Although there are suggestions that the northern regions of Arthedain, especially that region close to Fornost, were also haunted. The Rangers went there evidently some times, but they were about the only ones. The question comes up as to why so much of Eriador is deserted, and haunting seems to be the only possible explanation given how pleasant a country the Shire is.
