Story Description:
Everypony enjoys myths and ponytales, even if they know such things aren’t real. Alicorns fighting against a spirit of chaos? An ancient princess trapped in a library under a tree, waiting to be found? Quite enchanting and fantastic tales yes, but nonetheless as fictional as Daring Do and other such stories. At least, that’s what Rarity used to think.She doesn’t anymore.
I found the fic on fimfiction rather easily by typing in enchanted library just now. You could try there to find it if you were using a different place before.
there’s a big difference between being new and being lazy.
also, some of these cover arts were designed within recent memory. i only just made and posted the Quantum Castaways one this afternoon. i’m not even sure the author knows yet.
let me guess, you’re new to derpibooru?
