Nar Shaddaa is one of the best known ecumenopolis planets in the galaxy; despite being a mere inhabitable moon with no discernible resources, its proximity to the Hutt throne world has elevated its presence to make it well-known from Coruscant to the Unknown Regions. The planet has been covered with sprawl since the early days of the Republic, when the Hutts moved onto the planet Varl, renamed it Nal Hutta, and evicted the native Evocii to the moon as slave labor. The Evocii, at the Hutts' behest, built docking bays and spaceports all over the moon, some extending into orbit, and over time the entire moon was completely urbanized. Massive cities grew, and the planet was soon named by the Hutts "Nar Shaddaa," or "The Vertical City." Because of the moon's proximity to the Hutt underworld, it acquired the more common moniker "The Smuggler's Moon." It has been said that just about anything can be illegally purchased on the moon. Many infamous criminals, pirates and smugglers throughout history made their start on Nar Shaddaa, and it's widely said that even the wisest Jedi fear to tread into the deepest bowels of the moon.

The moon has a population stretching somewhere between 72 to 95 billion; no organization is willing to conduct a census, and no one is brave enough to go into the lower levels where the feral degenerates and worst dregs of society dwell. It is said that the Evocii still live in the lowest levels, horribly mutated by the industrialization of the moon, but no one wants to find out for sure. As the Great Sith War and Mandalorian Wars ended, Nar Shaddaa was flooded with refugees who had lost everything and had nowhere else to turn.
One well-known sector of Nar Shaddaa is the Duros Sector. Roughly the size of a city, the area began to take its moniker after a small but brutal civil war on Duro about 10,000 years before the current time displaced many Duros from their homes. Having lost everything, many came to Nar Shaddaa, and most congregated together in large groups. Over the years, they made their corner of Nar Shaddaa their home, importing Durese architecture to the buildings there and expanding Durese businesses to the Vertical City. The Neimoidians, offshoots of the Duros species, poured their own resources into the Duros Sector, hoping to establish a positive relationship with the Nar Shaddaa Duros. As such, the Duros Sector still stands to this very day, and it is widely regarded as one of the most cosmopolitan and well-kept sectors on Nar Shaddaa. In recent years, the Duros Sector has seen a large influx of refugees again, as Duro was hit hard during the Mandalorian Wars.
Popular landmarks in the Duros Sector include:
- The Glitterstim casino, a classy establishment that offers sabacc, pazaak, trin sticks, legal sports betting, and all manner of gambling games from throughout the galaxy. The casino is well-guarded by a contingent of Trandoshans and droids who ensure that none of the violence of the planet creeps inside. The popular singer Merezel Keeg, one of the Duros Sector's favorite daughters, makes it a point to perform at the Glitterstim whenever she is on tour.
- The Zhug family estate. The Zhugs were one of the original families displaced in the creation of the Duros Sector, and they have maintained holdings here ever since. Successful in the blaster design business, they are one of the richest families in the Duros Sector, and all residents know not to cross a Zhug. As just about every Duros family on Nar Shaddaa has married into or out of the Zhug family at some point in the 10,000 years since the establishment of the Duros Sector, the Zhugs consider nearly all Duros on Nar Shaddaa family, blood or not. They have also gained a reputation for ruthlessness in their business dealings on Duro; many Duros say that they have too much Nar Shaddaa in them.
- The Slag Pit bar. When Torve Metal Concern, a front for the Hutt Faljozic kajidic, was shut down, their foundries in Hutt Space were left abandoned. An enterprising Neimoidian named Kund Ekorr took over one of them and decided to convert it into a gigantic bar. While the Glitterstim strongly discouraged violence, Ekorr realized there could be profit to be made by allowing weapons inside. The arms-allowed rule has led to an unusual peace inside the bar; knowing that everybody else in the building is well-armed is a strong deterrent against violence. The Slag Pit is known as the most popular bar in the Duros Sector for bounty hunters and pirates, and the large, cavernous factory structure allows for an enormous number of occupants. The back offices have been converted into private rooms for those seeking to avoid attention, and the slag pit namesake, a large melting pit in the middle of the bar, has been emptied and is used for raucous droid fights.
