Adin was an Ilari and the physician to the tyrant Tieran.
In 2373, Adin, Tieran, and a female named Nori were beamed aboard the USS Voyager just before their ship exploded. The Doctor and Kes were unable to save Tieran, who died of his injuries, but not before he transferred his consciousness into Kes.
Kes/Tieran became paranoid due to the stress of the mental conflict between their minds. Adin tried to convince Tieran to break control over Kes and transfer to a new host. He was fearful that there would be irreversible damage done to his mind if he did not. Tieran ended up murdering Adin using Kes' mental abilities. (VOY: "Warlord")
Adin was played by actor Anthony Crivello.
He filmed his scenes between Friday 30 August 1996 and Friday 6 September 1996 on Paramount Stage 8, 9, and Paramount Stage 16.
His two costume jackets from this episode were later sold off on the It's A Wrap! sale and auction on eBay. [1](X) [2](X) [3](X)
