Supposedly there is a Dark Justiciar helm in the blighted village on a skeleton that also makes Shadowheart react. I haven't been able to find it, but I have seen a few mention it. This is not the scene behind the windmill. It's another one.
You can find it by entering the Blighted Village from the entrance facing the direction of the Grove and going right between the building and village wall until you reach the end of the buildings. The corpse should be next to the last building there. The shape match the representation of the defeated Shar followers on the Grove's mural.
