Down the Shadowvein
An OSRIC adventure module for characters of levels 3–5, designed for six to ten sessions. The party loads canoes and travels along the fast-moving Shadowvein, an underground river leading into unexplored caverns. Maps may prove unreliable, requiring exploration, problem-solving, and combat as the journey continues. The adventure follows Pod-Caverns of the Sinister Shroom but can also be played independently, and leads into The Mouth of the Shadowvein.
