SilvusK
After the war, Harry Potter began living a life shut off from society, constantly dodging interviews, investigating the Potter and Black libraries, until he caught the attention of an Unspeakable by the name Silvus.
Silvus believes that Harry has enough raw magic to use his latest invention, a time machine that can send a person on a specific date in time if the person has enough raw power and will, like an overpowered apparation.
Harry agrees, and, after half a year, packed with communication devices and supplies necessary, he uses the machine to go back before his birth. However the machine mistook his year, and ended up landing in front of a road, his device reading, July 31, 1930.
Fuck.
