The Clockwork Circus is visiting the steaming city of Duesfer, bringing many strange and wonderous things, and a spectacular show full of steam, fire and daring acts. But not is all as it seems, and the performers are hiding a secret, one that would ruin them if it came out. So when they receive a strange letter, they're left with only one choice: disappear into the night, never to perform again, or do exactly as they're told.
