The hobgoblin forces have not yet been found, so they must be at the very peak of the mountain. The time for battle is soon at hand.
'As we have yet to come across them in our travels up the mountainside, the hobgoblin forces can only be in one place: at the end of the Father's Path, the ruins of Uzdarulzahar at the very peak. I will return to the Thing-fold and send for our reinforcements. They will have arrived at Fellgát by now. Dréri, Náth, Molkha and Klúso will escort them. Kyrstig and I will then travel to just outside the ruins. Meet us there when you are prepared to battle Warlord Dushtalbúk!'
