Characters explore its dangerous halls, uncover remnants of the past, and search for hidden riches while confronting the mysteries surrounding those who entered and never returned. The adventure can be run as a standalone scenario or used as a sandbox in the default setting. It is written for Castles & Crusades, with guidance for adapting it to other OSR systems.
