Waterdeep/Sewers

The sewers of Waterdeep were a sanitation system of tunnels beneath the city that connected to most locations throughout the city, including its dungeons.

Structure
The depth of these sewers varied around Waterdeep, due to Mount Waterdeep and the plateau the northern portion of the city was built upon. The Field Ward, the harbor islands, and the heart of Mount Waterdeep were the only areas in the city that the sewers did not run beneath. With some areas having around two to three sub-levels.

Partially due to city’s ever changing layout, the tunnels of this sewer system did not match up with the routes of the city's streets by the 14 century DR.

Functionality
Refuse, as well as air, were brought down into the sewers by numerous feeder pipes scattered throughout. These pipes measured less than in diameter. Thanks to the pipes, air supply was good in the sewers and those who traveled in them had little chance of suffocating.

The sewer network operated on a system of tidal flushing, meaning that its waters were flushed out by the ocean tides that came into Deepwater Harbor. The sewer's tunnels emptied into the harbor at places that were covered by extremely large and strong gratings. These places were purposely difficult to access, as the sewer network's designers sought to hamper the movements of less desirable visitors from the sea and to prevent the sewers from being used by criminals as an underground highway.

The areas in which the sewer network was constructed at, as well as the varied sizes within, were designed to optimally account for the ocean tides. Their layout was also dictated by where springs rose and flowed down to the sea. And finally, due to the city's great size, Ahghairon and other mages bound spells into the city's wards and bound some elementals. These both assisted the flows of water in carrying away sewage, thereby ensuring that the city's harbor did not become a cesspool.

Some areas of the sewers featured doors that would close upon water entering from a certain passages, ensuring flooding did not occur. Others had pressure plates that would close doors once water stopped flowing over them, preventing backwash.

Construction
The ceilings, floors, and walls all throughout the sewer system were made of masonry, often times with paving bricks. There was little to no lighting within the sewers and a terrible stench pervaded the entire network.

Gratings in the sewers were all made of iron and quite thick. Some were permanently set into the stone walls, while others could swing open on pivots. By the 14 century DR many were suffering from rust.

Passages
The passages of this sewer network had no names, thus directions tended to be given in terms of entry points and paces. Those who worked in the sewers were known to navigate passages by laying down boards as temporary bridges or by vaulting across ledges with catchpoles. The latter of which were carried in order to reach below the water and clear debris from gratings.

Passages were denoted as being either one of two types based on their size, primary and secondary. Primary passages were easily navigable. They measured across and had parallel,  wide, walkway ledges that lacked rails. Secondary passages were smaller, requiring human-sized creatures to crawl or swim their way through. They measured and had on one of their sides, usually the more easterly or southerly side, a single  wide ledge.

Besides these two types there were many older, smaller passages that had over time been put out of service and walled up by the 14 century DR.

Portals
Some areas of the sewers featured stone portals, a network built by an old dwarven kingdom to quickly move about. These required special enchanted stone items to activate, which took a variety of forms. These included daggers, gemstones, holy symbols, medallions, necklaces, orbs, rings, and scepters.

Some areas featured teleportation pads that were constructed by the sewer network's designers. These would teleport people to the surface, acting as an emergency exit for sewer workers in the case of flooding or other hazards. When broken, they would only teleport people elsewhere within the sewers.

Interior Connections
The sewer network notably featured connections to the dungeon complex under Castle Waterdeep, the Dungeon of the Crypt, and in several places Undermountain. Many such links were kept operable and secret by the many guilds and shady organizations that operated in the city.

Connections with Undermountain in particular featured heavily in the city's tavern lore.


 * Dungeon Level: This first level of Undermountain had a tight winding crawl space, the Grim Passage, that ended at a secret door high above the headless relic known as Grim Statue. This was entered by means of a hidden door in the sewer passage beneath Slide Alley. This sewer passage paralleled the docks north of Sail Street, branched near Mirt's Mansion, and linked up to a junction room (SF48). The Grim Passage itself wound and twisted through the rat-infested remnants of old, filled-in and forgotten cellars and disused privy chutes, until curving into a dead end where the hidden door above the statue laid. The drop down to the Grim Statue was roughly.
 * Fireplace Level: This complex of rooms within the Dungeon of the Crypt was connected to the midden of the Grinning Lion and a junction room in the sewers beneath it (SF31) by means of a secret staircase.
 * Lost Level: This sixth level of Undermountain was connected to the sewers by means of a portal that was visible only on the night of a full moon in the month of Flamerule.

Sewer Ecology
There were a great deal of creatures that inhabited this sewer network, far more than could logically be expected to find enough food to survive. Many of these creatures entered the sewers by means of the Dungeon of the Crypt and Undermountain. There were also a wide variety of fungi and oozes that lived in the sewers, with there being a small chance of an ooze crawling its way up the privy pipes of the sewers.

Adventurers, wizards-for-hire, and mage guilds were regularly hired to go into the sewers to sweep and clear monsters out of areas. Such groups sometimes hired Cellarers to guide them through the sewers at the cost of 20 gold pieces a day, but such guides never carried weapons and would stick to only traveling the primary passages.

Surface Shafts & Junction Rooms
Some areas connected between primary passages, known as junction rooms, were square in shape. They measured by, were  tall, and had a sitting ledge near their ceiling.

Entrances into the sewer network were known as surface shafts. They measured in diameter, were typically spherical in shape, and had iron rungs set in the walls for use as ladders. They were capped by covers made either wholly of metal or of metal-banded wood. These covers were known as "manholes" or "person access covers."

 * Safehaven: An inn in the Southern Ward, whose cellar contained a hidden ladder leading down to the sewers. This ladder was hidden behind a tall door, which opened upon turning upward the spigot on the last wine casket.

Groups of Interest

 * Cellarers' & Plumbers' Guild: Most members of this guild learned the general layout of the sewers after two to five years. This is because their primary concerns were keeping the sewers of the city functional and safe, with guild members being engaged in constant small repair jobs in the sewers, such as on plumbing in old buildings. They also possessed maps of the sewers, but they never sold them.
 * City Guard: In the late-14 century DR, it became the duty of the City Guard to police the sewers.
 * City Watch: Up until the late-14 century DR, it was the duty of the City Watch to police the sewers. After this authority switched over to the City Guard, watchmen rarely ever entered the sewers. Only doing so if pursuing a suspect or when they discovered sewer tunnels that connected with cellars.
 * Confluence: The lower status members of this secret society used secret passages within the sewers to enter Tespergates, their organization's base of operations, by means of the villa's cellars.
 * Cult of the Rat: A beast cult that worshiped Sneel, the lesser deity of rats, lived and operated in secrecy in the sewers throughout the 14 and 15 centuries. Many of its members were individuals who allowed themselves to be afflicted with the wererat form of lycanthropy. They often had offerings to Sneel in their warrens, meant to try and earn his favor.
 * Dungsweepers' Guild: This guild normally did not work on the sewer system, but for security reasons the city reserved the right to contact the guildmaster and hire members to help in such work.
 * Guild of Watermen: Members of this guild knew various spots where the sewer system emptied into the harbor.
 * Merfolk: Living within Deepwater Harbor, these people regularly patrolled the areas where the sewers emptied. They would use pole mounted catch-nets to scoop up and gather any debris they found into large tow-globes, which they then used to transport the debris far out to sea.
 * Plague Rats: This elite organization of thieves and assassins operated mainly under the cover of darkness in this sewer network and the Dock Ward.
 * Savants of the Dark Tide: This aboleth-led criminal organization had its base of operations within this sewer network and mainly operated within it.
 * Unseen: This secret society operated out of both the sewers and Rat Hills for decades, but following the Rat Hills Conflagration they began having their main meetings within secret rooms in the sewers. Their leader, Hlaavin, also kept many safe houses within the sewers.
 * Xanathar's Thieves' Guild: This guild had safehouses scattered throughout the sewers, hidden by secret doors. Tunnels were often marked with the symbol of the guild in yellow chalk, helping to guide members to the safehouses. Every few days these were erased, either by members of the guild or by the Dungsweepers' Guild. The guild also utilized some of the stone dwarven portals that were scattered around the sewers.

History
These sewers were built over the course of many generations, dating as far back as 1162 DR. As far back as this date, there existed three levels to the sewer system.

During the days of Ahghairon, a number of Underdark creatures tried to invade the sewers and Waterdeep proper by means of a portal within Undermountain, which he put an end to by means of the gatewarp spell.

At some point a group of dwarves established a kingdom beneath the sewers, which eventually fell into ruin and became a mere legend on the surface. Their ruins were later discovered by the archeaologist Wently Kelso.

In 1208 DR, in the month of Kythorn, some unauthorized construction was discovered on the second level of the sewers.

After securing what would be renamed the Citadel of the Bloody Handy in 1262 DR, the Shadow Thieves constructed two links to the sewers of Waterdeep.

In 1280 DR, in the month of Mirtul, some trapped sewer gas was cleared from an area on the third sewer level. A year later, on the month of Kythorn, a cistern area was added to the second level of the sewers. And in 1292 DR, on the month of Tarsakh, flood control gates on the second level were repaired and additional ones were installed.

In 1298 DR, the Shadow Thieves were driven out of the city and the Lords of Waterdeep had the citadel's two passages to the sewers garrisoned by the City Guard. From then on they were occasionally employed by high-ranking occupants of Castle Waterdeep when a discreet exit was desired.

Some time in the late 1350's DR, on Mirtul 15, twelve tanystropheus eggs ordered by Phalantar's Philtres & Components hatched and escaped into the sewers via a garbage chute. That night a crew of Cellarers were attacked by the young dinosaurs while laying a large, heavy length of pipe. One member was killed, while two others were badly mauled. Frustrated by this, the guild offered a reward of 200 gold pieces for their capture (dead or alive), while Phalantar Orivan himself offered 500 gp for live specimens and 100 gp for dead ones. By the end of Uktar, it was assumed that any tanystropheuses not recovered were dead from the winter weather.

Around this decade, false and terribly inaccurate maps of the sewers were being sold by people trying to pass themselves off as Cellarers.

In 1355 DR, in the months of Ches and Tarsakh, flood control blocks were proposed for some areas of the upper sewer level.

In 1358 DR, during the Time of Troubles, the mortal avatar of Myrkul opened a portal between Hades and the Prime Material plane. Hoards of undead came rushing out through the sewers and up into the Dock Ward. The guardsman Ylarell tracked these undead and in the process was slain by Myrkul. Five Cellarers also became lost in the sewers during this time, having been transformed into cursts that continued to patrol the sewers for decades.

In the wake of Myrkul's destruction a deathshrieker was created in the sewers beneath what later became known as Cynosure. It would stalk the sewers for over a decade.

Also during this year, an adventuring band under orders of the Lords of Waterdeep traveled into the sewers to put an end to the plans of Xanathar. Before embarking into their depths the adventuring band was gifted by Khelben Arunsun with a partial map of the sewers and a copy of Wently Kelso's The World Beneath Waterdeep, which included several notes on the hazards and creatures they could expect to encounter. Secretly aided by another beholder, the adventurers managed to slay the crime lord and present his eye stalk to the Lords of Waterdeep, while the other beholder assumed the identity of Xanathar and took over his criminal organization.

In Eleint, 1367 DR, new creatures began to be encountered in the sewers by members of the Plumbers' Guild, such as sewerms. Some of these new creatures originated from the Rat Hills, such as gulguthydrae, having fled into the sewers following the Rat Hills Conflagration.

In 1369 DR, during the event known as Halaster's Higharvestide, a number of creatures crawled out from the sewers and terrorized the people of Waterdeep. Following this event, the guard station located near the northern entrance to the Citadel of the Bloody Hand became primarily concerned with guarding against the living spells that still remained after Halaster's Higharvestide.

That same year the city faced an attack by the forces of Iakhovas. In the wake of that repelled invasion a number of sea creatures escaped into the sewer system, with some of them, like the malenti Laaqueel, having been led into the sewers through a surface shaft at Coin Alley by Iakhovas himself.

Among the dozens of aboleths that fought in the army of Iakhovas there was one trio, hailing from the Swordsea Depths, who had joined in this assault for the sole purpose of using the chaos to sneak their way into the city's sewer system. Within the sewers the would-be Savants of the Dark Tide established a lair, then over time gradually enslaved members of the Cellarers’ & Plumbers’ Guild and transformed rogues into skum servitors.

Around 1372 DR, the doomsphere Xliiqil began stalking the sewers, trying to learn what happened to the Company of Crazed Venturers who had slayed it decades prior. Also around this time, eyeballs and lurking stranglers roamed the sewers on behalf of Xanathar.

In, shortly after Mistshore was largely destroyed in a massive fire, Xanathar had some areas of the sewer network diverted in order to give his organization more space, which resulted in a large daily influx of sewage into Deepwater Harbor. Merfolk who lived nearby made attempts to clean the area, but were slaughtered by an undead eye of the deep under Xanathar's command. Eventually, Laeral Silverhand intervened &mdash; the meddlings of Xanathar were undone, the eye of the deep was slain, and harbor waters were revitalized.

In 1492 DR, Jeryth Phaulkon sent awakened rats into the sewers to search for Xanathar's hidden lair, eventually discovering a secret spiral stairwell in the sewers beneath the Castle Ward.

Rumors & Legends

 * Some rumors claimed that the cellars of some of the City Watch's guardposts contained secret entrances to the sewers.
 * The Cliffwatch Inn's cellars were rumored to have secret passages to the sewers.
 * There were persistent rumors that Uluryk Malogh made an extensive map of the city's cellars and sewers, detailing all their various barriers, locks, and traps.
 * Around the mid-14 century DR, there were rumors circulating that Xanathar's Thieves' Guild had trained guard rats roaming the sewers and that slavers dwelling within the uppermost rooms of Undermountain creeped out into the sewers at night to kidnap unsuspecting Waterdhavians.
