Crossover between XCOM: Enemy Unknown and MLP. Twilight appears on Earth, shortly after the alien war. How will she cope with being taken prisoner? How will XCOM cope with the single most powerful psion they've ever encountered?
Social reject, blank flank, and failed candidate for Celestia's School for Gifted Unicorns. Twilight Sparkle holds little confidence for her future. But when even her own recluse world comes crashing down, will she choose to act?
Twilight Sparkle is the result of centuries of careful manipulations by the Princess of Equestria with the end goal of freeing the Mare in the Moon. Of course, it is difficult to affect ponies from space; control of dreams was most helpful.
