Sirius had nearly made a move to go sit down when Dorcas spoke up. He snapped his head sideways to look at her. It was shocking to hear people didn't know who "He" was, or what "He" planned. Not that Sirius really knew either, but he'd heard chatter. Even though he was the black sheep, Sirius was still dragged to pureblood attempt after pureblood attempt. He was pretty sure his mother still believed she could brainwash him into believing their rubbish.
Clearing his throat, Sirius shrugged. "Er, yeah. Well he... okay, have you guys heard of the Knights of Walpurgis? They're like, I donno, the Gentleman's club of purebloods. I don't know that they actually do anything, but I'm pretty sure my Uncle is one of them, and he's not what I'd call a nice guy. From what I've been able to pick up at parties, He is some alumni of Hogwarts that really fuckin' hates muggles. I think he is taking over the Knights of Walpurgis and getting them to do his bidding. Like, killing muggles, muggleborns, halfbloods, anyone who gets in his way. Ultimately, he wants a world run by him in which only purebloods live. Pretty fuckin' stupid, because inbreeding has already gone on for too many generations. Purebloods play dirty, I can tell you that much. And they don't really care who they have to blow out of the way."
