Hm...if I could make them sentient, my characters.
Er, most of them.
Probably not the psychotic pyromaniac mage or the shapeshifting contract killer, though. In fact, most of my medieval fantasy characters would probably be somewhat dangerous in the real world.
But the airship crew from the story I'm writing? Definitely.
Also, I'd make us a zeppelin and move all my stuff into it and we'd all live there happily ever after.
Oh, and I'd also conjure ectoplasm cages for random people and make them dance to get out for the helluvit.
