Pandinus Imperator (You can call him Pan, he won't mind) is knocked back in time during the Canterlot Invasion, and accidentally kills King Sombra on arrival. Instead of being executed, the changeling is surprised to find himself being hailed as a hero, and is promptly put on the throne as the new monarch, the Crystal Emperor. However, Pan now faces a great many problems, among them Celestia and Luna, who seem certain that the changeling is secretly up to no good, as well as several political factions secretly plotting to undermine his reign. There's also the tiny problem of the constant snowstorm that threatens to cut the city off from the outside world permanently.
The Crystal Ponies need a hero now more than ever before. Why did they get a changeling instead?

Kuno and Warden are happily together now, but events are transpiring to force them from their happy life.

The reappearance of the Crystal Empire causes Kuno and Warden to give up their new-found home. And Kuno, ignoring the fact that they're two different species and completely incompatible, decides that she wants a baby.

Kuno, a young changeling, is left weak, bloodied, and bruised after the events of the Canterlot wedding. She is soon discovered by Warden, a Royal Guard. But for some reason, Warden shows her mercy. Instead of taking her into the custody of the Royal Guard, he becomes both her captor and her savior. But over time, Kuno will come to ask herself the hardest question she has ever pondered: Can a changeling feel love?
