Narmeleth believes that baring the shattered hilt of Dúnachar before Mordirith will weaken the False King's will.
Golodir listens to your account of Narmeleth's plan, and nods.
'I took the broken hilt of Dúnachar with me when I buried my dear Lorniel, and by her grave it lies still. After her death we carried her as far as we dared under the cover of darkness; she rests atop a hill on the northern slopes of Gorothlad.
'If the blade of Dúnachar will aid you in your fight against Mordirith, I give you my leave to retrieve it.'
Lorniel's grave is on the northern slopes of Gorothlad, south of Nan Gurth in Angmar.
Golodir has given you the location of Dúnachar and has given you permission to retrieve it.
Golodir is at Gath Forthnír in the northern reaches of Angmar.
You should return to Golodir with the broken hilt of Dúnachar.
