One of the Night-Children, made sometime in the tenth century. She won’t say what her original name was, but it sure as heck wasn’t Elsa.
Elsa is one of twins, vampires – and a most unusual heritage. She and her brother, Rai, were originally from a royal line, though bastards, and lived in Siberia, which is where Notte found them. She’s also Kin – a human whose ancestry includes some magical being – and thus, able to cast spells.
The thing is, Kin can’t be turned.
How Notte managed to successfully make Rai and Elsa into Night-Children is a mystery, even to him; only they and Jonathan, of all the Kin through history, have been successfully Made.
As a result, the heritage of Rai, Elsa, and Jonathan is highly secret.
