Manifestations of Nightmare

All around Hyjal, manifestations of corruption taking place within the Emerald Dream are appearing. The green sludges taint the land and actively threaten our way of life. We need to combat this hazard as we would demons of the Burning Legion.

Collect forty Enchanted Sludge as proof of your deeds. Do this, and I shall make sure you are rewarded well.

Be careful, these monstrosities have no value for life.

You have done well, the lands are safer thanks to your efforts. Though I still have many questions about where these creatures have come from.
