Tumaz'mor'diamir, also known as Azmordi (core name), was a male Chiss serving in the Chiss Expansionary Defense Fleet. He held the rank of Lieutenant Commander and fulfilled the role of helm officer on the vessel Springhawk.
Serving as the helm officer and holding the rank of Lieutenant Commander, Tumaz'mor'diamir (Azmordi) expressed his doubts regarding Thrawn's choice to disclose critical information to individuals outside the military hierarchy, specifically sky-walkers and their guardians, within a quadruple star system situated between Rapacc and the Chiss Dioya system. Thrawn justified his decision by emphasizing that caregiver Mitth'al'iastov (Thalias) and sky-walker Che'ri were integral members of the Springhawk's crew, underscoring the necessity of their understanding the mission's objectives.
