Liara T'Soni

Dr. Liara T'Soni is a fictional character in BioWare's Mass Effect franchise, who serves as a party member in the original Mass Effect trilogy. She is an asari, a female-appearing species from the planet Thessia who are naturally inclined towards biotics, the ability to "manipulate dark energy and create mass effect fields through the use of electrical impulses from the brain". Within the series, Liara is noted for being the galactic scientific community's foremost expert in the field of Prothean archaeology and technology, specifically evidence concerning the demise of the ancient Protheans, believed by the galactic community to be the pre-eminent civilization in the Milky Way galaxy until their sudden disappearance fifty thousands years before the events of the first Mass Effect.
