The kinda magic they don't teach at Hogwarts

"Let's go to that place in Knockturne Alley," you say. "It sounds...fascinating."

"Fascinating," Kat repeats with a giggle-snort. "That's the word you pick?"

"I mean, it would be a great contrast to the way magic is portrayed at school...."

"Shut up, Bruce. I know you're a perv." She whacks your arm playfully.

The two of you walk on until you're into the misty streets of Knockturne Alley. It's significantly darker and--like Kat--more gothic than Diagon Alley, and it was probably best described by The Leaky Cauldron's web site as looking like "the stuff of Oliver Twist in Hell." The two of you find the place quickly enough. It's called "The Wink and Tickle."

"Wasn't that the name of a brothel in Neverwinter Nights?" you ask, scratching your head.

"What's Neverwinter Nights?" asks a confused Kat.

"Oh, it's this computer game," you hastily explain. "Sorry, I'm muggle born, and I played a lot of video games as a kid. Actually I kinda miss them."

The two of you enter through the double doors and are immediately hit with the sound of dark, throbbing music, the kind with that magical sound to it, that magical sound that muggle music never managed to get. You're greeted by a thin woman wearing nothing but a witch's hat. She does a curtsey and says, "Welcome to the Wink and Tickle, the finest adult establishment in all of London! Would you like a tour?"
