Victor Sassoon, a preeminent bon vivant, has found himself trading correspondence with Doctor Henry Armitage. They share a common goal and a common modus operandi. Victor fights to keep his empire safe, but he also fights for a Shanghai free from Mythos influence. Victor has gathered around him professors, detectives, muscles, guns, criminals and other problem solvers to mount a defense against a rising tide. Victor is your hook. The trail leads to... a strange gate opened by an ancient Daoist ritual, and an alien spirit called forth from the Polaris solar system. a Shanghai triad operated by someone claiming to be the deceased Empress Dowager Cixi. a scam at the horse track, a heartbroken triad gangster, and the Bloated Woman. a lost city of golden sands, a field of black lotus, and a place suspended in time and space. The Sassoon Files is 208 file pages long. Modular in design, each of the 4 scenarios may be played as a "one-off" session or as part of a larger campaign set in 1920's Shanghai. The scenarios are be tied together by common locations, characters, threats and themes.
