For the past several weeks, Twilight and Starlight have been working on a secret project that they refuse to elaborate on with their friends. Only that it might change how they view the universe.

When the girls, and even the princesses, finally get to see what exactly the two have been working on, it's not what they expected. But what they hear on it will leave its mark on them.

Across the universe, a world is dying. And Twilight and her friends will hear its message.
