Twi'leks are tall, thin humanoids with skin pigment that spans a rainbow of colors. Their most distinctive feature is a pair of shapely prehensile tentacles that grow from the base of their skulls.
Few things are as graceful as a female Twi'lek in motion. This beautiful image has forever doomed generations of young Twi'leks into servitude, as the wealthy and corrupt have taken to brandishing Twi'leks as badges of prestige.
In the waning years of the Republic, the Twi'lek homeworld of Ryloth was represented in the Galactic Senate by the corpulent blue-skinned politician Orn Free Taa. Even a politician of high office was not above flaunting a pair of lovely Twi'lek aides as a sign of influence and wealth.
