Celestial Year 3678

The Equestirus 1, a floating pegasus paradise above the dying war-torn world of Equestria beneath them, is on the verge of collapse. The only hope for it's survival is the ones known as The Celestials, 6 beings of such extreme importance that even the most pure of governments would kill to have just one of them. But no one knows who they are. Sent on a journey by Princess Celestia, Twilight Sparkle must survive in the dying lands around Canterlot and find The Celestials before Equestirus crashes into Ponyville and destroys the world.
