A project I'm working on.
I made a swamp in World painter that I'm filling with ruins.

In the center of the map there is a small island in a lake.
On the center island there is a ruin with bridges pointing out south, east, west and north.
The bridges are leading to different ruin towers and houses.
There are three towers, one cathedral, a small house and fishing/boat house.

I'll upload the save file when I'm done and that can take a while.
