The stranger that summoned you was a kinsman of Amdir who is seeking the missing Ranger.
'Thank you for your aid, ${PLAYER}. My kindred and I were driven from the Bounds of the Shire by the Nazgûl of Mordor. They pursued us eastward and slew many of us. It was my goal to join Amdir, but I have heard rumour of his fate in Archet. They say he was stabbed with a morgul-knife and led off by some evil Men -- the ones who lent the Blackwolds aid. There are few left now with power over such wounds, and those that I know of dwell some distance from here. We must find Amdir, and quickly, if we are to save him.
'He is likely being held by the Blackwolds somewhere in the Chetwood. We must find a way to enter their lair and free him, but first we must find them. Speak with Constable Underhill... he may be of help. You can usually find him outside, near The Comb and Wattle.
'Once you have learned of the Blackwolds' lair and believe you can gain entry, return to me. Hurry, before it is too late.'
Constable Underhill can be found outside The Comb and Wattle Inn in Combe.
Toradan has asked you to speak with Constable Underhill to learn ways of finding the Blackwolds' hideout. He is certain Amdir will be found among them.
Many of the scattered Blackwolds dwell in the hills east of Combe.
Following Toradan's advice, you spoke with Constable Underhill about the Blackwold brigands. The hobbit constable suggests that you search amongst the camp-fires of the Blackwolds to the east of Combe for one of the brigand agent's letters.
Constable Underhill awaits your return near Combe centre, outside The Comb and Wattle Inn.
Searching through a pack found near a small encampment of Blackwolds, you found a letter from the Blackwold agent. You should return to Constable Underhill with the letter.
