What is migration?
Character migration can only occur once InnoGames establishes a migration route from a character's current world to any other world(s). Character migration is optional in the beginning, however worlds allowing departure will likely be scheduled for closing once enough players have left; and after this point, the migration will be inevitable. Please note these processes are defined by InnoGames, considering many essential factors.
Character migration ensures each running world contains enough players to maintain a competitive nature. Without the necessary participation, key factors of the game become impossible; notably fort battles and dueling both require player versus player interaction that becomes increasingly difficult with fewer players.
