An attempt at writing horror without getting grimdark. Let's see how well it goes over. Diving into the depths of evil for the sake of a loved one, Fluttershy will face terror unlike any before. She'll fight against a creeping darkness born of two worlds, a sinister doppelganger who wields it, and her own sanity, stopping at nothing to save her human. Adapted for Fimfic, hope you enjoy.
