"Starlight! Twilight was destined to fail at repairing the Crystal Heart, resulting in the living snowstorm taking over the Crystal Empire and possibly all of Equestria, resulting in mass extinction of all life!
Also, thanks to you teaming up with Discord, Trixie and Thorax, you were not only able to rescue everypony from the second Changeling takeover, you metamorphisized the Changelings by your actions.

Everything in Equestria to this day would NEVER have been possible without the actions of one shining star - YOU. The fate of Equestria now lies in your hooves. Hats off to you."
