Allies of the Ghasts of Leng. The kaveph are massive creatures that originate from the lightless underground of the Plateau of Leng. They are usually found in the company of the greater ghasts of Leng, acting as powerful allies as the greater ghasts try to overtake prey. The kaveph are seen as expendable by the ghasts of Leng, and they are often sent in first to try and soften up more powerful enemies before the ghasts swarm in to devour them.
