5 years have passed since the defeat of discord and Twilight has just finished her studies of magic, very few unicorns have ever accomplished this and at such a young age of 18 too. There has been something that twilight has always wanted to know about ever since her early days as Princess Celestia's protege, and that is "what is contained in the sacred library?" now the sacred library is considered somewhat of a myth in equestria, legend says that only a very rare few have been inside of this library and the ones that have, have never been seen again. Twilgiht feels as though now that she is ,politically, Princess Celestia's equal, that now she may be able to at least KNOW what the library contains, but when she is turned down yet again by the princess a mysterious creature appears offering her a way to not only know what the library contains but to actually gain entrance in the library itself. Will this mysterious creature deliver its promise, or does it have other intentions for Twilight?
