Frax was a Kajain'sa'Nikto individual of male designation, existing within the galaxy. Due to the Millennium Falcon carrying two tons of Cordaxian ore, Han Solo abandoned him in the Cordaxian Sea on Odona during a pursuit by TIE fighters, effectively leaving him for dead. Solo discarded Frax, along with the ore, into the Cordaxian Sea. Subsequently, the Empire captured and enslaved Frax, forcing him to work on the planet.
Following a Rebellion bombing raid targeting Imperial units along the Cordaxian Sea coastline, a member of the Rebel Alliance discovered him. Frax eliminated the Rebel, then undertook a four-month voyage across the sea. He later employed mercenaries Selt and a droid in an unsuccessful attempt to assassinate Solo and Leia Organa during their mission to Odona. Upon Selt and the droid expressing their intention to desert him, Frax killed Selt and destroyed the droid. Departing the cave he occupied, he pursued Han and Leia, ultimately meeting his end in a snowstorm, his corpse frozen while aiming to shoot Organa.
