Ingold worries that Easterling raiding parties coming out of Talath Úrui may discover Gondor's presence in Dor Amarth and focus their raids on this outpost.
'${PLAYER}, have you seen the Easterling raiding parties that come from the south? When first they set foot into Dor Amarth, they simply were content with hunting game. Now they are more emboldened and look to pillage. We should send these men back to the south before they strike up the courage to plunder our small outpost here on the plain.'
Easterling raiding parties can be found in western Dor Amarth.
You should defeat any Easterling raiding parties you come across.
Ingold can be found in the Ruins of Díngarth.
You should speak with Ingold.
