Tivik was a human male who served on Jedha as one of Cassian Andor's underground contacts to the insurgent group led by Saw Gerrera. During a secret mission on the Ring of Kafrene, Tivik was responsible for informing the Alliance to Restore the Republic of the Empire's secret superweapon, the Death Star. After Tivik and Cassian's meeting was interrupted by Imperial Stormtroopers, a brief firefight broke out. Tivik could not escape due to his wounded arm, so a reluctant Cassian killed his friend so Tivik could not be captured.
