Finally got around to get these into the atlas. Still not the end of my backlog, but at least a solid chunk. Thanks for the contribution.
Shame there aren't any descriptions to go with these, though I appreciate that's not an essential requirement for the Atlas. Quite a lot don't seem to have any scale or north indicator though, of which the scale issue seems more of a problem, especially for anyone who'd only be using the image versions of the maps.
The regional maps I kept the scale. But you may notice that in every section of Peredur that I have had the honor to map, there are some descriptive maps - similar to a landscape photograph/painting, these do not have scales.
I also believe it is interesting to stimulate the DM's imagination and leave him free to design/imagine a castle larger or smaller than the one shown on the map.
Anyway, thanks for the wise advice.
