It is rumored that these caves are the hidey hole of the rogue mosswart Rumuba. Rumors in MacNiall's Freehold suggests that this mosswart may be seeking the help of humans, and he may be willing to reward adventurers that can bring him an item of interest in his studies. The path to find the unusual mossie is not easy though. The tunnels are filled with Mosswart Fanatics, Idolaters, and Soul Trappers.
