Twi'leks are tall, thin humanoids, indigenous to the Ryloth star system in the Outer Rim. Twin tentacular appendages protrude from the back of their skulls, distinguishing them from the hundreds of alien species found in the known galaxy. These fat, shapely, prehensile growths serve sensual and cognitive functions well-suited to the Twi'leks murky environs.
Capable of learning and speaking most humanoid tongues, the Twi'leks' own language combines uttered sounds with subtle movements of their tentacular "head tail," allowing Twi'leks to converse in almost total privacy, even in the presence of other alien species. Few species gain more than surface impressions from the complicated and subtle appendage movements, and even the most dedicated linguists have difficulty translating most idioms of Twi'leki, thw Twi'lek language. More sophisticated protocol droids, however, have modules that do allow quick interpretation. |
