Find the Caravan Chest in the Fallow Sanctuary, obtain the Wizards' Reagents and bring to Watcher Biggs.
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, [player]. Get them and bring them to me.
