Gaming is fun, and fun is for everyone
Maybe a sourcebook/adventure set in the plane-spanning Illithid Empire before the Gith uprising? Or perhaps set in the Court of the Githyanki Lich Queen Vlaakith.
An Empire of the Spider Throne adventure during the rule of Vecna and Kas would be fun as well.
Damn I'd love either of these so much. Although it's hard for me to imagine either as a "wonderful" place. But maybe that line is just hyperbole?
