Lily was embraced by 13th generation german vampire of unknown clan named Rolf Toten. Rolf explained very little to his childe, other than that Rolf's group couldn't take her in because she would be a liability as one of the Thin-blooded. Lily sired another thin-blooded called E, who rejected her once he found out what she had done to him.
After the incident, Lily refused to drink blood from the living. When she grew hungry, however, she broke into the Blood Bank, without knowing it was run by none other than Vandal Cleaver - Therese Voerman's ghoul. He kidnapped her and kept her as a "donor", draining her for blood and selling it on Therese's behalf to the kindred population of the Los Angeles area.
