Premise:
(This story is set in the world of "The Unexpected Love Life of Dusk Shine")

Soon after his ascension to Alicorn-hood, Dusk Shine and Spike decide to begin touring the local towns and cities for a while. Eventually their travels take him outside Equestria, with the Princesses and his friends in contact with him through letters.

However about a year later the letters stop coming, much to his confusion. They decide to cut their travels short and head back to Equestria to see what the problem is, however the home they return to is not the one they remember...

The Caribou have taken over and turned their homeland into one of sexual depravity, converting all the Equestrian males to their own twisted sense of morality, while all of the females have been enslaved.

Enraged and disgusted by the cruel treatment that the mares are forced to endure, he quickly makes his way to Canterlot. He and Spike try to get Shining Armor to see reason, only for him to demand that they either accept the "new rule" or be turned into mares in enslaved themselves. The duo just barely escapes capture and is forced to flee into to the mountains.

Now alone in the new Equestria where everyone is hunting them down, Dusk must find and reunite his friends if he hopes to defeat this new menace. Sadly it's easier said than done, what cruel fates have befallen the Element wielders in this horrible world?
