Alien

"Alien" was a general-purpose term used in the galaxy by humans and even some droids to refer to anyone of a sentient species that was not a human. Sometimes, the term nonhuman was used interchangeably. To the Chiss, the term was used to describe non-Chiss species, as well as by the Kilji to refer to non-Kilji. There existed within both the Galactic Republic and Galactic Empire a set of Unknown Alien protocols that governed official encounters with unknown alien species. Species that resembled humans, like Kiffar, were referred to as "Near-humans."
