Alright so here's the jest, no story line just down to the map. This is a regular kingmaker map, I didn't put a whole lot of work into it. I've played it a couple times so far.
The idea is simple. There is a mountain estate that you will either invade and conquer or defend and destroy your enemies.
The map features five castle estates and four villages. The castle estates are in the corners and the estates are in between the castle estates.
I have the Updated AI castle thing from this site which makes the Queen a royal pain, constantly sending hordes of swords men. If you like a challenge, play on a lower estate and select all enemies to be the queen. You will have your hands full for a little while. Once you gain force you can start taking the villages next to you before taking on the ground level castles. Then, there's only one way to go. UP! The mountain that is.
If you're bored of the default maps, or if you've played half the kingmaker maps on this site. Give this map a shot. It'll atleast provide for some fun.
