B'omarr Order

The B'omarr Order, which consisted of B'omarr monks, was a religious order that believed in isolating themselves from all physical sensation to enhance the power of their minds. To that aim, enlightened monks had their brains transplanted into nutrient-filled jars. Whenever they wanted to move, those bottled-brains used spider-like droid walkers. Older monks used four-legged walkers, but younger monks used a six-legged variant.

The order possessed multiple regeneration gems, which at the time of Jabba the Hutt were stored underground behind triple doors.
