He wore a white - jacketed uniform . Biography . Ronnadam was an Imperial Security Bureau Captain during the Age of the Empire . During the secret mission to Tatooine prior to the Battle of Yavin , Ronnadam was stationed aboard the " Imperial I " - class Star Destroyer " Devastator " . He was in his office when Lieutenant Ciena Ree handed him data packets taken from Prince ss Leia Organa ' s captured CR90 corvette " Tantive IV " . Ronnadam , who was preoccupied with his monitor , took the packets without glancing back at her . Grand Moff Wilhuff Tarkin was present in the room via hologram and chastised Ronnadam for his lax protocols while complimenting Lieutenant Ree for her diligence . After the TIE fighter pilot Thane Kyrell disappeared from his posting on the planet Kerev Doi , Captain Ronnadam questioned Thane ' s friend Nash Windrider about Thane ' s loyalties and political beliefs . Nash told Ronnadam that Thane was not a rebel but the ISB officer was dissatisfied . The now Lieutenant Commander Ciena , who was Thane ' s lover , visited Ronnadam to reassure the ISB officer that her friend was not a traitor and that he had expressed deep sorrow and anguish about the destruction of the Death Star . Ronnadam was unsympathetic to Ciena ' s explanation that Thane was reacting to despair and charged him with ensuring that Lieutenant Kyrell returned to active duty . When Ciena suggested that Thane had returned to his homeworld of Jelucan , Ronnadam ordered Ciena to travel to the planet on the next transport . He told Ciena that the ISB was preoccupied with other matters and could not spare personnel to question Thane . He ordered Ciena to search for him and to investigate any reports of Thane ' s involvement with the Rebel Alliance . Ciena found Thane on Jelucan but was unable to convince her friend to return to Imperial service . Instead , she fabricated a report that Thane had committed suicide by throwing himself from a high cliff ; being unable to cope with the death of his comrades aboard the Death Star . Ciena delivered the report to Captain Ronnadam . When Ciena explained the Jelucani custom of sky burials , Ronnadam derided it as a barbaric custom . Since Ronnadam was preoccupied with more pressing matters , he accepted her report and listed Thane as dead . Ronnadam was later posted aboard the " Executor " - class Star Dreadnought " Executor " . Following the Escape from Cloud City , Ciena visited Ronnadam and sought permission from the ISB officer to visit her homeworld in order to support her mother Verine Ree , who was on trial for embezzlement . Ronnadam was unsympathetic to Ciena ' s plight and reminded the officer that the charges against her mother had been brought by the Imperial authorities . Ronnadam allowed Ciena to take leave after she explained that she wanted to investigate the matter for herself . Before leaving , he reminded her to report on the verdict of the case . Ciena traveled to Jelucan to support her parents during the trial . Due to the trumped up charges , Verine was convicted of embezzlement and sentenced to six years of hard labor . Following the trial , Ciena reported to Captain Ronnadam . Despite being dissatisfied with the verdict , she reported that she was satisfied that justice had been delivered . Ronnadam expressed surprise that Ciena accepted the verdict . He remarked that she had used up two weeks ' leave , but that her record was still unblemished and told Ciena that she could expect a promotion in the future . Ronnadam ' s prophecy was proven right , and Ciena was promoted to Captain shortly before the Battle of Jakku . Personality and traits .

Ronnadam was brusque and quick tempered man who had a habit of interjecting and raising his voice when questioning Imperial personnel like Ciena Ree . Grand Moff Wilhuff Tarkin had a dim view of Ronnadam for his bad manners and lax attention to protocol . As an ISB officer , Ronnadam was concerned with rooting out any rebels and rebel sympathizers from the ranks of the Imperial Military . He regarded the Jelucani custom of sky burials as a barbaric custom .

Ciena regarded him as a hypocrite for forcing her to lie that justice had been delivered in the case of her mother Verine , who was wrongly accused and convicted for embezzlement .
