Monolith of the Underworld

A roleplaying adventure for mid-level characters, set in open grassland where fertile land abruptly gives way to a barren waste. The party encounters a strange boundary curving outward from a monolith, where even a small insect suffers violent convulsions after crossing. They investigate the unnatural phenomenon and its connection to the monolith.
