Mafia 87. At the Dawn of War

The query "Black Beatrix" definitely leads to Uma Thurman. From Wikipedia: "The quirky name, meaning 'bestowing bliss,' was given to Uma by her father, Robert Thurman – a remarkable personality in every respect. He is generally considered to be the first American in history to be ordained as a Buddhist monk personally by the Dalai Lama."

"Dalai" means "ocean" in Mongolian, in the sense of "Great" (ruling khans after Genghis Khan bore the title of Dalai Khan), and "lama" (bla ma) in Tibetan is equivalent to the Sanskrit word "guru" and means "teacher."
