Crossover with Dragon Age: Inquisition. Takes place after the main game.

Believing the world to be round, some of the wealthiest traders in Antiva sail directly east, hoping to land on the western shores of Orlais and Tevinter to open up new trade routes. However, they instead discover a new continent, one with its own Breach hanging overhead. Sailing to the new continent, the Inquisition hopes to put an end to the demons pouring out into the world.

A great big hole opened up in the sky over Equestria, and fearsome creatures began pouring out of it. Princess Celestia sent her best soldiers to fight them off, but the creatures keep pouring out. However, strange ships land in Equestria, and strange creatures calling themselves "The Inquisition" show up and claim to know how to close the hole in the sly.
