Prologue
-Ministry of magic~1995-
A red haze falls over Rosemary's emerald green eyes while rage courses through her veins, as she chases Bellatrix lestrange nee Black, one of Voldermort's most known and loyal followers, through the corridors of the ministry of magic; snarling in frustration as she once again hears Bellatrix shout out tauntingly about killing Sirius Black causes her impulsively cast the first spell that comes to mind, which just so happens to be one of the three darkest curses created in wizarding Britain. With a rage filled scream of "crucio" a sickly red light flies from Rosemary's wand and hits Bellatrix in the back, making her fall to the entrance hall floor with shrill squeak of surprise
Rosemary comes to a swift stop at Bellatrix's feet her wand never once leaving it's pointed position towards Bellatrix, while at the same time said women slowly turns over to lay on her back before sitting herself up and staring up at Rosemary with shocked disbelief in her crazed brown eyes. For the next few seconds or so the pair, one whimpering slightly and the other panting in anger, stare at each other intensely. "You've got to mean it Rosemary. She killed him! She deserves it! You know the spell Rosemary," is whispered into Rosemary's ear causing her to whip around to look behind her. From a mass of black smoke emerges Voldermort in all his deformed snake-like glory with a strangely happy and cruel smirk on his lipless mouth, all the while you can hear Bellatrix's shrill and crazed laughter echoing through the hall once she caught sight of her lord and master.
"Do it!" Voldermort orders as Rosemary looks back towards Bellatrix only for her to point her at Voldermort, who with a grunt and a wave of his hand disarms her making them both watch as her wand flies through the air and lands on the black tiled floor with a echoing clatter. "So weak," He purrs as he stares at her with false pity on his face and a triumphant and sadistic gleam in his dark blood red eyes. Suddenly one of the fire places sprung to life in a flash of green flames and out steps Albus Dumbledore with a frown upon his wrinkled face, "It was foolish of you to come here tonight Tom. The order is on their way," Dumbledore declares as he stops beside Rosemary with his wand pointing towards Voldermort. Said man just glares at Dumbledore and sneers, "By which time I shall be gone and you shall be dead." With that said Voldermort and Dumbledore, who pushes Rosemary to the floor and out of the way, begin to duel while Bellatrix sees this as a chance to escape leaves through the floo in a flare of green fire.
As Dumbledore's and Voldermort's spells connect Rosemary watches in fear from beside a fireplace as they try to over power each other with their chosen spells; grunting Voldermort breaks their connection and breathes a ball a golden-orange fire into the palm of his spidery hands. Dumbledore stares wide eyed, with Voldermort laughing fiendishly, as the small ball of fire grows and changes shape into that of a huge basilisk. The fiery snake throws itself towards a shocked Dumbledore with the intent to kill only to have Rosemary launch herself off the floor, and push him out of the way snapping Dumbledore out of his state of shock. Quickly seeing the snake heading their way Dumbledore moves Rosemary to stand behind him, and with a wordless everte statum throws the snake backwards before dis-spelling it completely. He then points his wand at the fountain of water, that Voldermort is standing in front of, and with flick of his hand the water raises up from the fountain and encases Voldermort in a large swirling ball.
Dumbledore's concentration is broken when hearing Rosemary yelp, as she trips and falls to the floor, causes him to look behind him to see if she's ok, which in turn causes him to unintentionally stop his spell letting Voldermort fall to the floor with a wet thump. Voldermort quickly rights himself before firing an unknown spell of a congregate black tar like substance at Dumbledore and Rosemary in rage filled retaliation, only for Dumbledore to throw up a wordless protego horribilis to block the obviously dangerous and dark spell. Seeing that his spell wasn't work Voldermort hisses in anger as he stops his spell with a harsh wave of his wand and narrowed eyes, the backlash of power from the spell sweeping throughout the hall and braking every office window in the entrance hall to pieces.
Dumbledore instinctively places himself over Rosemary to protect her from the pieces of glass raining down upon them, just as the fireplaces, placed throughout the length of the hall, come life with a loud whooshes. A large group aurors, the press and the minister himself, Cornelius Fudge, step into the hall only to stop in fear once they see Voldermort standing in front of the now empty fountain with a angry sneer on his face. The sneer immediately turns into a cruel smirk as Voldermort waves his wand to redirect the glass towards Dumbledore and Rosemary with the intent to kill, only for Rosemary to notice this and shout Dumbledore's name causing him to look up towards Voldermort and quickly cast a slivery-blue shield around them.
Once all the glass that's passed through the shield has disintegrated Dumbledore dis-spells the shield, only to hear Rosemary's scream of "NO" before a sharp fiery burning sensation to consume his throat. Everyone could only watch in horrified silence as Voldermort fires a wordless "diffindo" at a distracted Dumbledore, the spell cutting off his long beard and hitting him directly in the throat. Slowly he brings his pale shaking hand to towards his neck before looking down to see blood covering the front of his pale green robes. With a loud thump he falls to the tiled floor in a heap bloody robes, blood quickly beginning to pool around him and soak Rosemary's jean clad legs as she kneels next to him stupefied.
The hall begins to blur when tears fill Rosemary's eyes and begin to slide down her pale cheeks, 'Please no! No! He...They...They can't! Sirius, Dumbledore why?! Why them?!' Are the thoughts that are going through her head as she stares silently at a now dead Dumbledore. Suddenly Voldermort's insane and triumphant laughter brakes through the foggy haze surrounding her mind, and the pure rage she felt earlier floods back to the forefront of her mind causing her heart pound erratically within her chest. Quickly she shakily stands up from her kneeling position and screaming rage and grief driven yells of "expelliarmus", "incendio" and "Avis" brings Voldermort's attention back to her, just in time to deflect the first spell and dis-spell the second and third ones. With his attention on the first three spells Rosemary quietly whispers "Stupefy" that catches Volermort completely off guard causing him to freeze in place. Rosemary, after staring slightly at Voldermort in surprise, wastes no time in casting what she hopes is to be Voldermort's ending blow, so with a harsh wave of her wand and a yell of "sectumsempra" a small white light flies at Voldermort hitting him directly in the head.
For the next few seconds everyone within the hall stares at Voldermort waiting for something happen, when it's doesn't people start whispering to each other and Cornelius decides to take things into his own hands, "Arrest hi..." He begins to order only to be interrupted by a chocking noise making them turn their attention back to the pair. Soon everyone is stunned into silence as they watch Voldermort's head fall to floor with his body following not even a second later. It's shortly after that the words "she did it", "you-know-who is dead" and "Rosemary Potter killed You-know-who" is being shouted throughout the hall, as the press and aurors surround her with the intention of congratulating her or in the press' case an interview on how she did it.
Rosemary ignores it all to gaze in absolute shock at Voldermort's dead body as thoughts of disbelief fly through her head, 'I did it! I finally did it, I killed him!' Her thoughts quickly turn into ones filled with happy relief causing her to suddenly laugh uproariously, 'He gone. I'm free. I'm free to be normal again. I'M FREE!' Oh if only she remembered at the time that nothing is normal when concerning herself, because as they say when one adventure ends another is surely to begin.
