The rock belonged to Jon and Karyn

The end of the note had the names 'Jon and Karyn' written on them. That was, curious enough? Leonard's eyes went wide. It couldn't be, could it? Nonetheless, he held the rock in his hand. Any wish he wanted was his to command, if its power was truly supreme. Maybe he could wish for the original owners to come and explain it to him? Or just make himself a billionaire and build a hyperdrive FTL engine to fly into the next galaxy. Wish aliens down? Curiosity beckoned as he held the stone, for want of a wish it gleamed in the flint of his eye.
