Resonance

After a near apocalyptic event ends most life in Equestria, Luna is sought out and is helped with the rebuilding of the once great Equestria.

My name is Silver La Vedette, and I have made a promise to the last known living alicorn, the legendary Princess Luna, that I will help rebuild Equestria, no matter what happens. What can I do to help being the earth pony that I am?
