Stool is a young myconid who is a prisoner of the drow because he was previously captured by Sarith Kzekarit. Stool using telepathic spores to communicate with the other prisoners, eagerly acting as a conduit for others to talk if they do not share a language. He becomes quickly attached to those who treat him nicely and acts much like an enthusiastic younger sibling. He believes that his people, led by the great and powerful Sovereign Phylo, will be able to help you and your group reach the safety of the overworld.
