Kessel

"We'll be sent to the spice mines of Kessel, or smashed into who knows what!"

- C-3PO Kessel was a planet that contained the spice mines and hosted major mining facilities.

History
Many organizations such as the Pyke Syndicate, dealt with spice mined from Kessel, utilizing smugglers and freighter captains to deliver it to the crime families of Coruscant making them rich on the Black market.

The Galactic Empire operated a mining operation, employing numerous slaves, including Wookiees, to harvest spice. Meanwhile, the Kessel royal family lived in lush sanctuaries in the planet's southern hemisphere, turning a blind eye to the brutal working conditions in the mines of the northern hemisphere.

Two Years after the Great Jedi Purge and Order 66, Jedi survivor Eeth Koth had arrived on the planet as a freighter captain working temporarily for credits to transport spices from Kessel to Coruscant.
