Okay, so these are a few snippets of the story, just as a teaser. When Twilight says: "If only we can save the Princesses and Discord." She wants them to be alright. Celestia, and Luna have lost most of their power during their stay in the dungeon, and Discord has been turned back to stone, but they all hurt as Maria65 defeated them with ease. She has the power to destroy the world, so it would be no surprise.
Anyways, I won't spoil anymore of the story, but it will take time to get to it as I have yet to finish the other stories I have started.
