Unlike a home campaign, Dave Arneson’s Blackmoor: The MMRPG is designed to allow you play in episodes at a number of conventions, gamedays, retail outlets or home games. The campaign uses the concept of episodes to represent a single chapter in the ongoing story of the campaign. You can adventure with your character from episode to episode experiencing the rich world that comprises Dave Arneson’s Blackmoor. As you complete each episode, your character will grow and change as you amass experience, fame and glory in each episode you play.
