After discovering Equestria, the Daedric Prince Boethiah decided to create portals linking Equestria to Tamriel solely to see both worlds clash against each other, but since her influence is far weaker in Equestria, she ended up only opening these portals all over the Nord homeland of Skyrim, where the Dragonborn resides.

The Thalmor and the dragons of Tamriel have entered Equestria, both with the intent of respectively exploiting and invading to further their own goals.

Now the Mane 6 must team up with the legendary Dragonborn to stop both the Thalmor and Dragons before they destroy Equestria. But will that be enough?
