Lady Macbeth
The Lady knows the stories: how her eyes induce madness in men.
The Lady knows she will be wed to the Scottish brute, who does not leave his warrior ways behind when he comes to the marriage bed.
The Lady knows his hostile, suspicious court will be a game of strategy, requiring all of her wiles and hidden witchcraft to survive.
But the Lady does not know her husband has occult secrets of his own. She does not know that prophecy girds him like armor. She does not know that her magic is greater and more dangerous, and that it will threaten the order of the world.
She does not know this yet. But she will.
