The Orc-scouts ranging out from Taur Morvith act as the eyes for their gathering forces.
'Greetings, ${PLAYER}. Do you see those camps down there? You can faintly make them out through the shrouding mists, but they are there, and they are looking for us as well.
'Orc-scouts range throughout Taur Morvith, trying to find us and entrap us so that their larger forces at those encampments can come down upon us with superior numbers. That, we cannot allow!
'I need you to hunt down the scouts...and while you are doing so, attempt to intercept any of the messages they have been trying to get through to Gathbúrz.'
Orc-scouts can be found throughout Taur Morvith.
Iavassúl asked you to defeat the Orc-scouts ranging outside of the forts in Taur Morvith and to intercept any messages they might be trying to carry through to Gathbúrz.
Iavassúl is at Iavassúl's Watch in Taur Morvith.
You should bring the message you intercepted to Iavassúl.
