CAMDEN, NORTH LONDON - a tangled junction of train lines, roads and the canal. Where minor celebrities hang out with minor criminals and tourists and moody teenagers mingle. In the heart of Camden you’ll 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 may be able to help. That’s if he’s not too busy avoiding his would-be apprentice, foiling the Dark, outwitting the Light and investigating a mysterious relic that has just turned by at the British Museum.
