Krakalakan, The Forge District
Slaves have been a trade of the Hutts since the slugs discovered other sentient species. Unfortunately, for much of their history they've had many minions willing to work with them to perpetuate it, now though, slavery is a thing of the past on Nar Shaddaa, because Krakalakan is not under Hutt control.
Where once the Ironfur slaves worked the forges for the Hutts, sold to them by the empire, now they work the forges for themselves, fueling an eternal war against the remnants of the empire and the Hutts that finance them.
Krakalakan is safe for any who don't bear the scent of a Hutt, a sprawling and heated district of manufacturing might that has been closed off to the majority of the moon.
