Hogwarts: From Selling White Peppers to Becoming a God

Murphy, whose worldview has been solidified by materialism, arrives in the idealistic magical world. Unable to adapt to the world, he decides to change it.
To reach the end of magic, he must concentrate resources, recruit talent, build an organization, manipulate human nature, and become the mastermind behind the scenes.
Murphy: "Give wizards technology, give Muggles magic. All for the greatest good!"
Auror: "That sounds nice, but you abused the three Unforgivable Curses, slept around doing all sorts of dirty work, violated the Secrets Act, infiltrated the Ministry of Magic, and controlled Gringotts. And you still say you're not a dark wizard?"
