Shapur

Shapur is a female drow who has been sent to lead a party of drow and driders to hunt down two rebellious drow teens, Kaelet and Umar, who have dared to try and escape from drow society in the Underdark. During the events of Baldur's Gate: Siege of Dragonspear, Gorion's Ward can encounter her in an optional portion of the Underground River, where she is in the middle of a stand-off with a Shining Crusade patrol led by Therli. If the party tries to seek a diplomatic solution, she gives out the quest Drow Runaways, but it is hard to not end up in battle with her.
She has unique dialogue if the party includes Viconia DeVir or Baeloth Barrityl when they first meet her.
