With Éothain's acceptance of Arcil's apology, they appear to have come to terms, and Arcil has decided the time has come to attack the Orcs of the White Hand.
'Since their numbers are few, I want you to sneak into the White Hand camp and defeat their leader. This should cause them to lose direction and fall into disarray.
'Go to the White Hand camp to the north-west and carry out your task, but be vigilant...it is possible that they have received reinforcements, though I think it unlikely.'
The leader of the White Hand Orcs is at the camp north-west of Aldburg.
Arcil wants you to defeat the leader of the White Hand Orcs and drive the creatures into disarray.
Arcil is in the Mead Hall of Aldburg to the south-east of the White Hand camp.
You should return to Arcil and tell him of your victory.
