Zyphur River was written by Jim Jacobson who also wrote Cave of the Mind. A famous scientist, Professor Axom, has been kidnapped and SFPOS (The Society for the Preservation of Scientists) is offering a reward for the safe return of the professor. It is rumored that the infamous Black Warrior is responsible for the kidnapping and that he lairs somewhere along the Zyphur River. You must traverse the river, find the professor, and bring him back alive.
The map is large with almost 70 different locations to explore.
