Asari Matriarch
"You do not know the privledge of being a mother. There is power in creation. To shape a life...turn it towards happiness or despair...."
Matriarch Benezia is a very powerful asari biotic and spiritual leader among her people. She is also Liara T'Soni's mother, though the two have not spoken in years. When the evidence that proved Saren Arterius was responsible for the Eden Prime attack also proved Benezia was working alongside him, it surprised those who knew her, as Benezia's actions seemed to be completely out of character.
