The Emerald Nightmare: Piercing the Veil

Objectives
Collect 4 Essences of Clarity from Cenarius in The Emerald Nightmare on  difficulty.
 * Essence of Clarity (4)

Description
The darkness of the Nightmare is like a heavy shroud, warping reality and altering the perception of all living things. As areas of the Dream are cleansed, Xavius's hold weakens, and the way to the heart of the Nightmare will be revealed. But there might be a more direct way... my teacher once spoke of a pure power that could illuminate the darkness of the Nightmare, and allow all paths to become clear. But alas, Cenarius is lost....

Rewards
You will learn: Waking Dream (buff)

You will also receive:

Progress
If only Cenarius were with us, we could confront Xavius at once.

Completion
Incredible... where did you find these? With these Essences, I will be able to open the way directly to the heart of the Nightmare. Let us make haste!
