Sweat dripped down Persephone Dialore's face as she tried desperately to finish the preparations. Though she was not a very gifted Seer, she knew enough about her husband to know that he was coming for her. He did not want her to finish her task. He was going to kill her before it could be completed.
Persephone would not normally care if he killed her. She was planning to kill herself as soon as everything was ready, but if he killed her…all of her plotting would be for naught.
She had always been ashamed of what a poor witch she was. Not able to do anything above average, never able to do what her heart truly desired. She knew how, she doubted if anyone alive knew more about Dark Magic than her. Well, except perhaps Grindelwald. But her husband had always been too weak of character to do anything with his power. He always talked about waiting for the opportune moment to try to take on the entire wizarding community. Persephone was tired of waiting.
She rested her hand on her bulging stomach. She could not do what she wanted, but her daughter would be able to. As soon as Persephone finished the potion and drank it, everything would start to play out just as she wanted it to. The potion would enable her daughter to absorb power from other wizards, to turn curses and spells into power for herself. No one would be able to rival her. She could fulfill her mother's dream and declare herself the supreme ruler of mankind. Even her name, Minerva, supported her eventual reign. The warrior goddess.
The potion was ready. Persephone poured it into a glass and forced it down. She screamed. Even as the potion touched her lips she felt her power being drained. Grindelwald burst into the room. "Persephone! No!" He saw that she had already done it. "You whore! You filthy whore!" He raised his wand. "AVADA KEDAVRA!" he roared.
The room was filled with a bright green light as Persephone let out a blood-curdling shriek. The sound of a baby's crying rang sharply in the air. Persephone let out a last moan and rolled onto her side.
Grindelwald stooped down and picked up the baby, completely ignoring his dead wife. He held Minerva in his arms with a demented smile on his face. His plan had worked out exactly. Persephone had sacrificed herself to make her child supremely powerful, and one day Grindelwald would harness her power and claim everything for himself.
Although Grindelwald knew what the spell would do, he was still extremely startled when the baby opened her eyes, eyes of an unearthly green color, much like the light from the killing curse.
