Wilhelm's Deep

A huge megacavern in the Underworld that is located roughly between the surface continents Rakshar and Zhanyi. The most noteworthy feature of Wilhelm's Deep is the enormous bottomless canyon system that occupies a majority of the space within. The megacavern is the home of the dybaloth Uau.

Wilhelm's Deep is dark and quiet, and to the unobservant onlooker completely void of life. But even there, in dark crevices and damp walls, lifeforms stir. Pale insectoids and shelled molluscs, among other things, make the canyons and plateaus of Wilhelm's Deep their home.
