How do we know elves won't refine gunpowder weaponry first in their quest for ever greater ranges and precision? Maybe precisely engineered gyro stabilized rocket propelled 'arrows' is the path elves take, vs the humans big boom slow heavy artillery?
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.
