This is true. On the other hand it also seems that:Zeromaru X wrote:The Scales of War adventure path starts in the Elsir Vale, that was part of the Nerath empire, and then you can explore the rest of the Nerath world and outer planes.
1. There is no official placement of the Elsir Vale in the Nerath Setting (map).
2. The Elsir Vale debuted in Red Hand of Doom which predates 4E and the Nentir Vale/Nerath Setting.
3. The map of the Elsir Vale is actually a copy of the Shar region from the Forgotten Realms:

To me it seems that the Elsir Vale falls into the same category as the Keep on the Borderlands, Tomb of Horrors, The Lost Caverns of Tsojcanth, White Plume Mountain etc: That is, while they exist in the Nentir Vale/Nerath Setting, they do not belong exclusively to the Nentir Vale Setting.
When this thread was started, Knightfall asked if the Elsir Vale could be incorporated into the Nentir Vale Setting and I think this should be fairly easy given that there is already a precedence for this in the Scales of War Adventure Path as you point out.
