What is a Devil King to do when he is bored as Hell? Take a vacation to the living realm, of course! And as chance will have it, it is a bored Devil King that comes one day to the quaint suburb of Privet Drive, few years before a certain baby is dropped on the Dursley's doorsteps. And a whole generation of children (both wizarding and muggle) is affected by the Devil's presence. The inspiration for this fic comes from reading "The Mind Can Make a Heaven of Hell" by TardisIsTheOnlyWayToTravel on fanfiction.net, in which "Sherlock is actually the Devil, but he decided to live as a mortal because ruling Hell was boring".
