2nd Reading: The Well by Mystery Pony Fiction

There's an old book that's falling apart. Twilight wants to copy it down to preserve it. But it needs to be as accurate and precise as possible, to preserve the state of the original. That shouldn't be too hard. After all, it's not like the text will change whenever she looks away.

Right?

My name is Twilight Sparkle, and I woke up today to find that everypony I have ever known has vanished. I'm alone in the world.

Help me.

Isn't Equestrian dentistry exquisitely simple? Cavity? Down a potion. Chipped tooth? A simple potion suffices. Lost tooth? Well, that may need three doses. Root canal? Clearly some kind of waterworks project. A vial or three, and all of one's issues have been solved!

...well, that was a nice dream. Time for Rarity to awaken unto nightmare...

Now with author Patreon and Ko-Fi pages.

Twilight wakes from sleep, but did the dream ever end?

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).
