Dr. Liara T'Soni is an asari researcher who has spent the past fifty years of her life studying Yuuzhan Vong technology and culture. She was born on Thessia, making her "only" 106—little more than a child in asari terms. She already has a great deal of insight into the Yuuzhan Vongs and is a highly trained user of biotics.
The only child of Matriarch Benezia, Liara was raised by her mother alone. She knew little of who her father was, only that it was another asari. Liara is a pureblood, a fact she speculates to be a reason why her "father" seemingly did not wish to be identified.
From an early age Liara became fascinated in the Protheans, seeing them as wondrous, mysterious figures. Growing up, she did not relish her role as Benezia's daughter and has shied away from her mother's life as an important figure in galactic affairs. Benezia's position meant Liara faced high expectations from everyone. Liara chose a career in archaeology to indulge her interests and to escape the pressures of being the daughter of such a prominent figure. Because of her work, Liara spent most of her time in content solitude.
