Invisibility.
Scientists out in the Conventional World have, at last, made the first steps to creating a material that makes whatever it covers invisible.
About time. I invented an invisibility suit a long time ago. As I told the sneering Stumpy, my assistant, I created a suit which made the wearer completely invisible. I even used it to visit the village a few times.
"Oh, really?" Stumpy curled the still-working part of his mouth. "Let's see it then."
"You can't see it. That's the point." Sometimes I despair.
"Where is it?"
"Damned if I know." That's the trouble with invisibility suits. Once you take them off, it's very hard to find them again. Stumpy says he's going to look for it. Sounds like a futile endeavour to me.
