Moonfire

A d20 System campaign booster that expands an existing swords-and-sorcery campaign without requiring a new setting or a fresh start. It introduces new twists to familiar rules and provides a cosmological framework to explain changes between the campaign world and the mundane world. Gamemasters can use it to refresh established locations, cultures, NPCs, stories, and player characters while maintaining campaign continuity. The additions alter how the game is played without burying the campaign in extensive new rules.
