Forsaken Mountain (5E)

From publisher blurb: Coburg the Undying, Master of Aufstrag, has sent forth his servants to find and bring the Vessel of Souls to him. To stop him one must travel far beyond the realms of man and cross over into the lands of dreams and thence into the realms of the forever dying, where creatures both horrifying and ambrosial dwell. Fear will certainly be your undoing. A mid-to-high-level adventure for a party of 3-6 characters. Play as stand-alone or part of a larger series.
