This story is a sequel to Starswirl and the Purple Terror

After the events in the past, Twilight can't help feeling dejected. She would never see Starswirl again. Or at least, that's what she thought right before he came knocking at her door. Meanwhile, in the past, a still somewhat immature Celestia is desperately trying to find a way to deal with the unfolding catastrophe. Luckily, her spymaster is always there, ready to lend a helping hoof.
