A multiplayer mod for Mount & Blade II: Bannerlord that puts multiple players into the same campaign world. A dedicated server runs the full campaign simulation — all 1100+ lord parties, 493 settlements, economy, politics, and wars. Players connect and see each other on the map in real time. Fight together, or against each other. Server-authoritative architecture means one source of truth for everyone.
