But while Rook, Dire Wolf, Matterhorn, and others try to save the planet, rogue wardens such as Stag and Arachnid stand in their way--each with their own reason. As the stakes rise and the world continues to crumble, Rook and company uncover their adoptive world's secrets and encounter more danger than they ever imagined. Collects Rook: Exodus #7-12.
