Zvolhg is a high-ranking officer of the ProtoVordartrian Empire. During the Galactic Civil War, he served as a General. Later, he was promoted to the rank of Grand General.
Zvolhg was not one to underestimate his opponents, usually expecting them to send more than what they actually would. In the case of his mission on Chorax to capture the Nonnah, he had his Sentinel landing craft modified with special armour and heavy shielding, knowing there would be heavy resistance from both the Galactic Empire that had been sent to destroy the crashed ship, and the Rebel Alliance whom had sought to recover both the crew and the stolen equipment.
