In your quest to defeat Cazador, you stumble upon a pale elf begging for your help. Oddly she is not charmed like the others. After questioning her you find that her brooch is behind her breaking his charm spell. A brooch like that is something that could be handy in your quest to defeat Cazador but she begs "let there be anything else, this brooch is a family heirloom and my only guarantee to safety" You also discover she is one of Cazador's sex slaves, so maybe she can offer you one of her services in exchange for her freedom?
