From publisher blurb:
Wise and powerful individual through the world seek knowledge. In and of itself, this is not necessarily a bad thing. In and of itself, this is not usually a dangerous endeavor.
When the road leads to the disembodied head of a demon, however, it can not only prove foolish, but possibly deadly. Deep within Hallerie Glen, the road leads straight to Aumetillien, the Demon Head.
Within these pages, you will find the information you need to run an encounter with Aumetillien, as well as information about Hallerie Glen and those other creatures that inhabit the valley.
