Dr. Liara T'Soni is an asari researcher who has spent the past fifty years of her life studying Prothean technology and culture, specialising in the Prothean extinction. She was born on Thessia in 2077, making her "only" 106 — little more than a child in asari terms — when Mass Effect takes place. She already has a great deal of insight into the Protheans and is a highly trained user of biotics. She is a potential romance interest for either a male or female Shepard.
Liara T'Soni is voiced by Ali Hillis.
