Meta Knight chuckled softly before replying. "Do you recall that disc I hit you with back in Equestria?" he asked. "The one that trapped you in limbo? That was something known is this world as a Trophy Stand. It can be used to turn anything into a Trophy, which are the building blocks of this hodgepodge world. As such, you were turned into a trophy, thus linking you and your entire world to this one. Whatever fate we suffer at the hands of Overlord V, Equus shall share that fate."
