Something is amiss in the Emerald Dream. Immense dragons with the shimmering emerald scales of the Green Dragonflight have been sighted guarding the portals at the Great Trees... but these once-noble creatures crawl with a new, strange menace, not the peace for which
Ysera is known. Bring many allies should you dare to confront them; their powers are formidable and they will not hesitate to crush any who draw near.
