Arry - I really like your ending post. It's likely what would have happened!
My preference is that most of the people in Wulfham survive the journey and make it to Edoras and then on to a place of safety. (Of course, a few would likely have been killed on the road due to hardships, and there might have been some "close escapes".) If Arry or someone else prefers a different ending, I would request that Dorran's sister Creide not die because I may use her in another RPG. After the war, I think some Wulfhamites realistically would go back to restart the village, while others would venture elsewhere (kind of like what is happening with New Orleans).
I prefer to do personal epilogs for my characters, but I'd have no trouble weaving this history into Dorran's post (in 2-3 sentences) if that is needed. I am thinking of taking Dorran about 10 years ahead. Dorran will likely join the Riders and, shortly after the war, end up as part of Eomer's household.
Leod will become a "teacher of healers". He will start that even in the refuge to which they are fleeing. (It is a bit much for the poor fellow to go out with the Riders.) If any of your characters are interested in getting training as a healer, you are welcome to mention in your post that you received such training from Leod

.
I still have one or two things I need to coordinate with another poster, and I am working on that. Then I'll put up my epilog.
