My name is Rainbow Dash and today I learned something new. I learned I'm actually a changeling. You'd think that would be something you would already know. I just learned it now when I saw my true self for the first time. How did I come to replace the real Rainbow Dash, and when? And why can't I remember it?

When something from Fluttershy's past comes back to haunt her, she ends up running away, and it's up to the others to figure out what happened. Will Rainbow open up about what she knows? Will Fluttershy solve her problems? Will Twilight succumb to the temptations of dark magic?

First "book" of The Saga of The Beast.

To those of you wondering who the "bad guys" or "good guys" are, there are none. When I write, I try to make sure everyone is doing the right thing (in their own eyes, at least), because there are no people who think of themselves as evil, except in hindsight. That's one of the things I try to reflect in my stories, so please, don't say "But I thought they were supposed to be evil", because they aren't. Not even the main antagonist is evil in this, and she even gets highlighted as a good person many times.
Just remember, evil is never a state of mind, but a difference of opinion.
