Gray Goo in Fantasy: Apocalypse

Gray goo destroys a fantasy world, gray goo is going to win.

Far, far away, a planet orbits around a sun. Much like our earth, it hold people, animals, and plants. Unlike our earth, it has Magic. Also unlike our earth, it is about to have the greatest cataclysm ever known visit it.
