This planet is home to both the Mon Calamarians and the Quarren, both water-based species. The planet itself is almost all water. Mon Calamari was the name given to the planet by Human explorers from the Galactic Republic who first discovered and revealed the world to the rest of the galaxy. The native species referred to the planet as Dac.
This planet was the home of Admiral Ackbar, who decided to venture out into the stars. Since then, Dac has developed its own fishmonger busniess and is also the base of operation for Admiral Snackbar Inc.
It is a popular tourist destination for travelling Hanar, as they prefer the oceanic environment, and they have good relations with the Mon Calamari.
