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?

Octavia has hit rock bottom. After the Gala and being forced to play that song, she was cast out by high society. Now she must gather the shreds of her pride, only to have to swallow them to work under the only pony that seems willing to hire her. Now it's time for her to make a name for herself all over again, and she's determined to make it no matter what, even if she has to start over from Scratch.

Just over two years after her banishment ended, Luna now rules over her night with Celestia's day. However, the night can become a very boring place, and when you have way too many hours of nothing to do, you tend to make... interesting choices in terms of activities.

Note: This takes place before season 3.

For the longest time, Epona has served as the loyal mount of Link, hero of Hyrule. But one day, she finds out that she's actually from a world inhabited by intelligent, colorful equines. And not only that: Her daughter is one of the six main heroes from that world. But that is only the beginning.

When the worlds of Equestria and Hyrule get into contact after a millennium, lots of hidden conspiracies are revealed. Evil fiends from a time long forgotten emerge and some ponies begin to understand their powers as sages. But the one important question will be: What will Epona choose? Her friends from Hyrule? Or her family from Equestria?
