Unspecified Place, Unspecified Time
The Sorcerer Supreme looks around, barely managing to stand up on his own. He is weak, having just fought a near omnipotent, multidimensional fire being. On his own. He thought he would have had help from his Avenging teammates, but unfortunately, said fire being gained control of one of his said teammates, and, under its control, she managed to utterly defeat the rest of the team. She fainted as soon as the Sorcerer defeated the fire being, as its control had expended all of the hero's energies. The Sorcerer knows that the world is saved nonetheless, and the people of his world will live on. Still, there are other issues to be dealt with, such as the problem of the superheroine who managed to take out an entire team of superheroes by herself. The Sorcerer knows from experience that once one is exposed to the control of the Fire Being known as Dormammu, it is nigh impossible to destroy that connection, which is something Dormammu always comes back to exploit. For he can only physically wreak havoc upon our dimension if someone summons him, and the easiest way to do that is to exploit a connection made while in this dimension before he is banished. Keeping her around would be dangerous for the future of all mankind. Thus, he has to do what he must. He walks up to the girl and summons a energy spear (for he can do that with his magic powers), raises his hand to strike, and...stops. He cannot do it. He only met this girl a year ago, and yet he knows that she has so much more for her life in store. She's still just starting her life as an adult, he thinks to himself, so much untapped potential. He thinks of how she spoke of her recent engagement to her lover that morning. Can I really just take her opportunities away from her for something that wasn't her fault? He stops and dissembles his energy spear. Still, he knows she cannot be let alone with this new power. Were Dormammu to exploit it, Armageddon would arrive swiftly after. He ponders what to do for a moment, the comes up with an idea. I know, He thinks to himself, his genius beginning to flow, I'll wipe their memories. The only people who know of the Avengers' defeat at the hands of one of their own are all right here. I must take special precaution with the young woman, though, as she's the one who has the power to destroy, albeit unknowingly. Curse Dormammu and his transdimensional abilities. Somehow, I must keep her under my supervision so I can insure that she doesn't summon the Fire Being. Ah. I know how...A simple fake memory or two will get the job done. Perfect for the fake memories I need to cover up what I erase. Maybe a few other tweaks will have the power to save us all...
The girl, known to the public as Spider-Woman, known to her friends and family as Gwen Stacey-Parker, sleeps on, unaware of what falsehoods the Sorcerer places in her mind in the name of her wellbeing, as well as the universe's.
