Epic Fantasy AU

You know how a lot of fandoms have fantasy AUs or something? MCSM is no different thanks to me (audience boos)! I haven't decided whether it's some crazy old-timey magical version of an actual plot from the game (remnants of some of the game's plots and/or scenes are scattered throughout this universe) or its own stand-alone plot. I'm leaning towards it being a stand-alone plot because why not?
