"The Riverfront Rat Gang" is a ratfolk lair, also featuring wharflings and a doppelrat, designed for five 1st level characters. This adventure can be completed in one session. The old dockyards once served as the primary center of commerce in town. Years ago, political pressure from an influential merchant who wanted the docks to be loser to her business forced shipping concerns to move their docks upriver. The new facility accommodates larger ships, and the old docks fell into disuse. Talk of converting the property into a set of riverside shops died when a rat infestation proved to be an unsolvable problem. Thus, the old dockyards have been decaying for years. This situation suited a former thieves' guild member, a ratfolk rogue, named Matimer Creel. A botched robbery (for which Matimer blamed his accomplice) turned the guild against Matimer, who fled from certain death at the hands of the guild master. He hid out in the old dockyards, confident that not even guild members bothered to go there. From there he began to exact revenge against the guild by ruining its plans or stealing directly from it. He also befriended the rat population, thanks to a golden rat's tooth he acquired, and the vermin help with his schemes. A trio of rat-like wharflings and a doppelrat, washed up on the riverbank near the docks, have joined Matimer's retinue.
