Diagon Alley

An alley existed on the other side of a portal from New York City.

Shops
Several shops operated within the alley, including Flourish & Blotts, Quality Quidditch Supplies, Madam Malkin's, and Slug & Jiggers Apothecary. (WC: New Adventures Await!)

History
A woman once landed there after jumping through a portal and landed on a motorcycle which she rode down the street and out of Flourish & Blotts. She then narrowly missed a woman dressed in red and black, Marty McFly, and a man with pale white skin as they jumped out of the way. A man then gave Scooby-Doo a belly rub, as observed by the woman. E.T. then joined her and flew them into the sky, past Slug & Jiggers Apothecary and in front of the Moon above Hogwarts. (WC: New Adventures Await!)
