Duke Vox is the captain of Airyglyph's Dragon Brigade and the main antagonist for the early portions of Star Ocean: Till the End of Time. A manipulative man, he wants to keep the war between Aquaria and Airyglyph going for as long as he can. He has the power to issue royal commands as well. He is the head of the Peacekeeping Force that reported and arrested the Church of Apris members that were supposedly planning to assassinate the King.
It was because of Vox that the war between Airyglyph and Aquaria lasted as long as it did, with Vox constantly pushing for more attacks, despite the objections of Count Woltar. However, since Vox was the King's uncle, his advice took precedence over all others.
After Albel let the party escape from the Kirlsa Training Facility and failed to stop them from taking the Copper Ore, Vox ordered that he be put in the dungeon for treason.
Eventually Vox started the push towards Arias, taking the entire Airyglyph army with him. The party confronted him in the hopes that would stop him, but just as they were about to finish him off a laser strike from a Vendeeni cruiser killed him instantly.
And he is voiced by Ian McKellen in the English dub and his Japanese voice is unknown.
