Corporal, I hate to disagree with Cadet Wakefield, but it doesn't seem like these shamans will leave so early.
I spotted several of them in the shire, so I continued to look out for anything worth notable. Still that bloody wytchery circle lays on the ground, however, more interesting is that I found a wooden box nearly the pond. It's content was a single lantern inscribed with the letters FD. I tried to take it with me, but that lantern had some abnormly weight, way over 200 stones.
However, I was not able to find any camp or like that. It seems they are sleeping under the bare moon.
My conclusion is, that this lass or lad with the initials FD is behind the showing of those shamans.
