Eberron is a campaign setting for the Dungeons & Dragons role-playing game, known for its unique blend of magic and technology. It features a world where magic is integrated into everyday life, powering airships, magical trains, and even cities. The setting is rich with diverse cultures, including the Warforged, a race of living constructs, and the Dragonmarked Houses, powerful families that wield magical abilities tied to their bloodlines. The history of Eberron is shaped by the Last War, a devastating conflict that ended with the signing of the Treaty of Thronehold. This treaty established the nation of Breland and other independent states, while the remnants of the war continue to influence politics and society. Eberron is also home to ancient mysteries, powerful artifacts, and the enigmatic Mournland, a desolate area that holds secrets of the past.
