Mass Effect 3
Dr. Liara T'Soni is an asari information broker with a background in scientific research on Prothean technology. Born on Thessia in 2077, she is the only child of the late Matriarch Benezia, although mother and daughter became estranged in the years before Benezia was indoctrinated by the Reaper known as Sovereign. T'Soni is also a highly trained biotic who served under Commander Shepard aboard the SSV Normandy before the ship was destroyed in a Collector attack.
Before she became involved in galactic affairs, Dr. T'Soni spent 50 years researching the Protheans' technology and the mystery of their extinction. She now divides her time between uncovering Prothean ruins and consulting with noteworthy representatives of the various Council races.
