Forgotten Realms has always had a problem with expansion. When it first drew breath as a world for writing for Ed Greenwood, it was Faerûn and not much else. It was a tight package that more or less worked. Then they bolted on Kara-tur and Zakhara, and things got confusing, especially when Zakhara was fused into Faerûnian history as the source of both the Bedine and Calishites, and in the latter case, completely ignored the people in place. However, the recent release of Dragon Heist has changed this, by giving us a solid look at what a Tethyrian looks like. The vibe and coding for the Lands of Intrigue, Amn, Tethyr, and Calimshan, got thrown for a loop, but in a good way.
