Astarion had known the woman's face immediately - Thalia Dhune, the golden daughter of Baldur's Gate. The princess of the upper city. How many times had Cazador sent him after her - wanting to claim the socialite as a trophy to add to his awful collection? At least now he wouldn't have to go back to his master empty handed, should the tadpole situation not work out in his favor.
(or: what if the Dark Urge was a noble woman, perfect and popular, and her father's favorite fox in the henhouse. and of course, what if our dear vampire knew of her before the crash?)
