Certainly. Under Shadowdale and immediately NW is an underground lake and extensive caverns, and there are also Underdark drow settlements under Sembia itself.#Realmslore

No, very few drow near Sembia venerate the Dark Dancer (or Vhaeraun); the vast majority worship Lolth.
There are relatively-nearby Eilstraee-worshipping drow to the west, in Cormyr; to the south, near Starmantle; to the northwest, W of Daggerdale; and in the Vast.#Realmslore— Ed Greenwood (@TheEdVerse) August 2, 2020
