saveliev87, you probably captured the castle that was part of the quest. The quest is completed. There is no quest to capture all the castles in this mission. You only need to reach the port. The game version has nothing to do with it. I heard that if you don't kill the dragons, you get experience. But I also killed them. So I don't know what gives more experience. Anyway, Agrael reached level 30. I first captured the elven cities, and then my own. I didn't go to the target castle until I maxed out Agrael. There are still many neutral creatures left, including phoenixes.
