Passau is a persistent fantasy world simulation where players create and rule their own realms on a shared physical map. Manage population, armies, gold, and food while expanding your borders across a living world.

Every decision shapes the map itself. Cities grow, territories change hands, alliances form, and wars reshape the landscape. Players can track the world visually as kingdoms rise and fall, with the map updated regularly to reflect the outcomes of diplomacy, strategy, and conflict.
