Fleur soldiered on, long fatigued from eons spent inside that insidious maze. The mist and constantly shifting hedges provided a cover, allowing for no passage of time to be obvious. All she knew was the strength of her spells were starting to abandon her. Turning a corner, the eerie green glow of the Killing Curse stares; removing all motion from her limbs.
The world stops.
Ever slowly, that insignificant ball of light almost eagerly leaves the end of Krum's wand inching it's way towards her. The warping of time around her is barely noticeable in the face of certain death. A hair’s breath from it reaching her heart, she gives in, eyes shut. Deep within her very soul the cry of her ancestors rings forth.
She opens her eyes. Expecting the beyond, she instead finds the world wreathed in her flame. Hovering above the hedges she is the nexus of an enormous flame. The doom and dusk of mist once masking the passage of time is gone; Now it is the world alight with her ethereal flame halting the very fundamentals of reality. All except for one speck in the corner of her eye. Turning about she finds Harry Potter. It's clear from his outstretched wand he'd tried to do something: either in protection or vengeance of what should have been her death.
Eerily, he was the only thing her fire has not enveloped. But a section was formed only a needle's width and diving towards his third eye. That's the only thing that is moving. As Fleur dove down to stand in front of him, the needle point of fire made contact and Harry began to blink.
