So, yeah, perhaps you've already read about them when cruising another HP guide. Not so much? Well, then check out the details on these guys by going to Harry Potter and the Sorcerer's Stone. Or Harry Potter and the Prisoner of Azkaban. Or Harry Potter and the Goblet of Fire.

Or…yep, you guessed it, any of our guides on the Harry Potter series.
