Eleri has a more dangerous request for you now, but if Tharbad serves as a camp for the Uruks that raided Mossward, she wants to know about it.
'I have one more request of you, ${PLAYER}, and then I will be satisfied. This may be more dangerous than your earlier scouts, and if you hesitate to accept this task I will understand.
'The old city of Tharbad is to the north-west of Mossward. It has not been the thriving centre of trade it was during the height of earlier kingdoms for hundreds of years, and it has been abandoned ever since flood-waters took the last of its great bridges....'
Eleri raises an eyebrow.
'Abandoned by good folk, ${PLAYER}. Has it become a den of Uruks? Is that from where Madthrug's raiding band came? This, then, is my dangerous request. I ask that you go to the gates of Tharbad and look for some sign of the insignia he wore: the mark of the White Hand. Beware, for if Tharbad is truly held by forces of evil, you may be better served by keeping from their notice and not engaging in battle.
'Tharbad is to the north-west of Mossward. Go just to the gate, mind you, and no further.'
Eleri asked you to look for the mark of the White Hand at the gates of Tharbad, north-west of Mossward. She was very insistent that you avoid battle if the foes there seem too dangerous.
