Death Eaters
Lord Voldermort's legion of radical pure-blood supremacist practitioners of the Dark Arts
Where are they from?
The Death Eaters appearance in book four of the Harry Potter series, 2000's Goblet of Fire, essentially announced that the series was growing out of it's status as a children's series. Yea, they're evil dark wizards, but magical allegories for white supremacists are REALLY scary.
