And to show where it is in relation, the continent map. Compare in relation to this map
Mind you, the PTR is (as of the time of this post) not up but the client is available. I had to piece this file together by hand so please don't mind it being off a little.
EDIT: added a continent map to show where the plateau is in relation to the current landmass.
EDIT 2: I admit, I named the post poorly. It should've said "Sunwell Isle" instead of "Sunwell Plateau". The Plateau is the raid & Isle is the zone. Fixed.
EDIT 3: Hello, WoW Insider readers. :)
