Send me a PM in letter format addressed to my good buddy Demon Dave, and he'll help you with all your problems!
I thought no one would, but someone did! Here is our first letter to Demon Dave. Dave, I'll let you take over now.
Dear Demon Dave,
Are you, in any way realted to Fable's Demon Doors?
Sincerely, Dr34m3r.
Hell, no! (And I knows my hells.) The Demon Doors are close buddies of mine, Dr34m3r, but related, no. We are not. But I can tell you which pop-culture demons I AM related to!
Hmm... let's see... Ifrit from Final Fantasy is my cousin, Etrigan the Demon is my grandpa, and Bill the Demon is my stupid little brother.
Hope that helps, whatever the fuck your name was. And by helps, I mean I hope it tracks you down and possesses your very soul with minions of Satan for all eternity until the Earth crumbles to dust.
Go away,
Demon Dave.
