Svanr wishes to travel eastward through Nud-melek once more.
'I am ready to leave and head eastward, ${PLAYER}. Will you escort me on my journey? With the bridge gone, I fear the way might be dangerous.'
The summoning horn can be found near the Bridge of Khazad-dûm, behind Svanr in Nud-melek.
You should summon Svanr to your side when you are ready to leave.
A good place to rest can likely be found near Sudulthurkh, the northern cross-roads of Nud-melek. Svanr can be summoned using the horn he gave you.
You should make your way east across Nud-melek by heading north of the great chasm.
Svanr is at the cross-roads of Sudulthurkh in north-eastern Nud-melek.
You should speak with Svanr.
