When Twilight visits the Princess one day, she learns that Celestia is busy with some important guests. She goes into the Royal Library and gets interested in the tale of a young unicorn named Celeste. However, the book is a bit damaged, so she asks the Princess if she knows the story. Oddly, Celestia refuses.

So Twilight goes to the only other pony she knows who will have information. And it's not Pinkie Pie.

My first attempt at an adventure story. Sorry if it sucks.
