FYI- Tsagoth is the undead demon. Bareris and Winddancer followed the pair into the water and resumed their attack on Tsagoth until the undead demon was forced to magically transport himself to safety. Although Bareris hurried to get Tammith out of the water, he did not make it in time and his beloved perished. Bareris was anguished over Tammith’s death, and after Aoth told him of his findings about the dream vestige’s nature, the bard set out in a little boat to confront the entity. Although the dream vestige engulfed Bareris, he managed to destroy the fog-like creature with his bardic power.
