A long-lived, mysterious little species with an impressive memory and a homeworld located along a fairly popular trade route.
Xendekian
A peaceful people whose mythical "bird of fortune" was temporarily abducted by the Empire, resulting in a potentially prolonged conflict once the avian was returned.
Trome
The Star Wars equivalent of "Gnomes" who, of course, could be found dwelling on the Forest Moon of Endor, like so many other mythical-like beings within the franchise.
Gorum
A little known species that seems to have lizard, rat, and even ape-like traits, although given the limited illustrations we have of them (specifically only one) it's hard to infer more.
Taymar
A four-armed, glittery species whose natural Force abilities allowed them to levitate on command, while their hair forever floated above them in a unique but potentially bothersome display.
Warthog
We know next to nothing about this species at present, including whether or not "Warthog" is their real, actual name.
Kerrakk
Insectoids who owned and operated a low level criminal enforcer gang operating out of Burnin Konn prior to Operation: Cinder.
Atoan
A Human-passing species who, instead of having one central heart, have thousands of miniature hearts found throughout every inch of their internal structure.
Ultaarian Greenback
Seemingly parts humanoid, rhinoceros, and armadillo, these four-armed hulks have all the brute strength without any of the fortune a name like "Greenback" would commonly infer to us.
Hoover
Miniature vampiric pachydermoids who are hyperintelligent, yet often take on a much more unassuming demeanor to get them within close proximity of oblivious, slumbering prey.
