After the Exarch refuses to stop supporting the Scions, Vauthry boasts that he has already ordered a full-scale assault on the Crystarium with the sin eaters, and the Exarch quickly leaves the meeting. Vauthry disagrees, telling the Exarch that the world is beyond redemption even if the Lightwardens are slain, and that the people of the First require the hand of a God to shepherd them beyond the edge. The Exarch argues that defeating the Lightwardens represents the world's only hope of survival. When the Crystarium's guards begin interfering with Ran'jit's hunt, Vauthry summons the Crystal Exarch to Eulmore to demand an explanation. When Vauthry learns the Warrior and the Scions of the Seventh Dawn are killing the other Lightwardens, he sends his general, Ran'jit, to hunt them down.

He appears before the mayor of Eulmore, taking advantage of the man's desire to keep his position indefinitely by talking him into having his unborn son be infused with the essence of a Lightwarden.
