London's Century Exhibition has opened its gates and filled its pavilions with the marvels of modern technology. Something less marvellous is also at work inside them: a thief moving through the gaudy displays toward a specific and elusive prize. More alarming than the theft is what is descending from the Heavens, something aberrant and dangerous that the Exhibition's organizers did not account for. A Fallen London story about curiosity, time, and the consequences of making an enemy of both.
