lore wise pretty major things happened in the lady penitent series.
Eilistraee absorbed Vhaeraun and got a bit darker whilst attempting to outmaneuver her mother for the souls of the drow that were not necessarily evil.
Eventually the gambit failed and the chosen of Eilistraee and Eilistraee herself both died.
However Corellon then appeared at the very same chess table and won on his daughters behalf, allowing her wish and removing the curse from those drow, they stopped having the black skin and white hair and instead simply had dark skin and dark hair like the original Ilythiir had had.
Of course after the events of the spellplague and the second sundering, many gods, including Eilistraee and Vhaeraun came back.
IMO the "Seldarine drow" should have been simply called dark elves, because the original drow before they became drow were still even then, called dark elves.
Lolthian drow should lose the "lolth" part in their name and just be drow. Because drow follow other drow gods than just Lolth, Selvetarm, Vhaeraun, Ghaunadaur... Kiaransalee etc.
