Attack From the Underdark

The evil Drow are starting another attack on the surface with the aid of a beholder, but our heroes are fighting it back. I grew up playing forgotten reals, reading the stories of Drizzt Do'Urden, so the Drow and their malefactions are essential to me when thinking about D&D. I would have loved to build an Elminster in the heroes' party, but unfortunately, you can't get hold of a red wizard's hat.
