Catalina's parents were Carpathian warriors, members of the powerful Dark Blood lineage. They were killed by a Sange rau and their daughter Catalina was discovered in the aftermath by Lycans who assumed she was one of them and raised her as such. Catalina married a Lycan named Hemming and their daughter was Aubrey. Since Catalina was originally Carpathian and shared blood with her Lycan husband, she eventually became mixed blood (Hän ku pesäk kaikak). When she began to have visions of something worse than vampires, she seeks an audience with the Carpathian prince, Vladimir Dubrinsky, to save both of their species. However, her secret was found out and, fearing she would bring them death, she was murdered by their pack.
