Skies Over Cormyr
The Moon Sea. Officially the location of a number of independent city-states, unofficially the worst kept secret on Faerun. Centuries ago they were demolished by the Netheril when they began re-establishing their empire, once thought defeated as Shadovar troops captured city after town.
The abrupt disappearance of the Shadovar and their re-born Empire of Netheril allowed the Zhentarim to flourish, and flourish they did. Now Zhent in all but name, the cities of the Moon Sea are ruled by mercantile councils, their efforts turned towards economic, not militaristic, conquest.
