There are two small encampments that the Draig-lûth established. These men are dangerous and prey upon the Uch-lûth.
'Duvodiad, your aid is welcome. Continue, if you would, to harry the sentries of the Draig-lûth at Pruv Cadlus and Sarf Cadlus. If you do this, my people will keep you in esteem.'
The Draig-lûth camps are east and north-east of Harndirion.
Gronu has asked you to seek out Pruv Cadlus and Sarf Cadlus on the eastern slope below Harndirion and defeat sentries at each of the camps.
Gronu's camp lies almost due north of Harndirion.
You should return to Gronu and let him know that you have defeated many of the sentries near Pruv Cadlus and Sarf Cadlus.
