Neverwinter in terms of iconography and fictional history. Neverwinter is the kind of city that you name a game after, in fact. Possibly even two games if you want to get technical about it.
Perfect World's latest website update pays tribute to the town known as the Jewel of the North with a bit of expository text to bring you up to speed on Neverwinter's place in the D&D timeline. The firm has also released an accompanying video that you watch after the break.
