Retrieve the contents of one of the Dalaran wizards' crates. You will find Pyrewood Village to the south.
As you may know, the town of Ambermill remains a source of human opposition, mainly through the support they receive from the wizards of Dalaran.
I don't know what their plan is, but for them to show interest in a backwater village like Ambermill indicates that it must have some greater importance.
They've been shipping crates by the wagon from Hillsbrad. Many of those supplies end up at a small camp north of Pyrewood Village. Retrieve the contents of a crate and return them to me.
