A mammoth, mostly stone structure on the edge of Tatooine's sandy Dune Sea, the palace of crime lord Jabba the Hutt is a crossroads for the scum and villainy of the galaxy. Jabba seems to be constantly entertaining other criminals, bounty hunters and assassins, putting out lavish spreads and providing all sorts of entertainment, from jizz bands to executions.
Many centuries ago, exiled monks of the B'omarr order built what was then a huge monastery on the edge of the Dune Sea. The bandit Alkhara took up residence in part of the monastery and remained there for 34 years, raiding nearby moisture farms while expanding and improving the citadel. The B'omarr monastery was the home of many other gangsters and bandits until eventually becoming the palace of Jabba the Hutt, who has expanded the stronghold to encompass a hangar for his ships and Sail Barge and repair facility.
Throughout the changes, the B'omarr monks have kept to their own affairs in the palace's lowest levels, trying to reach a level of enlightenment at which their brains can be surgically removed by the other monks and placed in nutrient-filled glass jars, freed from the distractions of the flesh.
