Yay! That really helps, that does.
I have a knack for art. So if you would like, I can draw a map to scale of the aforementioned areas. I am not really familiar with these books, but as a dedicated roleplayer I am sure I can catch on very quickly. If you are interested, I can begin drawing Kharasi Weyr first. After posting the image, you can decide if you like it or not, and I can move along from there.
Feel free to draw your own renditions. I've a knack for character art but not so much for maps and scenery. I've been given more information about how Kharasi was meant to look (The Council of the original Tiazora Weyr created the idea for Kharasi and I've been trying to hold true to their vision.) So hopefully I'll get a revised image for Kharasi Weyr up eventually to give you a better idea. Otherwise, feel free to give artistic renditions of the countryside so to speak, the Holds, and maybe some of the minor offshoots of Kharasi's major holds. Just remember that they are all rather modest holds that could be compared with Half Circle Sea Hold in size and quaintness. Thyra is probably the largest and most wealthy of the holds with much more territory and even a few minor holds further out into their land.
