From publisher blurb:
Forgotten deep in a forest so ancient even the druids cannot recall its full history lies a crypt dedicated to a forgotten hero. Little of the hero is known, merely rumors of rumors, legends of legends, and scraps of tales woven through bard song for centuries. The journey through dusty library tomes to silent monastery records to half-burned tapestries, marginalia, and occult inquiries has been painstaking and expensive. But if such finds were less difficult, less rare, then someone would have already found it. There is ancient treasure to be had - artifacts from a time of lost magic and craft that have not seen the light of day for centuries. The only challenges are anything and everything an age of master crafters and casters have thrown in the way.
Are your adventurers up to the task?
