Swords, Dragons and Diet Coke

This short story was written for Matthew Leone's In which I give you the title of a song as your prompt contest. The word count is 1,219 and my song title was "Swords, Dragons, and Diet Coke" by The Devil Wears Prada. Be warned, I have never heard this song, so I have no idea what it's about. This however, is about the game Dungeons and Dragons and five guys who play it.
