Rovalang beheld a frightening meeting atop the Hill of Erech, and does not know what it signifies, but you know part of its significance, at the least: Aragorn spoke with the oath-breakers in the dead of night.
'I know little of the Dead, and count myself lucky. Who can say what drove them to meet with that curious company and its grim-faced leader?
'You know of this man. I can see it in your face. Are you willing to speak of him?'
Rovalang stands on the slope of the Hill of Erech.
Rovalang wishes to learn more of the meeting between the Dead and Aragorn, if you are willing to speak to him.
