Gracie will be able to accurately control her location in space, and will be able to use this to enable herself to levitate or fly by preventing her location from altering as it would do if she succumbed to gravity and fell. She will also be able to control the direction and speed of her flight by changing the location. However, she will not be able to change her location at such a speed that it would resemble teleporting, and she also won't be able to affect the locations of others.
