Nar Shadaa was Nal Hutta's largest moon.Ancient refueling spires and loading docks reached out from the native soil and some built in the upper atmosphere. In between these ports, massive vertical cities grew. The urban areas on Nar Shaddaa were known as vertical cities since new layers of housing and entertainment buildings were built on top of older layers, like Coruscant and another urban world Taris. While much of Coruscant was filled with gleaming apartments and well-maintained skywalks, the entire moon that was Nar Shaddaa was dominated by decaying urban landscape and congested, polluted cities. The moon was protected by planetary shields. Anything illegal elsewhere could be bought and sold on Nar Shaddaa, and many young smugglers, pirates and criminals started their careers on the Smugglers' Moon. Various sections of Nar Shaddaa were controlled by the Hutts and other criminal organizations. Bounty Hunter's Guild
