Ivy

Ivy, usually known as the Archive, is a human girl and holder of the Archive.

Biography
Ivy was born to a long line of women holding the Archive and passing it from mother to daughter. Her grandmother was killed young; Ivy's mother, still young, could not handle her new role and killed herself, thereby passing the Archive on to Ivy.

As she has no name other than "The Archive", Harry Dresden nicknamed her "Ivy".
