This story is a sequel to Starlight Glimmer Makes Many Mistakes
After her eventful vacation and all the good deeds she had done on it, Starlight was preparing to take over at the School of Friendship as Twilight got ready to ascend to the throne of Equestria. However, a few odd events suddenly began to take place around Ponyville. And according to Discord these events could be foretelling the doom of not just their world, but every world everywhere.
And it just so happens that a certain unicorn may or may not be totally to blame for all of it. Like usual, the world isn’t going to save itself, it’s up to Starlight, Spike and Discord to travel through reality and fix their (aka Starlight’s) mistakes.
Let’s hope there aren't any evil monsters lurking in the shadows.
