Twilight had never questioned the nature of the Tree of Harmony. To her at least, it stood as a sentinel, a silent guardian watching over Equestria and keeping disharmony at bay.
She soon starts to have questions and misgivings when she inadvertently witnesses the horrifying fate of hers and the rest of her friend's twisted doppelgängers. Did something happen to the Tree of Harmony, or was it always this way?
Twilight aims to resolve this mystery once and for all. Little does she realize that this mystery goes far deeper—the truth far more terrifying than she can imagine.
Will she be able to solve this nightmarish mystery with her sanity intact, or will she surrender and be lost to madness?
After some deliberation I chose to put a Crossover tag as the whole story uses many assets from several stories in the Cthulhu Mythos (most of them written by authors other than Lovecraft).
