Kingdom of the Blind - Episode Four: Snakes Alive!
Kingdom of the Blind is a short adventure for four 8th-level characters. The adventure is set in a minor duchy that is fairly removed from the ruler of the land. As a result, trouble can brew in the land and the king would not know immediately.
The PCs faced all manner of fungus last time. Perhaps with a little more investigation, they'll discover what's really going on with Zhanna and Dephyl.
