Publisher's blurb:
A Pathfinder Society Quest designed for 1st- through 4th-level characters, playable in 2-3 hours.
A group of powerful Pathfinders had to abandon the exploration of an underground complex after defeating a powerful lich and stopping a devastating ritual by the skin of their teeth. The PCs are tasked with exploring this complex now cleared of threats and cataloguing what's there. The ritual, though, while incomplete, has still linked the site to its counterpart in the Netherworld, and once they enter the PCs find that their task will not be as simple or boring as promised, as they have to fight through the shadowy mirror of the Netherworld complex just to get back home, with unknown threats that most assuredly were not cleared out.
