The Plumbers is a 5th edition Dungeons and Dragons one-shot adventure for a party of four to six first level characters that will take around 4 hours to complete.
A stone giant fortress deep underneath a mountain range has some plumbing problems as their water system has stopped working. They need help from little people to investigate and fix the problem.
Will the party be able to fix the plumbing problem or will the Giants be forced to abandon their treasured fortress?
While the adventure is set in the Forgotten Realms, it has been designed to be quickly adapted to any other campaign setting.
