Camden, North London. A tangled, mangled junction of train lines, roads and the canal. Where minor celebrities hang out with minor criminals, where tourists and moody teenagers mingle, and where you can get your ears pierced and your shoulder tattooed while eating sushi washed down with a can of super strength beer. In the heart of Camden, where rail meets road meets leyline, you might find the Arcana Emporium, run by one Alex Verus. He won't sell you a wand or mix you a potion, but if you know what you're looking for, he might just be able to help. That's if he's not too busy avoiding his apprentice, foiling the Dark, outwitting the Light, and investigating a highly toxic Relic that has just turned up at the British Museum.
