Peacekeeper  

This quest is triggered by examining "a discarded hammerhead".

1. Harvest 20 wood from corrupted arbors
1. I should kill the root horrors that lurk within the charred forest to find some golden leaf.
• a bramble beast and a withered bramble give the update
• I found these at (-298, 10, 310) & (-410, -0, 237). Most of these in the area are heroic, but if you look around you can find non-heroic ones.
2. I need to kill the Oak Matriarch to find a magical etching tool.
• The 6 oak maidens are her placeholder.

The quest completes as soon as you kill the Matriarch.
