Bio: Ana was a member of a research facility run by Persephone and Soteira. She and her son were murdered by another member of Soteira doing Persephone's dirty work, Zagreus. Persephone, whose mutant power is to control the dead to such an accurate degree that they can fool Wolverine's senses, then resurrected Ana (she only believes that to be the woman's name) and used her to lead a very recently returned from the dead and very confused Wolverine down a very specific path she had planned for him in hopes that she could once again take control of Wolverine, like she had when he was dead.
Eventually, through Ana, Persephone revealed herself and let the woman "stay dead". Although with Persephone, she very well could take control of her again at any moment.
