Liara T'Soni is an asari scientist, voiced by Ali Hillis, that joins Shepard's squad in the first game and appears in "2" as a non-player character (available as a temporary squad member in "") and as a full squad member in "3". She is one of the experts on Prothean history and technology. Liara is a potential romance option for Shepard throughout the entire trilogy. Following Shepard's death in "Mass Effect 2", Liara gradually became emotionally hardened, and began working as an information broker, eventually leading to the events of "Lair of the Shadow Broker" where she becomes the new Shadow Broker at the end of the DLC.
