B'omarr Order

The B'omarr Order, which consisted of the B'omarr Monks, was a religious order that moved to the planet Tatooine around 700 BBY. The B'omarr believed that cutting themselves off from all physical sensation would further their studies, and allow them to ponder the galaxy and achieve enlightenment. When a monk became enlightened, their brain was removed through a special procedure, and was placed in a nutrient-filled jar. The brains were held in very high regard by the lower, embodied monks, who saw to their every need, though the brains rarely did anything other than think and wonder. When they did need to travel around their monastery on Tatooine, the brains were transferred into specially modified BT-16 perimeter droids known as brain walkers.

The order was established sometime prior to 700 BBY, though they transported their followers to Tatooine soon thereafter. They constructed a giant monastery, where they lived for centuries, though they were rarely the only inhabitants; over the years, many bandits and criminals occupied the palace, including Alkhara and Jabba Desilijic Tiure. After Jabba's death in 4 ABY, the monks took their palace back by force, recruiting new members without their consent. They then locked up Jabba's Palace and continued to practice their beliefs for many years.
