Morish

The Morish were a short, furry, loud-voiced species from the planet Morishim, near what eventually became the Imperial Remnant. During the rule of the Galactic Empire, the Imperials set up a secret communications center in a cave on Morishim. After the Empire pulled out, a Morish known as the Old Recluse found the abandoned communications link, and used its newsfeeds to fool others into believing he had clairvoyant abilities.

Morish were perfectly capable of speaking Basic, but those Morish who did speak Basic often pretended not to.
