Legion will initially come with two new raids: Emerald Nightmare and Suramar Palace. The former will be available soon after launch and come with 7 bosses, while the latter will follow at a later date with 10 bosses.
Created using the twisted thoughts and fears of sleeping beings’ subconscious minds, the Emerald Nightmare is a mobile area of corruption within the Emerald Dream. It travels slowly through the Dream, leaving corrupted, vicious animals and Unwaking travelers in its path.
Suramar Palace is home of the Nightborn, ancient relatives of the Night Elves and Powerful magic users. The palace is home to the Nightwell, source of the Nightborn’s magical power. Should players make it to the final boss of the raid, they will face Gul’dan.
