Ornstein and Smough, two of the best bros in all of Lordran, appear in Equestria due to mysterious circumstances, and the ponies are none too happy about it. For years after their arrival, these two have committed every crime and atrocity in the book, and the only thing keeping them from destroying the world is their inability to focus on anything for more than a week at most. But now, in their ultimate bid for mindless destruction, the two sunbros prepare for their greatest crime against ponykind yet:

They're going to crash the royal wedding... royally!

Can Celestia put a stop to these two dangers to society before it's too late? Or will The Knight and The Executioner have their cake and eat it, too?
