A company of Ox-clan warriors are encamped on the western edge of the Gravenwood, arrayed for war.
'I wonder if you have the temerity to provoke the captain of these wild men? Perhaps, perhaps not.
'Prove it to me. Take this ox-skull, upon which I have engraved insulting signs, and place it before the tent of the Uch-lûth's captain. If he has any sense of honour, he will come forth and do battle with you.
'If you defeat him, perhaps the Ox-clan will return to their homes peaceably.'
The Ox-clan captain's tent may be found within Rhuvel-cadlus, in the valley below Cuthric's post.
Cuthric wants you to place a desecrated ox-skull before the tent of the Ox-clan's captain in an effort to goad him into single combat.
Cuthric is hiding on the ridge above Rhuvel-cadlus.
You should return to Cuthric and tell him that you have done as he asked.
