From publisher blurb:
The Jail of Gundavold is a scenario designed for a solo player but adjustable enough for a party size if needed. After a foray into the wilderness Ruins of Borgdell, you found yourself ambushed with a bag tossed over your head. After a grueling trek across uncertain terrain you find yourself in jail. Are you smart enough to get yourself out of this mess?
This is not your typical dungeon crawl and should be careful read a few times before attempting to run it. While no DM (or author) can cover every idea a player comes up with, multiple avenues have been addressed in this offering. Remember creativity should be rewarded appropriately!
This adventure setting was designed for 5th Edition AD&D for the Filbar Campaign for a lower level solo adventurer and DM.
