Speak with Watchmaster Sorigal.
Our mages are conducting research at Nethergarde Keep in the Blasted Lands, research vital to our understanding of the Dark Portals. They require nearly constant supplies, but our supply line to Nethergarde is tenuous.
You must help ensure the supplies make it to Nethergard. Report to Watchmaster Sorigal in Darkshire, and do as he asks. This task will take you into hostile lands, [player]. Prepare yourself.
