Hailing from the Outer Rim world of Kallidah, they are more appropriately named Kallidahin, though to the galaxy at large they are known as Polis Massan after their vast and intricate archaeological digs on the asteroid that bears the name, where they have searched for centuries for a link between their race and an enigmatic extinct species known as the Eallayin. Though the vast majority of them are born without vocal chords, some are born with the rare gift. Regardless of the auspice of their birth, all have a natural telepathy that allows them to communicate with each other and other living beings. Polis Massans also begin play with natural aptitudes in Medicine. They can be found in the Strongholds of Resistance sourcebook.
