Callisti y Castillo
Rafael de Corazon (1182 AD)
Prince of Buenos Aires
Some older Toreador claim that the real name of Callisti y Castillo is actually Alexandria, who is believed to be a Fifth-Generation Toreador that controls a number of casinos in Chile and Argentina - an extremelly beautiful vampire who is responsible for most of the Camarilla's activities in Argentina.
She travelled to the New World with Francisco Pizarro's expedition. She is known to have feuded with Helena, another ancient Toreador who came to the New World around the same time.
She is the current Prince of Buenos Aires but not your typical Toreador. In addition to her already busy schedule, she is possibly the greatest art thief to ever exist. She has stolen many of the greatest masterpieces in existence, replacing them with undetectable fakes.
Other Princes have placed her on their most-wanted lists under the identity of "Red Ludwig". She is the owner of one of the largest private collections of museum-quality works.
