I am not Twilight Sparkle.

I have her body, I have her memories, I have her power. I am not her, and I have done such terrible things. This is my story.

Twilight accidentally steps on a snail. This makes her sad. As the years go on, several other things happen.

I thought this was my first story rated 'everyone', but it isn't. It kind of is though? Anyway.

Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!

Twilight Sparkle's friends have lived long and happy lives. Now their time is coming to an end, but Rainbow Dash, at least, will not go gently. Twilight has the power to save her friend's life. Is it worth violating the natural order?

"The things that pull at your heart—the memorial in the prologue, the wedding in Chapter 1, the births and deaths and relationships to come—are not the point of the story: they are the stakes, and the story is at its heart about a decision that must be made."
