From publisher blurb: It moves in the shadows... Maude Lucrentino has a problem. She believes that the people she employs to work in her iron mine might be smuggling rocks pearls - glittering gems like a cross between diamonds and pearls - out of the mine and selling them to disreputable jewelers. To investigate the suspected smugglers, the Fated will have to go undercover at the Noth Mine, posing as miners, camp guards, and cooks. As they begin to uncover the identities of the smugglers, however, they will gradually realize that something terrible stalks the shadows of the isolated mining camp... Heart of Darkness is a fun One Shot adventure for the Through the Breach roleplaying game. It requires the Fated Almanac or the Core Rules to play.
