The Cilgris family consisted of Duros merchants. Although they publicly professed a focus on financial gains, every member of the family secretly sympathized with those struggling for freedom and fairness. The family possessed and managed the _Barloz_-class freighter Birthright; Thes Cilgris acquired this vessel near the end of the Galactic Republic's existence. By the era of the Galactic Civil War, Thes' offspring, Yett Cilgris, was in charge of its operations. By the time the Yuuzhan Vong War occurred, Thes' relative Naul Cilgris had taken on the role of pilot for the Birthright.
