You were apart of the hellfire club, but when you and your friends were in their respective homes, they magically transported into their actual campaign (don't ask me how I'm just the messenger-quote said by form tutor 24/7).

Your friends (Eddie, Mike, Dustin, Lucas, Gareth and Jeff) met like how you do meet in D&D and went into a nearby inn where they found their final friend, you. (P.S justice for the dude we don't know the name off)
