Karyn straightened, looked at the Stone in her hand and said out loud: "I wish I knew what precisely how the Remote changes people."
Karyn didn't see the flash of light. As the knowledge invaded her mind, she was hit by a sudden headache and shut her eyes hard.
The Stone clattered on the floor as she held her head.
"Blast it. Damn." She cursed, slowly opening her eyes.
A knowledge acquisition Wish is a coin toss. As the Wish itself is creating new information on the brain, which requires some physiological additions to the brain mass. Nothing major in the great scheme of things, but just as a sleepless night of studying high on caffeine and aderol can lead to headaches, so does magically acquired knowledge. And Karyn had just wished to know something not just very specific, but oddly complex.
Turns out that the Remote itself is a cursed item. Created through careless wishing, it exists to make things more interesting. Such definition is based on Jon's idea of what is mundane, boring. Common. On surface level, the Remote is a transformation device that turns people into a version of themselves who had been practicing, training and performing ballet from a young age. The cursed item also acted like the Stone in that it modified reality around the affected person. What makes it interesting is that it is an unexpected situation. Magic control Remote that turns people into ballerinas. Magic go brr! The world thinks it normal for this person to have always been like this because, in effect, the world has accomodated the new reality. A self-stitching rend in the tapestry of everything. The Remote shoots, the Wishing Stone glows.
But something like that would not remain interesting long, would it?
And that's where the curse starts.
