Biography
Mavra first encounters Harry Dresden during the events of Grave Peril at the masquerade ball held in honor of Bianca's promotion within the Red Court.

She survived, and resurfaced to Harry Dresden in Dead Beat, where she blackmailed Harry into giving her the book, the Word of Kemmler to keep Mavra from releasing photographs of Karrin Murphy shooting one of Mavra's human servants with a shotgun. When Harry handed over the book, he threatened Mavra by saying that if the photographs were ever released, he would pick up every single magic item and source of power available to him and hunt her down. Mavra has not appeared since.

Black Court Background
Following the publishing of Bram Stoker's "Dracula", suggested to be authored by the White Court as a how-to manual for exterminating Black Court vampires,  the majority of the Black Court were wiped out, resulting in the remaining vampires being only the smartest and most dangerous.
