Once upon a time, a sensible young lady learned that she inherited magic. She could grant any wish she wanted, just once. But she didn't want to use magic to gain anything, so instead she decided to give her wish to her friend. She only realized too late that the magic was keyed to her, so even if her friend got her wish, it would be using her to make it happen... one way or another...
That's all the backstory this has. This randomly popped into my head a while ago, so I decided to doll it up and give it a post.
