The Emerald Nightmare (or the Nightmare for short) is a mobile area of corruption within the Emerald Dream. Despite the defeat of Xavius and the removal of much of the nightmare through the course of the events described in Stormrage, players will get to experience the Nightmare in Val'sharah with the release of the expansion Legion.
Nature of the Nightmare Edit
The Emerald Dream is not a place of total perfection. It can be shaped and twisted by dreams, usually without a sleeper’s knowledge. Sadly, nightmares are themselves a crafting of the subconscious and have given rise to their own place within the Dream. The Nightmare, as the denizens call it, is not a specific location, but a constantly roaming effect that travels about unpredictably.
The skies above the Nightmare are constantly clouded, creating a gloomy, depressing zone that weakens and deadens everything it touches. The beautiful green vegetation is twisted into brown decay, while ordinarily peaceful creatures are corrupted into shadowy, mutated versions of themselves known as Corrupted Ones. The Corrupted Ones are vicious and cruel, hunting anything they can, even after they leave the Nightmare’s affected zone.
Worse still, some dream-travelers who enter the Nightmare — or are engulfed by its movements — become trapped in the Emerald Dream. They cannot leave, so their bodies back on Azeroth remain in a permanent sleep, slowly starving to death unless tended by helpful aides. While trapped, they are known as the Unwaking; they are also corrupted, and will do anything to get back home. The Nightmare is believed to be slowly growing in size and power. ( )
The reasons why the nightmare has become so strong in recent years was long unknown.
Although Xavius did not create the Nightmare, he came to rule over it as the Nightmare Lord. Xavius orchestrated the corruption of the Emerald Dream by manipulating Fandral Staghelm into planting a branch of Xavius's own tree into Teldrassil, ensuring that the new world tree would be corrupted from the start. His plans culminated in a daring attempt to bind Azeroth and the Emerald Dream into one plane, seizing control of Azeroth's residents while they slept and giving shape to their nightmares. Xavius himself was a minion of a powerful yet ancient evil (confirmed to be N'zoth). Despite Xavius' defeat at the hands of Malfurion Stormrage and his allies, the Nightmare was not entirely destroyed following its master's defeat.
One small part subbornly stayed in the Rift of Aln, and Malfurion could only seal off the vicinity around the rift until a time that another war would be in their favor. The Nightmare's influence in the Barrens following the Cataclysm suggests that the evil controling the Nightmare may have taken advantage of the event to attempt to infect Azeroth once again.
Many druids are called to the Emerald Dream to help fight back its effects. So far, the green dragons have done what they can, though they dare not risk becoming themselves corrupted. The Eye of Ysera has not yet been approached by the Nightmare, but some fear that one day it will. (+ )
In World of Warcraft EditThis section concerns content exclusive to World of Warcraft.
The Nightmare is created using the twisted thoughts and fears of sleeping beings’ subconscious minds to corrupt the Emerald Dream. It travels slowly through the Dream, leaving corrupted, vicious animals and Unwaking travelers in its path. The Night Elf druid Naralex and his former acolytes in the Wailing Caverns have been corrupted by the Nightmare - transformed into the wicked Druids of the Fang. Eranikus was corrupted by the Nightmare.
Even Ysera's most trusted lieutenants (Lethon, Emeriss, Taerar. and Ysondre) have been warped by this dark power within the Emerald Dream. Malfurion fights at Cenarius' side against the Nightmare within the dream, but may have been turned into an Unwaking himself.

The Nightmare seems to have found a way into one of the wings of the Stormrage Barrow Dens where strange creatures of nightmare suddenly come in to the waking world. The Cenarion Dreamwarden are constantly trying to keep the threat at bay. Plant life is thriving here, but this is not the case in the Emerald Dream. Clintar Dreamwalker can be found asleep in one of the rooms and he is part of the quest chain for Swift Flight Form. It seems Anzu is behind these attacks.
