Denathrius however, was working WITH the Jailer, and keeping all that anima to then deliver into the Maw for the Jailer. He was still not receiving any new souls from which to get Anima - But that didn't stop him from taking anima from the souls already there. He just refused to use it for Revendreth, as it was supposed to be used, causing the same drought as everywhere else despite ways that they could have worked around it.
