Ivorel feels personally responsible for poor Hal Tiller, a young hobbit that accompanied her scout expedition.
'I must not give up all hope for poor Hal, though in a place as cruel as this I dare not hold too much....
'We must hunt down the black dogs that cornered him and see if we can find any clues to confirm his downfall... or perhaps a body so that we might at least put him to rest, though the Black Dogs are rarely so considerate as to leave much behind.'
Black dogs can be found throughout the Scuttledells.
Ivorel has asked you to hunt down black dogs in the hopes of finding some clue -- or perhaps the remains -- of Hal Tiller.
Ivorel is at her camp in the Scuttledells.
You should return to Ivorel and show her the remains that you have collected.
