This story is a sequel to A New Knight Rises
As we travel into more of Bruce Wayne's past, we learn that at one time in his life he always adored Christmas until that tragic night when his parents were gunned down by Joe Chill. All of the ponies of Ponyville were celebrating the wonderful holiday with their family and friends until, one of Batman's adversaries lands in Equestria to not only cause mayhem but laugh a little in the process. At the request of Princess Celestia, Twilight must use the portal spell to bring back the caped crusader to save Hearth's Warming Eve.
