Kallidahin

The Kallidahin were a species of humanoids that lacked facial features. Although they originated on Kallidah, they also established their presence in the asteroid field of Polis Massa, and they came to be known as Polis Massans. Kallidahin were typically silent, communicating only through telepathy. Though rare, some did have vocal chords and were capable of speech despite lacking a visible mouth.
