I was stunned during the attack by the Lost Ones, but before my sight went black I spied one of our wagons being dragged to the Fallow Sanctuary, the lost one village to the north.
A caravan chest with valuable reagents was in that wagon, reagents vital to the studies of the wizards of Nethergarde Keep. Find the chest and get those reagents, <name>. Get them and bring them to me.
Ah, you found them! With these, the wizards in Nethergarde may continue their work. I do not know what it is that they do, but it is linked to the Dark Portal in the Blasted Lands, and is vital to the security of the Alliance.
