The local militia is hunting down a renamed bandit chief down to it's swamp fort.
I wanted to make a wood castle, but every time I made one, it looked out of place. But for a bandit camp in a swamp, the wood castle felt right into place.
I have provided no siege engines to the attacking force becouse it makes it too easy, and it's unlikely you where going to see suppky wagons on the swamp bringing in materials for the siege engeneers to build them. But if you want, you can, there is a small clean space near the front of the castle where you can build your siege equipment.
