Addy Ingrol, a male Human, served as a Doctor amidst the renewed conflict that pitted the Galactic Republic against the reconstituted Sith Empire.
During the year 3639 BBY, Addy, alongside Asirr, Evad, and Tarkom, lent his aid to Doctor Sannus Lorrick who was conducting experiments involving the rakghoul virus within his laboratory situated on Ord Mantell. Ingrol, along with the other scientists, held the conviction that Lorrick was in pursuit of a remedy for the virus. As the rakghoul virus caused the fall of four Tionese planets, Ingrol and his fellow assistants uncovered Lorrick's actual intentions and endeavored to thwart him; however, they were infected with the virus and subsequently brought under his command. Ultimately, he met his demise at the hands of a strike team that came to prevent Lorrick from infecting himself with the virus.
