Duren was Ceridus' senator to the New Republic, and later the Galactic Alliance, from 18 ABY to approximately 36 ABY. For the duration of his time in the Senate, as well as a decade afterwards, Duren was a member of a major conspiracy, though this was never brought to the public eye. After the end of his tenure as Senator, he disappeared from the galactic stage until 58 ABY, when he ambushed and subdued the Third Republic's Admiral Phalanx. He then removed, surgically if necessary, many of the components of Phalanx's armorsuit, from which Duren built his own armor. After this, he stole the starship Defiant and became the Chief of Naval Operations for the Golden Empire. He later reappeared as a mercenary, before being taken four thousand years into the future with the party of Toma Branniga
