Hogwarts: My Entry Starts with Death Eaters

[Rich Second Generation] [Pure Blood] [Twelve O. W. L. Certificate Winners] [Proficient in the Imperius Curse]... With so many entry bonuses, guess who I became after traveling through time? It doesn't matter, I am the last member of the ancient wizard family. As long as I am not a Death Eater, I can live incognito. But why did I see Snape holding Veritaserum and the Minister of Magic coming in with dementors when I traveled through time? Help! Fudge is going to judge me with dementors! Don't come over here! I'm not Barty Crouch Jr.!
