The investigators are in Nairobi, looking into the cult of the Bloody Tongue and the missing Carlyle Expedition. Before they can enlist the aid of locals, including a powerful mystic, they must prove themselves by stopping a potential agent of the Crawling Chaos, Mr. Corbitt and any other cultists in the city. Corbitt owns a mansion connected to evil, but what lurks in the basement will horrify even the most jaded of investigators. Can the team purge the evil hiding in the darkness?
