Publisher's blurb: The [second] in a new series of fast, approachable heists for Dungeon Masters who want to add a seedy underbelly to Saltmarsh, Waterdeep, or any city of their choice. Plunge your characters into an underworld of corruption, theft, death, and money, complete with its own rules, lingo, and protocols. A shadowy figure that calls themselves “Mr. Porter” reaches out to the characters about a job. They clearly have the skills needed for some skullduggery; or, at least Mr. Porter believes they’re desperate enough to try. Once you’re in, there’s no going back, but the reward is worth it…isn’t it? Nobody likes a gang war - at the very least, it's bad for business. Mr. Porter has heard that someone or someones are stirring up trouble between tribes of swamp folk around Saltmarsh, and that would be very bad for business. Get out into the boonies and see what's what - Mr. Porter wants to know if he has to short-sell his enterprises here. "Swampwater Rivals" is a short, one-shot adventure written for characters from levels 1 to 3. It is designed to be played in approximately 1-2 hours, and can be run with limited support from the Monster Manual or the Dungeon Master's Guide.
