Steampunk adventure in the Victorian age

Marcus O'Riley (Riley) and his partner The Magician are freelance explorers who specialize in the retrieval of folklore objects and are forced by a secret government agency to retrieve a powerful object from one of the Grimm's Brother's fairy tales, the Infinity Pistol. In order to find the Pistol the two explorers must partner with a gorgeous Mexican artifact agent in order to find it before the warmongering Prussian's do.
