Aria T'Loak

Mass Effect 3 Codex Entry
A powerful biotic, Aria T'Loak has been the sole ruler of Omega for some time. Rumored to be at least a thousand years old, she is as skilled at combat and the use of her biotic abilities as she is at manipulation and power games. Ruthless, highly intelligent, and dedicated to maintaining her rule over Omega, Aria is a force to be reckoned with.

Though recent events have seen Cerberus take over Omega and send Aria into exile, there is no doubt that Aria will do everything within her power to reclaim what is hers.
