Nar Shaddaa, also known as the Smuggler's Moon, is the largest of five moons in orbit around the planet Nal Hutta. This ecumenopolis is one of the wealthiest locations in the galaxy, yet it is home to some of the poorest people, the lights and towers of its upper levels embodying pleasure and excess. Nar Shaddaa also serves as a symbol of corruption; run by the Hutt Cartel, the Smuggler's Moon supports a robust black market and is known for secretive dealings and illegal acts. Nar Shaddaa is the first neutral planet that the player will encounter, despite the Republic and Empire sectors being seperated, and it's level bracket is 20-24.
Nar Shaddaa is controlled by the Hutt Cartel, and has long been known for its lawlessness and corruption. Despite this, the moon's wealth and opulence has continued to draw individuals from across the known galaxy; those seeking the pleasures and experiences of the Smuggler's Moon willingly subject themselves to the whims and orchestrations of the various crime bosses vying for power within the moon's cityscape. Due to it's large population, it has also become an excellent place for fugitives to hide.
During the Great War Nar Shaddaa remained neutral, maximizing the moon's profits by dealing with both sides of the conflict. The Galactic Republic and Sith Empire grudgingly respected the Cartel's control of the city, but also recognized the potential gains that could be made in the moon's corrupt underbelly. Those found within these polluted and neglected lower levels respect no authority other than those with power, and it is here that numerous underworld conflicts, including that between the Hutt Cartel and the Exchange crime organization, play out.
