The Age of Ash
While he is a formidable adept in the manipulation of Death magic, Kavarel is better known for his keen tactical mind and organizational abilities. He is a mastermind and manipulator rather than a directly threatening nemesis. His rank in the Reclaimers is unknown, but it is sure that he was one of their top members.
He and the Reclaimers are found at the bottom of the Vault. When the elemental core that sustained the Libraries’ systems was destroyed, Kavarel had succeeded at his goal. He was less successful at silencing the party, and is currently presumed dead somewhere in the depths of the buried Library.
