Before the dawn of the Third Age, the kingdoms of Rhudaur, Arthedain, and Cardolan stood in opposition to one another at the cross-roads of the Lone-lands. As Rhudaur fell to vile corruption, some Men of Arthedain were held responsible for the desecration of the land and they have long waited to see a time when they could make amends for their greatest failures.
'In sorrow have we awaited this time, when the shadow would rise and our part to play be made clear... we, the cursed and forgotten, who let the land suffer while we watched. No longer shall we suffer, for the shadow tugs upon the chains about us and pulls us towards absolution. At long last, there shall be rest.
'Our brethren, long sleeping in the earth, are now taken from their slumber by fell spirits out of the past, spirits called by their master to march by his side in the fortress of Garth Agarwen.
'Now they stir where once they slumbered. West, once our home, now in ruins, the Dead walk anew. Our time is short to strike back against the past, but perhaps thou art willing to aid us?'
There are wights in the ruins west of Ost Haer.
Narthan believes that the time for absolution is close at hand and has asked you to mete justice out upon the wights infesting the ruins near Nindor and Ost Haer.
Narthan is at Ost Haer in the southern bog of the Lone-lands.
You combed through the ruins west of Ost Haer and destroyed many of the wights therein. Now you should return to Narthan.
