Grimbold has sent an emissary Orthanc to demand an explanation from Saruman for his interference in matters between Rohan and Dunland. Unfortunately, there are a number of half-orcs lurking along the road to Isengard, awaiting the chance to waylay such an emissary.
'Hearken to me, ${PLAYER}. One of Théodred's men, by Grimbold's command, is on his way to parley at the gates of Isengard. It would seem that Saruman would prefer to avoid this meeting, as there is a band of particularly unsavoury half-orcs skulking along the road.
'You should clear the way for the emissary, for I would also like to hear what Saruman has to say for himself when confronted.'
