Asirr was a Human female who served as a doctor during the period of the Galactic Republic's renewed war against the Sith Empire that had been rebuilt.
In the year 3639 BBY, Asirr, together with Addy Ingrol, Evad, and Tarkom, gave aid to Doctor Sannus Lorrick as he conducted experiments involving the rakghoul virus within his laboratory, which was located on Ord Mantell. Asirr, along with the other scientists, had the understanding that Lorrick was trying to find a way to cure the virus. After four planets within the Tionese planets succumbed to the rakghoul virus, Asirr and the other assistants found out what Lorrick was truly planning and tried to put a stop to him, but they ended up being infected with the virus and were controlled by him. Later, she met her end when a strike team arrived to prevent Lorrick from infecting himself with the virus.
