You have done all you can in the western part of the Isendale, and now it is time to move on.
'You have done all you can here, ${PLAYER}. It is time to move on.
'Travel south until you reach the Isen, then head eastward along the shore until you find a large rock outcropping. There, you will find another of our scouts, Innoth.
'I am certain that Innoth will have as much need of your aid as I.'
Innoth can be found by travelling south until you reach the Isen, then east along the shore until you reach the rocky outcropping where Innoth is encamped.
Garrun has sent you on to speak with Innoth near the river Isen.
