The Quarren or Qarren (Second Human Empire: Sooi'lijju Xixxi'uhhj), were one of several aquatic sentient species from the planet Dac, called by off-worlders Mon Calamari. The Quarren shared their homeworld with the Mon Calamari, another sentient species hailing from Dac. The Quarren had many conflicts and a tense relationship with the Mon Calamari. However, in order to make their planet prosperous, they were forced to provide resources from the ocean depths so that the Mon Calamari could build star ships for off-worlders.
