Mulmaster/Sewers

The sewers of Mulmaster were a rather ramshackle sanitation system of pipes and tunnels beneath the city-state.

Structure
The sewers primarily consisted of repurposed cellars, haphazardly connected together by a network of pipes and tunnels. These tunnels, which varied in height from, generally followed the contours of the city streets above.

The network was regularly in a flooded state, with water reaching up to knee height. Its tunnels were also unlit, requiring a torch to traverse, and thick with the stench of decay.

Functionality
With the city-state of Mulmaster having been built within a depression formed by an arc of overbearing peaks, most of the sewers tunnels were at an incline that became less steeper the closer they got to the harbor. Through this steep decline, refuse was gradually emptied into Mulmaster Bay.

Sewer Ecology
This sewer network had a reputation for monsters lairing within it, such as lacedons, though the creatures most commonly encountered were insects, rats, and giant rats. One could also find crustaceans in the areas closer to the harbor.

Groups of Interest
The sewers had a reputation for being frequented as a hideout by criminals. Because of this, they were regularly policed by the city-state's military.

History
By the late 15 century DR, many of the pipes and tunnels within this network were in a state of rusting and crumbling respectively.

In 1491 DR, a pair of mated flumphs by the names of Laal and Xol entered the sewers from the Underdark by means of a fissure, trailing the activity of a band of troglodytes. They two eventually stumbled upon the activities of the Cult of the Crushing Wave within a tomb that predated both Mulmaster and its sewers. When Xol moved in for a closer look he was discovered by the cultists and killed with two shots from a crossbow, his body left to fall into the sewers.

Xol's corpse was carried along by the sewers' streams until it came to clog up the mouth of a discharge pipe, its tentacles becoming snagged on a piece of metal. When the corpse was discovered by a group of street urchins it was mistaken for a monster, inciting panic throughout the city's waterfront.

Audra Maskyr, a sergeant in the City Watch, proceeded to hire three groups to investigate reports of monsters within the sewers and eliminate any threats they come across. One was a rather inexperienced band of adventurers that hailed from Sembia, who were press ganged early in the morning into doing. The second was a gang of Zhentarim mercenaries. And the third was another band of adventurers. The first group, after hearing the disembodied voice of Laal (a failed attempt at telepathic communication) pleading for help, they became convinced that the sewers were haunted. Later on they encountered the second group of adventurers sent into the sewers, who they informed them of their ghostly encounter.
