While discussing these results outside in the Palisades, four members of the group - Malachite, Mara, Raevynn, and Tao - one by one feel an overwhelming urge to relax, settle their roots in the dirt, spead their branches about them, and go to sleep in the warm sun. Each of them is able to fight it off, though, and the feeling does not repeat.
--> The Voice of the Tree is actually the stats for a balor, the nastiest of the demons, with the wood elemental template from the Manual of the Planes slapped on it. I wanted an extremely nasty avatar for the Anchor of Abominations tree, and I got it; by replacing most fire powers with plant powers, and fire spells with plant spells, I was able to make a good villain in a minimum of time. What the party was experiencing was a 9th level spell cast by a hidden VotT, the equivalent to implosion. Instead, it was lignify; if any PCs had failed their save, they would have been killed and instantaneously turned into a tree. Good thing they all rolled high! After the Voice failed at his delaying technique, he snuck away to guard the Citadel.
