"She was raped, raped by a powerfull demon worshiped by women as a fertility god. They didn't always get pregnant, in fact they almost never did. Women you see have an incredable power, the power to make men do incredable things that normally would be impossible. The power to increase a mans will ten fold so that a wound that should drop them will only slow them, if even that. These powers are passive, and undetectable, but their reall power is life. All women have power over life, their the only creatures that can create life. This demon, Akuza I believe, built himself a temple that amplified his powers of seduction, he did this so women would be more willing when he took them. Afterwards the women in question were affectively immune to sexual impulses, never able to meet a man who can satisfy them. When they do the man is incredably powerfull, and their seed is transformed into raw power, using the women as a focusing lense. The women eventually get pregnant, and bothe they and the child always die in labor. It's a method to gain their power and the inherited power of the man, increasing his own power. I am the most powerfull being in the world, and he had enslaved somone I cared for, so I destroyed him, his followers before they fell imprisoned me, but like I said the temple was built to amplify his powers. He fed on life, and it's quite possible his essence remains, or I should say remained, and is now pickabacking in her power, hiding behind the barrier you set up. He also holds a small amount of my power, that would be enough that given time, he can re-incarnate himself and it will destroy the host. The only thing we can do is either attempt to purge his essence, or force an emergence and destroy him before he can fully form. The first method is safer, but there's a chance I might miss some of his essance, the second choice is riskier, but if successfull, will destroy him completely."
