Where do the Limits Lie?

Maxsodin screwed up her face, staring at the thing.
So weird..., she thought.
She jerked her hand to the side again. It followed. She yanked it to the other side. Again, it followed.
She pulled back, her hands meeting at her chest, and shoved forward. It exploded, filling the room with heavy black mist.
Intrigued, Maxy began moving her hand in a swirling motion. The mist swirled and began to gather back into the black ball again.
Maxy stuck her tongue out in concentration. Her skull began to pound. Softly at first, but harder as she stilled controlled the black ball. She used both hands now, controlling its path across the room.
With a yelp, Maxy fell to her knees, catching herself as she did. She looked up to see the ball fade swiftly and was gone.
Drat, she thought bitterly. She rubbed the back of her head, soothing the immense pain.
Maxy heard something. It was faint, but it was there. Strange, almost inaudible whisperings. It seemed to come from all around. It grew gradually, filling the room as it did. Maxsodin felt pressed by the noise as she felt it engulf the entire room around her.
Letting out a gasp, Maxsodin blinking heavily. The room had fallen silent again. She no longer felt confined.
Shaking her head, she tried not to remember the noise. It reminded her too much of when the Darkness would cause her to black out.
The door opened.
Maxy's Keyblade unconsciously appeared in her hand as she whirled around at the sound.
And there, framed in the doorway, was Daxjorn.
