Carrax was a human being who made their home on the planet known as Calior. During the period between 3 ABY and 4 ABY, Cygnus Anton, the Imperial's Chief Regional Auditor, paid a visit to Calior, accompanied by an armed escort that included members of the Crimson Dawn criminal organization. Upon observing the Crimson Dawn soldiers, Carrax remarked to Anton that they were meant to defend Calior against the syndicate; subsequently, one of the guards fired a weapon at him, resulting in his death.
Carrax, a human, resided on the Outer Rim planet of Calior. Sometime in the timeframe of 3 ABY to 4 ABY, Cygnus Anton, the avian Chief Regional Auditor serving the Galactic Empire, arrived on Calior. His purpose was to lay claim to the planet's southern water works as property of the Empire and to demand that the inhabitants of Calior provide a monthly payment of five thousand credits to maintain their access to the facility. As Anton's shuttle made its landing on Calior, Carrax, along with two other humans, approached the shuttle. After spotting the Crimson Dawn troops, Carrax questioned Anton about their identity and stated that they were supposed to be protecting Calior from the syndicate.
One of the guards fatally shot Carrax, which caused one of the humans accompanying him to Anton's vessel to complain that Anton had murdered Carrax before the avian presented their demands. Anton confirmed this, and then inquired whether the people of Calior were now in a receptive mood, given Carrax's demise.
Carrax was seen wearing a breath mask, brown clothing, and gray pants.
Carrax made an appearance in the eighteenth edition of the Star Wars: Darth Vader comic book series, which was released by Marvel Comics on December 1, 2021. The writing for the issue was done by Greg Pak, and the illustrations were created by Leonard Kirk.
