The Stone That Started A Revolution

Objectives
Crusade Architect Silas at the Valley of Echoes in Icecrown wants you to retrieve 10 Trunks of Crystalline Heartwood and 10 pieces of Ancient Elven Masonry.
 * Crystalline Heartwood (10)
 * Ancient Elven Masonry (10)

Description
You may look at Scourgeholme now and see a rancid pit of decay, but one day it will be a place of glory and honor. Highlord Fordring has deemed it "Justice Keep."

Alas, even an impregnable fortress like Icecrown Citadel began with but a single stone. So begins our search for the stone to start a revolution.

Travel to Crystalsong, south of here, and seek out the Unbound Thicket in the east. Once there gather crystalline heartwood from the thicket floor and elven masonry from the Ruins of Shandaral.

Rewards
You will be able to choose one of these rewards:

Progress
Are you lost?

Completion
Heartwood by nature is resistant to disease, rot and plague. This heartwood, goes so far as to repel such things! The masonry, affected by the fallout of the Unbound Thicket, will work in much the same way.

Soon we will break ground.
