The Poss'Nomin were a race of mammalian humanoids native to the planet Illarreen. They were distinguished by its three eyes and shovel-like jaws. They were discovered about 100 years before the Battle of Yavin by a spice trader who decided to investigate Illarreen. Their civilization had developed to the point that their nations had started warring against each other when the planet was discovered by spice traders. The Poss'Nomin ceased their fighting to communicate with the off-worlders, and soon discovered that there was much more to worry about than their petty squabbles. The Poss'Nomin put down their weapons and began to integrate themsevles into the galactic culture. The warring nations collapsed their boundaries and joined to form a single, planetary government.
