Skullport/Heart

The Heart was one of the four wards of the subterranean city of Skullport. It was located in the easternmost portion of Skullport's main cavern. It was the highest-class area in Skullport and housed the bulk of Skullport's population.

Description
The Heart consisted of three levels: Upper Heart, Central Heart, and Lower Heart. The Heart was home to most of Skullport's permanent residents and held some businesses. The Heart had a less finished look compared to the rest of Skullport and was marked by stone columns and stalactites. Duergar, illithids, drow, and beholders preferred to live in the Heart for its resemblance to a natural cave, its shadowy recesses, and the darkness of its upper areas.

History
By 1492 DR, the Xanathar controlled Skullport and turned the city into a haven for his criminal organization. Under his rule, most local businesses were shut down, with the few remaining in business paying him protection money. Skullport's only remaining inn, Guts and Garters, and restaurant, the Worm's Gullet, were located in the Heart.

Lower Heart
Lower Heart was paved with cobblestones and large slabs of stone. Most of the buildings were in better shape than the rest of Skullport. Lower Heart had many unusual structures and landmarks, many predating the founding of Skullport and appearing dwarven or human in origin. There were few street names aside from Illithid Way, with most locals navigating by landmarks and businesses.

Notable locations included:
 * Beggar's Rest Pass: A deserted pass formerly occupied by beggars until it spontaneously liquefied into a muddy whirlpool during the Time of Troubles. Blood spilled in the vicinity of the pass caused zombies to rise from the pass and attempt to drag victims beneath the earth.
 * Dark Harvest Market: A food market catering to all Underdark tastes, selling average-quality Underdark and imported foods.
 * Illithid Way: The most prominent pathway in Lower Heart. Populated mainly by illithids, who were attracted to its warm, humid environment, shadowy recesses, and low-hanging column-like stalactites. Businesses rising from Lower Heart up to Central Heart catered to illithids and to a lesser extent beholders.
 * Rumblecleft Pass: A fissure opened along the south wall of Lower Heart by a series of earthquakes. It connected to a system of narrow natural tunnels leading to the River Sargauth and other locations in Underdark.
 * Steamfall Pass: A pass covered with a cloud of superheated ash and steam from Thaglar's Foundry. The floor was covered with thick mud and the pass was lined with odd rock formations from nearly two centuries of precipitation.
 * Taglath's Gap: a narrow stretch of cavern between Beggar's Rest and Steamfall pass haunted by the ghost of Taglath, a poet, explorer and romantic who was murdered at its threshold.
 * The Flagon and the Dragon: a small unassuming tavern once owned by Silas Broon; by 1492 DR, the proprietor was Cal'al Claddani. . Its acoustics made conversation below a shout difficult. It was popular with locals who wanted to converse without being overheard.

 * The Sanguine Hall: supplier of butchered meats, bones, and meat products to Skullport's businesses and ships, as well as secret butchering services.

Central Heart
Central Heart was primarily a residential area, housing some of the more influential and wealthy locals. The catwalks and rope bridges that cluttered the skyline were sturdier than elsewhere in Skullport, allowing most of the heaviest races free access.

Notable locations:

Upper Heart
Upper Heart was the darkest area of Skullport, with only occasional illumination from patches of glowing fungus. The ceiling of Skullport's cavern rose to its highest point in Upper Heart, with structures twining stalactites 300 feet above the cavern floor. The largest number of Skullport's darkness-loving races lived and did business in Upper Heart.

Notable locations:

 * The Worm's Gullet: a restaurant and casino made out of a hollowed-out petrified purple worm. It was formerly owned by Asheford Dockscourge and was one of the best restaurants in Skullport. By 1492 DR, it was managed by the duergar Gharz Stonedark and was the only restaurant in Skullport; the food and service declined under his management.
 * Tanor'Thal Refuge: a drow stronghold shaped like an obese spider clinging to the cavern ceiling. It was home to the emissaries of House Tanor'Thal and was headed by Kesra Tanor'Thal By 1492 DR the drow had abandoned it and it was empty save for a host of giant spiders.
