Rotmire Creed from Warcry
The swampy depths of this inhospitable place are home to the Rotmire Creed, a group of twisted alchemists who worship Lord Leech. Their Plague God rewards them for their adoration by blessing them (and their enemies) with maladies and diseases. They come to the Gnarlwood seeking the Eye of Chotec so they can poison its geomantic engines and transform the entire forest into a diseased swampland.
