Madame Estella Lempoure is a woman who was a snake in life and death, leeching from those around her to get what she wants. She's cold, and doesn't respect anyone but herself. But one fateful night, she is killed for her greed, shot dead by someone she took advantage of in the past. She obviously went to hell for her sins, but Satan admires her work, so he struck a deal with her. She could roam the earth again, to leech from others, not just their wealth anymore, but their life force as a whole.
