Diane (Fallout: New Vegas)

 is Great Khan living in the Mojave Wasteland in 2281.

Background
Diane and Jack are advisors to Papa Khan. The pair run a drug trafficking ring and supply the Great Khans with drugs as well. It is implied that they have an emotional attachment to each other, or at least Jack does since he becomes upset when told that the Legion would put Diane into slavery. As a side note if you can pass a 50 Barter check, you can convince Diane that it would make sense to try to sell more helpful chems to the surrounding settlements, with a success she will agree and you will get 50 exp and a nice Karma boost. Alternately, you can achieve the same with Jack via a Speech check.
