A campaign setting is a fictional world or environment where a role-playing game (RPG) takes place. It provides the backdrop for the story, including its geography, cultures, and history. Popular examples of campaign settings include Forgotten Realms and Eberron, which offer unique elements that shape the adventures players experience. In a campaign setting, players create characters that interact with the world and its inhabitants. The setting influences the rules, themes, and challenges faced during gameplay. Game masters use the campaign setting to craft narratives, quests, and conflicts, making it essential for immersive storytelling in RPGs.
