From publisher blurb:
Filbar Friday this week brings you OP1 - Vengeance of the Minotaur! This single page adventure can be for a single, 6th level PC and DM or a group of lower level PCs and DM. Information has come to the ear of the PC(s) that a Bull Cult has taken up residence in a nearby cult. While the group doesn’t cause any problems, a mysterious stranger showed up in town looking for them. The citizens didn’t find the person’s arrival as a positive thing and want someone to investigate. A one page dungeon entry, it is easily customized to suit your campaign for a solo player or a small group! As with all 1st of the month entries…it is free!
This adventure setting was designed for 5th Edition AD&D for the Filbar Campaign for a 6th level character and a DM.
