Reminds me of a short story I once read in a Polish sci-fi and fantasy magazine, where a portal to fantasy world opened and Elves conquered Eastern Europe and I think Russia. At one point narrator tells us once Elves discovered humans made satelites, they made their own. Our of wood covered in magic runes, then coated with mithral. I don't recall how they got it in space but narrator tells us once it began orbiting the Earth and SENDING SIGNALS several members of NASA had to be instituionalized.
