waking up to green, the pilot nowhere in sight.
Stuck in a strange land with no idea how to return home, he embraced it when the people started to praise him. They wanted him to lead them? Wanted to call him a Wizard? Fine by him! He needed something to do.
