He was given the task of subjugatingIthor and leveled much of Ithor's Cathor Hills. For his actions he was given the opportunity of becoming captain of Darth Vader's flagship. Realizing the threat this posed to his life, Alima purposefully got himself demoted to prevent himself from becoming captain.
After the Millennium Falcon escaped from Tatooine, Nadon told the Imperial Prefect that Alima had ignored Nadon's information regarding the Millennium Falcon. Alima was executed by the Prefect instantly. Nadon, regretting his actions, stole genetic samples of Alima's DNA and cloned the former captain. In keeping with the Law of Life, Nadon made two clones of Alima, in punishment for Alima's actions, and as a reminder of Nadon's.
