Dear Rainbow Dash,
I just wanted to tell you that Sombra won. He's going to become king. He's marrying Luna today. If you use your super speed to get here, I don't think you'll make it. I'm so sorry, Rainbow. But even though Sombra's taking over the world, I'm so proud of you. I never doubted that you would get your powers. I never COULD doubt you in a thousand years. You're incredible, Rainbow. Never forget me or your other friends. I know we'll never forget you.
Your Friend Forever,
Twilight
