Devlog: World Structure & Next Steps

I've been working on improving the overall world generation. I'm quite happy with the way the walled cities started to pop up :D. 
Next comes roads, underground levels, caves systems crossing mountains connecting different zones and 3D walkable buildings... that seems like the least ammount of level design I must do before going into narrative work... I'm actually both eager and afraid of going into narrative design, that's a new thing for me and I have no idea how to approach it!!!!
