So, in the ten years I've been writing pony fan-fiction, I have had a persistent dilemma: I love sci-fi, but the MLP universe is intrinsically a fantasy setting. Many noble stories have bridged that gap, including some of my personal favorites (Kkat's Fallout, Iceman's Friendship is Optimal, and Arad's Stardust, as a small sampling). But except for a few scraps in my short story collections, I've never tried to write a true Science Fiction story myself.
