Valerian and the City of a Thousand Planets

The Kortan Dahük are humanoid extraterrestrials from planet  Kas-ônar, an intergalactic paradise with three suns. Sensitive to music and sounds, they invented "sound sculptures" with a variety of purposes in mind, such as long-distance communication, healing, or space travel. Kortan Dahük admire humans because their sound sculptures are curiously attractive. Widely considered Alpha's greatest ambassadors, a large number of species settle on Alpha thanks directly to the Kortan Dahük.
