Down in the town of Ponyville was a great celebration of the season, Hearth's Warming was on the horizon. Several years after Princess Twilight's coronation, many creatures Changlings, Yaks, even Dragons and Griffins, started to become part of this celebration. Not only does the Elements and Pillars make an appearance for the celebration, but the Successors, who are hailed as heroes in their respective community, commissioned them together, because they knew if anyone needed a break, it's them. But not far from the town of Ponyville was a mountain that once held a dragon. It's current resident had a plan to stop this holiday from coming into fruition.

Several weeks after defeating the Pony of Shadows, Starswirl recieved a message from one he hasn't heard from in a long time. He took Twilight, his successor, and traveled to the city of Purrsepolis to meet Starswirls old friend. The Purrsian Emperor.
