Boredom and Its Implications

In an AU where LV doesn't exist, Harry Potter becomes the MoD after defeating Dumbledore in a duel. After that, he pursues a life of study. However, after many years, Harry gets bored. He, then, does a ritual to summon Death, and by chance, Death forces him to tell him his desire which was his yearning for being entertained. Death sends him to a world with Tom Riddle... in 1942.
