All Down the Drain is a Fifth Edition adventure intended for three to five characters of 3rd to 5th level and optimized for four characters with an average party level (APL) of 4. A rise in thefts of valuable and arcane objects is unexplained in Aberdon. There is turmoil in the town’s underbelly, causing a solitary goblin motivated to seek unlikely allies and provide a lead regarding the thefts. This adventure occurs in the Freelands campaign setting but fits any existing campaign with only a few modifications and name changes.
Background
The town of Aberdon has grown steadily in the past few decades, and the local governors took on the challenging task of sanitation. They built a network of sewers to safeguard the townsfolk against disease and keep the streets clean. A goblin nest secretly took refuge in the sewers under the town a few years ago and figured out how to drain and isolate a cistern, creating a secret market in the last place anyone would look. Led by a charismatic goblin boss known as The Overseer, the market and goblins have thrived.
About a year ago, The Overseer started becoming uncharacteristically ambitious. Unbeknownst to everyone else, a hag named Idina assassinated them and secretly took their place. With the plan of finally binding a terrible creature she might summon, Idina used this position to have the underworld of Aberdon seek out magical prizes for her without having to put herself at risk. These thefts have gained the attention of the authorities above, threatening the safety of the market.
Adventure Summary
The characters are asked to investigate the thefts of several valuable and arcane items in the town. After some inquiries around town, the party is informed that a goblin has been captured who claims to have information that could be relevant. According to the goblin Vrizzt, her partner has been imprisoned in a secret market in the sewers at the order of its goblin boss. This same boss has been gathering magical items for some unknown purpose, using the town’s network of thieves.
