Amarion has asked you to offer assistance and company to Orthonn, a Ranger tasked with manning a lonely post in the wilds of Annúndir.
'What a help you have been to us, ${PLAYER}! I imagine that with the Wargs driven off, we can put this area back to right.
'I must ask one last thing of you. My friend, Orthonn, watches over Annúndir from a lonely post. Very few folk come his way. Would you check to make sure that he fares well, and offer him news of the western Downs while you are there?'
Orthonn can be found at his encampment just over the river in Annúndir, not far from the road.
You should find and speak with Orthonn.
