The dwarves have devised a plan to convince Mazog the Ghâsh-hai are marching against him.
Objectives
Defeat Rûgh
Light the banner on fire
Rûgh can be found at Uzbad-bakân, north of Anazârmekhem and beyond the bonfires.
Gapi wants you to defeat one of Mazog's leaders at Uzbad-bakân and then set his banner on fire. He believes this will convince Mazog that the Ghâsh-hai are on the march against him.
Notes
Rugh and the Banner are in a very small camp up three to four levels from Anazârmekhem. Go up the steep stairs from Anazârmekhem, then north to the next west bridge, then west, then north and just keep taking every up stairs along the way.
