It was well known among those who knew of magic that most magic was reversible. It was also well known that there were exceptions. Sixteen of them. In all the world, perhaps all the universe, there were only sixteen unbreakable enchantments.
A twenty five year old masic'n sorcerer was closing in on one of them. It was a medallion that could change anyone into a young girl, but he assured himself that that wasn't why he was after it. Sure, he had wanted to be female since he was little, but he told himself he was after the medallion for religious reasons. Even though he had no religion.
It was simple really, he wanted to break the unbreakable enchantment.
If even one of the so called unbreakable enchantments was broken, even for an instant, it would prove that there was no such thing as unbreakable enchantments, and all sixteen would collapse in on themselves. There were those who would do anything to stop him, and even more who believed such a thing was impossible. It was widely accepted that, while a few of the sixteen were frivolous, in large part they maintained order. The sorcerer had no problem with order, as far as it went, but did have a problem with absurdity.
It was absurd, for example, that a masic'n couldn't change himself, when it was find for him to use his powers to change anything and anyone else. If it weren't for that he'd have become a woman long ago, but he always reminded himself that wasn't why he was doing this. It was also absurd that magic couldn't be revealed to the world just because in the middle ages someone thought it would be better that way. Magic could cure cancer. It would be trivially easy to end cancer once and for all, but it would require a public network of magical healers, so it couldn't happen. Where was the sense in that?
Some called it order, but it seemed to him a form of insanity. The whole world was slave to sixteen enchantments. So he had tracked down what he considered the weakest. It effected only one person at at time and having no altruistic purpose it had no protectors.
When the sorcerer arrived he found not the medallion, but instead the medallion's latest victim. After listening to the explanation that left the little girl crying on the floor. He corrected a some points, "Two things. First, the medallion didn't destroy itself, it simply transported itself elsewhere looking for another victim. Second, I believe this can be reversed."
After an explanation of what he wanted to do, and the risks involved, the girl agreed and he got started. It was difficult, but masic'n training started at the age of five, and for the past ten years he had devoted himself to preparing for this moment. Soon the little girl was a 15 year old boy. It's "unbreakability" broken, the medallion became a simple magical object, which the sorcerer called to him and reprogrammed. From now on it would seek out those who wanted to be changed, and help them.
One enchantment broken the sorcerer immediately tested another, he turned himself into a woman. Once impossible due to another "unbreakable" curse, he now encountered no difficulties. He, or rather she, decided from now on she would be called Mandy.
Mandy took the boy, Paul, home where he discovered his room had changed back, and his mother remembered him for who he was, not a little girl named Paula. Upon verifying that his memories would remain intact Mandy said goodbye. When she stepped outside she saw just how successful she had been.
Above the town a dragon was flying. Some people were cowering in fear, but the needn't have been. It was simply happy to fly for the first time since a radar had started to monitor the area years before. It, and other magical creatures, was no longer compelled to keep itself hidden.
Mandy only stopped watching the dragon when a unicorn next to her made itself known. Not like the fakes seen in movies, it had not just the spiral horn, but also the tell tale cloven hooves and goatlike beard. This was a real unicorn. Even sorcerers thought they were extinct or merely legend. Now Mandy was face to face with one. What was more, it seemed interested in her. When it offered to let her ride it, she didn't hesitate.
The unicorn carried Mandy off into a brave new world.
