Livin' on the Edge
The largest moon of Nal Hutta, once resembled the planet it orbited, with boundless jungles and the bluest oceans. Those features disappeared within centuries of the Hutts' appearance in the Y'Toub system. Over the centuries Nar Shaddaa became a city from pole-to-pole, so overbuilt with spires and spacedocks that residents refer to it as "Little Coruscant." No matter how close it is to the system's sun, Nar Shaddaa seems to be in a state of perpetual gloom, smogged over from engine exhaust and refueling depots. It has become the perfect place for Hutts to conduct their shady deals.
Smugglers come to Nar Shaddaa in droves, looking for employment, gainful or otherwise. Every Hutt has a scheme, and their up-front pay, meager though as it may seem, can be tempting to those down on their luck.
