Thanks ravells.

As this belongs to the Points of Light concept of assumed 4th Ed. setting, I tried thinking what the folks would do. Partly this was the clustering around in a tighter region, the farm not far off (the wavy lines in the south are the outlying fields) and building close to the keep, but not too close.
I also added the old tower who serves as quarry sometimes to show that ohter structures stood before the world fell into darkness again.
I hope to upload a new version by tonight.
