With the launch of its prequel episode and final bit of DLC, Episode Ardyn, that's Final Fantasy 15 over as of today. You can show off as flamboyant bad guy Ardyn Lucis Caelum in events set before the main game. It was meant to be one of a series of one-shot, character-focused DLC episodes, but lamentably the rest were cancelled. 

Because this is Final Fantasy 15, you can't just play the DLC; you've got to watch some backstory, too. Luckily, the Episode Ardyn animated prologue isn't quite as long as the gorgeous and completely rubbish Kingsglaive. Take a gander below.
