After the door is marked and closed and double-checked, Magnus picks one at random. The door opens into the center of a cross-shaped junction of big, sweeping halls with dim windows and a single, flickering light behind an exit sign to the right. The air is stale and mouldered, like the defunct air conditioner molded as it cranked out its last gasps of air. The anchors of this derelict mall are McAlpin's and Marshall Fields, and they're as dark as the rest of it. Even at this distance, it's clear the food court to the left still smells of old grease. There's a shuttered Waldenbooks that still has one display out with three dusty coffee-table books yellowing on the stand, and a shuttered Limited Too that's full of just bare wires. The Piercing Pagoda in the middle has a broken display case, and the Auntie Anne's has a bucket with a mop sitting on the counter.
