The Heroic Legendarium
A rules expansion for OSRIC and other compatible advanced fantasy adventure games, based on the creator’s unfinished plans for the original first-edition system. It develops incomplete concepts, adds new material, and revises existing rules in the same creative spirit. The volume presents an alternative evolutionary path for first-edition fantasy roleplaying, informed by decades of play and consultation with other fans. It is intended for groups seeking to extend the system beyond its historical form while exploring approaches distinct from later editions.
