Agatha Greendale told you about a grave-moss with medicinal properties that can only be found in the barrows of Haudh Iarchith, Gwantham, Goetham, and Haudh Nogbenn in the southern Barrow-downs.
'In the bowels of Haudh Iarchith, Gwantham, Goetham, and Haudh Nogbenn, there is a rare breed of grave-moss that has powerful medicinal properties.
'If you travel within those hallowed halls and are able to recover this moss, could you bring me back several samples?
'Haudh Iarchith, Gwantham, Goetham, and Haudh Nogbenn lie in the southern Barrow-downs.'
Haudh Iarchith, Gwantham, Goetham, and Haudh Nogbenn are located in the southern Barrow-downs.
Agatha Greendale has asked you to collect a rare grave-moss that can be found on several creatures that inhabit Haudh Iarchith.
Agatha Greendale can be found at the end of the Haunted Alley, near the Hunting Lodge, in Bree-town.
You should bring the grave-moss to Agatha Greendale.
