Otto Von Drak's daughter Isabella was noble, vain, and unremarkable. When Vlad Von Carstein seized Sylvania after her father's death and married her, what began as a political arrangement became something far more formidable. Isabella grew devoted to Vlad absolutely, and he came to depend on her completely. When illness began to claim her, he granted her the Blood Kiss rather than lose her. Now an independent power in her own right, Isabella carries the Blood Chalice of Bathori and fights on the front lines — and when she and Vlad share a battlefield, both of them fight better for the other's presence.
