I think it'd be fun to have the ability to use your True-Soul Status to get them to betray their leader and join you instead. And then order them to do 'Insert action here.'. Maybe even make them do good deeds like protect people. Or Pillage and Steal in your name. Like there's plenty of choices.
That'd be neat. It should probably be a hard check and have some consequences when you come face-to-face with Minthara/Ragzlin/Gut. Oh and being a Drow could give you some kind of bonus to the check.
