Vedij held the position of Supreme Chancellor within the Galactic Republic in 3017 BBY, during the Seventeenth and ultimate Alsakan Conflict. This conflict saw the Republic's capital world, Coruscant, clash with Alsakan and their allied forces. Throughout the Alsakan Conflict, Vedij's Republic Navy possessed a more substantial industrial capacity. This enabled the Republic to construct an Invincible-class fast battleships fleet intended to overwhelm the forces of Alsakan and Corulag. However, even with the Invincible-class ships, the Seventeenth Conflict concluded with a win for Corellia, whose long-range frigates fleet, created as a response to the Coruscant-Alsakan conflict, proved superior to the Republic's forces.
Vedij is referenced within The Essential Guide to Warfare, a reference published in 2012 and authored by Jason Fry alongside Paul R. Urquhart.
