Radagast could smell death, as if from an ancient grave, on the moss. He believes that it is mostly likely wights and wishes me to travel to Haragmar and slay them.
I threaded through the swamp and came upon this evil place.
I found plenty of wights and managed to kill about 15 of them. Once I returned to Radagast, he explained that my efforts would be of much help in the days to come.
