Milton Trayx

Milton Trayx, General in Chief of the Haddron Armed Forces was the leader of Haddron after Hans Kesar's demise. Instead of an empire, he made Haddron a Republic. His wife was Helena Trayx. He did not know she was cheating on him.

He came to the fortress prison on the outskirts of Haddron to see Kesar and his second-in-command, Cruger. On their arrival, he became friendly with the Doctor,  Jamie and  Victoria. When the VETAC robots arrived, he helped to fight alongside the Doctor, Prion and Kesar. He knew all along that Kesar was not himself, but Gerhart Rutger. (PDA:  Dreams of Empire)
