Named for the grandmother of Eleanor of Aquitaine and born the daughter of a French actress and a French nobleman, Dangereuse St. Richard grew up on the stage. She loved her life and her parents until the French Revolution tore her world apart. Caught between the two warring factions, she refused to see the noble half of her family killed. Using her connections in the theater, she tried to smuggle her father and noble half-siblings to England. Her husband was the one who betrayed her into the hands of the Committee. She was killed trying to protect her small brother and sister from the guillotine.

When Alexion was sent to judge the Dark-Hunters of northern Mississippi, he stayed with Danger, was surprised at how short and petite she was as Artemis doesn't make short Dark Hunter's, and fell in love with her. They were attacked by Daimons and Stryker stabbed her in the heart with a knife. She would have existed after death as a Shade if Acheron hadn't allowed her to live in Katoteros.
