Lilith is the embodiment of excess evil that was once part of Morrigan. At the time of Morrigan's birth, this evil power was sealed by Berial to prevent Morrigan from self-destruction caused by the uncontrollable nature of her super-abundant power. After 300 years the evil power became a soul who watches over Morrigan. Jedah asked Lilith to help him with collecting all the most valuable souls by worming his thoughts into her mind. "Finally, I can have my own body!" Without hesitation, Lilith agrees to aid Jedah in his plan. [ Background Source ]
