The Quarren are an intelligent humanoid species whose heads resemble four-tenticled squids. Having leathery skin, turquoise eyes and suction-cupped fingers, this amphibious species shares the world of Calamari with the sad-eyed Mon Calamari, living deep within their great floating cities. Some people call these beings by the disparaging term "Squid Heads."
The Quarren and the Calamarians share the same homeworld and language, but the Quarren are more practical and conservative in their views. Unlike the Mon Calamari, who adopted the common language of the galaxy, the Quarren remain faithful to their oceanic tongue. Using Basic only when dealing wth offworlders.
Many Quarren have fled the system to seek a life elsewhere in the galaxy. They have purposely steered clear of both the Rebellion and the Empire, opting to work in more shadowy occupations. Quarren are found amongpirates, slavers, smugglers, and within various networks operating throughout the Empire. |
