This submission oozes theme! The combination of late middle ages and the pack of cards is a fantastic marriage, as they were introduced to Europe in about this time period. I'm sure this was intentional, just wanted to say it didn't go unnoticed.
The brief mentions of the supernatural (demons, necromancy, clairvoyance) juxtaposed against the more familiar backdrop of the late middle ages get the gears in my brain grinding, as do the suggested adventures.
I'm excited to bring it to the table. Quick question regarding the rules- depleting the deck seems like a corner case that should rarely happen, but it is not covered in the rules. Maybe a reshuffle would do?
