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?

We Has A TvTropes.

While not truly a part of Bucking Nonsense's Changeling-Verse, the same rules regarding changeling abilities and society apply.

A millennium ago, give or take, Princesses Celestia and Luna were nearly defeated by the most powerful villain that they had ever faced, Grogar, the dreaded lord of Tambelon. Thanks only to the whims of random chance, the two princesses survived that encounter, but have been forced to live in fear of the time of his inevitable return. That time is now...

...But whatever revival was intended has gone a little... wrong. Behind the wheels of Grogar's body is the spirit of a slightly extremely eccentric human. Equestria would have been lucky to survive the real Grogar, but will the ponies fare any better with this loon ruling Tambelon?
