As a DM, I've dealt with the historically problematic nature of drow in D&D (and to an extent in Eberron) by going full Black Panther: the drow nations in Xen'drik, like Wakanda, are secretive, but maintain magics and technologies unavailable on Khorvaire. They focus all of their time and energy not on worldly concerns or geopolitics, but on defeating threats from Khyber (that last part is partly canon.)

As my players get into 2nd and 3rd tier in Xen'drik on unrelated quests, this is a cool reveal; I also have players get into geopolitics at this tier to balance against their power as PCs.

I also liked Exploring Eberron and nations beneath the waves like the Valraen Protectorate, and wanted to extend this idea further: there are political players, and nations, that can world awesome power but that nobody knows exist...
