Stalling the Ravage

Objectives
Slay 12 Kunzen Hozen.
 * Kunzen hozen slain x12

Description
The Kunzen hozen, up in the mountains to the west, have been acting up, lighting their fires and shouting their chants. Based on what I've heard and seen around here, that means that a ravage is coming.

There's not much we can do to stop the ravage, but we can at least thin their numbers before they attack.

Rewards
You will receive:

Progress
The ravage could come any time now. We have to be prepared.

Completion
They'll be attacking, but my farm - and the farms of my friends - should not be in any danger.

Not if we can help it, anyways. Right, ?
