Publisher's blurb:

A Starfinder Society Quest designed for levels 3-6 (subtiers 3-4 & 5-6).

The Triaxian city of Cadascon fell into ruin during the events of the Gap and since that time explorers have sought to uncover what happened. Finally, after centuries of trepidation by other organizations, the Starfinder Society has assembled a great expedition to inspect the outer edges of the devastated landscape. What horrors lie hidden past the borders of the sulfurous city and what power does its mysterious crystals portend for the future of Triaxus?
