Oolin Musters was an alien member of the Alliance to Restore the Republic , who in the year 0 BBY , was imprisoned in a labor camp controlled by the Galactic Empire on the planet Wobani . While in the camp she identified herself to other prisoners as Nail , but instead earned the nickname Kennel , as she hosted various parasite s within a filthy cloth jacket that she used to half cover her chest . The human criminal Jyn Erso was assigned as Musters ' cellmate under the false name " Liana Hallik " , and late one night when Erso woke Musters from sleep by sitting up in her bunk , the alien warned the human that on their next work assignment together she would kill her . The following day , the pair were randomly selected by the guards for the day ' s work shift and removed from their cell to be chained into a turbo - tank used by the camp as a prisoner transport . The alien did not make eye contact with any of the other three prisoners that were accompanying them , which Erso took to mean that Musters would have no allies in her attempt on her life . Musters never had a chance to attempt to kill Erso however , as before the tank reached its destination it was attacked by a squad of Alliance Special forces troopers who were searching for Erso . The rebels quickly blew the door off the vehicle , shocking Musters , and killed each of the three stormtrooper s guarding the prisoners . They then freed their target , who hit Rebel Sergeant Ruescott Melshi with a spade and promptly tried to escape from her saviors , fleeing past Musters as the alien stood up . Erso made it out of the tank before being stopped by the reprogrammed KX - series security droid K - 2SO . Erso was then taken back to the Alliance ' s base on the moon Yavin 4 . Musters was then able to escape from Imperial custody as well and made her way to Jedha City on the moon Jedha . While in one of the city ' s streets she and other civilians had to stand aside to allow an Imperial patrol including a " Occupier " combat assault tank to pass by . As the patrol passed by Musters it was attacked by members of the rebel leader Saw Gerrera ' s partisans , causing most civilians in the street to flee . Shortly after this attack , Jedha city was destroyed by the Empire ' s Death Star superweapon . Personality and traits . Oolin Musters was a member of a bipedal alien species with gray and brown leather y skin and tentacles protruding from their pinched , worm - like faces . Her cellmate Jyn Erso never bothered to learn Musters ' real name , species or gender , but used female pronouns to describe the alien . Musters moaned and wheezed while she slept , and while awake spoke with a voice that sounded like claws on a slate . When Erso woke late at night causing Musters to also wake , the alien told her cellmate to go back to sleep and then asked her if she wanted a warning before she was killed . Despite Erso claiming she did not want a warning , Musters informed her of her plans for murder anyway , claiming that she liked a quiet cell when Erso pointed out that the alien would miss her company . When Erso asked , Musters claimed that she had always been the way she was while imprisoned , even as a child . Behind the scenes .
