Many years ago, Shakira kidnapped Athlstan's pregnant wife, Kestri. A rescue attempt led by Xenograg the Sorcerer failed. Kestri's mutilated body was found some weeks later. There was no sign of the unborn child, dead or alive.
The child, a girl, was alive. Shakira named her Lily and raised her as a daughter. Thus a human was raised from birth by a demon. Lily in fact believed Shakira to be her true mother, and Shakira's hellish realm to be her proper home.
