I was curious have you tried adding more towns, villages, and castles to fill in the empty places in the map. Maybe even try and add another faction or two. Cause you do have those big islands in the middle of the lake between the western empire, southern empire and the Aserai. Maybe a long forgotten city and you can do a quest or just a single town. Or even add something in thats like the vikings or other raiding like faction on those small islands to the west. Even if it's in future DLC after the game leaves development stage. I'd love to the see the map filled up rather have a lot of empty space.
