Twilight remembers the night Celestia was murdered. It was the night Nightmare Moon returned, the night Canterlot burned. It was the eve of the Summer Sun Celebration. She remembers how the meteors tore through the banner, how the ponies scattered, how the buildings crumbled. She remembers the icy eyes set against fur as black as oblivion. The moon was full that night. It's been full every night since. Tomorrow night, the dragon migration will pass overhead, and Spike, her only friend in the world, will have to leave her. She's heard whispers of ponies making a last stand in Manehattan. She doesn't believe she can fight fate, but not even the Ouroboros knows what her fate is. He's very curious to see what she'll do next.
