Maria Traydor

She is an enigmatic young and beautiful human girl who is rumored to possess some very strange powers. Orphaned at a young age, she somehow became attached to Quark, an anti-Federation organization most active in the Klaus System, through those having saved her after her mother's death. Although she is an Earthling, her impeccable integrity led the anti-Federation organization Quark to make her their leader.

Now as its leader, she is using the group's resources to help her to discover the origin of her powers, leading her to the need to find Professor Robert Leingod and his family. This search forces her to send her friends and coworkers, Cliff Fittir and Mirage Koas, out to find Fayt Leingod. She is the voice of reason in most situations and tends to be rather blunt.
