"Arresto momento!" Rosalyn heard Hermione shout through the air rushing through her ears.

Thankfully, this did the trick, as about a foot from the ground, everyone stopped for a second, breaking the impact, then all seven of them fell on the rock that covered the ground. Rosalyn breathed hard, still clutching the prophecy, before she started to get up.

"Department of Mysteries?" Ron asked. "They got that right, didn't they?"

Rosalyn wasn't compelled to laugh. She couldn't stop thinking about how she'd nearly killed everyone that was standing beside her.

And that they still weren't in the clear.

A stone arch with a veil in between it stood in the middle. Well, a veil that looked like smoke. And Rosalyn walked up to it.

"The voices," she said, advancing on the veil. "What are they saying?"

She wasn't lying. She actually heard voices coming from the veil, but Hermione didn't. "There aren't any voices, Rosie, let's get out of here."

But Luna Lovegood stepped up. "I hear them too."

"Rosie, it's just an empty archway," Hermione said, her voice shaking. "Please Rosie!"

Suddenly, Rosalyn heard something else. She turned, hair flying, eyes cold, wand up, yelling. "Get behind me!"

The six others raised their wands and ran behind their leader. Rosalyn saw the Death Eaters start to descend, their immaterialised form of black smoke coming down from the door.

Suddenly the seven teens were encased in the smoke, and they pressed themselves into the rock to try and escape it. Rosalyn still had the prophecy in her hand, terrified that someone was gonna wrench it from her grip.

And then the smoke subsided, but everything had changed. Rosalyn quickly became aware of the fact that she was alone, and when she looked up, her blood ran cold.

Around the circular room, all six of her friends were getting held by death eaters, wands pointing at their heads.

A cold laugh filled the air as Lucius Malfoy walked up the rock, leaning on his cane. "Did you actually believe... or were you truly naive enough to think... that children stood a chance against us?"

He was above Rosalyn, putting his hand out. "I'm not giving you-" Rosalyn started to murmur, barely moving her lips.

"Oh, I know you won't do it for yourself," Lucius said, tones of malice embedded in his voice. "But you've brought weaknesses here, Potter, people you can't bare to watch as we end their lives..."

Rosalyn's eyes became a bit wider, realising. "I'll make this simple for you Potter... give me the prophecy... or watch your friends... die."

Rosalyn looked around the room, and everyone looked petrified.

"Don't give it to him!" Neville yelled, but Bellatrix, who was holding him, hissed a shhh, then put her wand across his throat.

Rosalyn knew what she had to do. Ignoring Neville, she handed Lucius the prophecy. In his short moment of glory, he held the glass ball up, savouring it.

His short moment of glory.

"Get away from my goddaughter."

Rosalyn saw Sirius for a split second before he punched Lucius in the face.

Rosalyn didn't know that the order could do the immaterialising thing, but with white smoke, however they could. So soon Izzy, Tonks, Kingsley, Lupin and Moody were before them.

Lucius Malfoy, meanwhile, was on the ground, and he saw the prophecy smash right in front of his eyes. Rosalyn would've laughed if she'd seen.

Right now, Bellatrix was going after Tonks, who was hiding Ginny and Luna, Harry, Hermione and Ron were fighting, and Izzy was helping Sirius and Rosalyn, who were running from spells.

Eventually, the three of them got hidden behind a rock, Sirius and Izzy turning to Rosie.

"Now listen Rosalyn," said Sirius warily. "I want you to take the others and get out of here, d'you understand?"

"What? No! I'm staying with you," Rosalyn said.

"You've done brilliantly, Rosie, but let us take it from here," Izzy reassured her.

But before she could say anything, Lucius and another two death eaters were drawing their wands, and Rosalyn, Izzy and Sirius had to duel them.

The death eater, Dolohov, fired at Rosalyn, who was covered by Izzy. The six of them continued to duel whilst Moody fought with his cane and trails of black and white smoke which were Tonks and Bellatrix, raced around the room in a deadly chase.

"Stupefy!" Rosalyn yelled in the meantime, sending Dolohov flying backwards. Then she shouted. "Expelliarmus!"

Lucius' wand fell out his hand.

"Nice one-" now, what Sirius said next was always up for debate. Rosalyn would always swear he said "Lily", her mother, and he had made a mistake. Sirius would swear he said "Rosie", his goddaughter's name.

Sirius and Izzy finished it off with non verbal spells, sending Lucius flying across the room into rough rock. He landed hard.

"Avada Kedavra!"

Rosalyn wasn't aware of Bellatrix yelling those words, but next thing she knew was that Sirius was falling backwards into the veil. And the veil was taking him, dragging him upwards.

And then the full bleak daylight struck in, and Lupin had to hold Rosalyn back so that she didn't run into the veil and follow her godfather.

"NO!" She screamed. Tears poured down her face and her body ached, but she kept yelling. "NO! P-PLEASE! LET ME GO! LET ME GO!"

"Rosie," Izzy said from a few metres away, tears streaming down her face as she had just witnessed her husband's fate. "There's nothing you can do... he's d-"

"HE'S NOT DEAD!" Rosalyn roared, surprising herself with how loud her voice was.

Then she saw Bellatrix Lestrange, escaping. And Rosalyn suddenly built up enough strength to throw off Lupin. Strength from rage.

"I killed Sirius Black! I killed Sirius Black!" Bellatrix shrieked. "You comin to get me?"

At that moment, Rosalyn was wracking her brains for a spell that would cause Bellatrix as much pain as possible. She was so overcome with grief that she didn't care if she was breaking the law.

"Crucio!" She screamed, sending a jet of red light at Bellatrix.

The woman went down, screaming, but only for a few seconds.

Rosalyn didn't understand, when Voldemort had done it to her, she had been like that for at least ten seconds.

"You've got to mean it, Rosalyn. She killed him. She deserves it."

Suddenly a cold, high voice was speaking to her. It was in her head and she couldn't escape it-

"You know the spell Rosalyn..."

Her wand was still pointed at Bellatrix when the woman started to laugh.

"Do it."

Rosalyn turned round to see Lord Voldemort, standing behind Bellatrix. She tried to cast a spell, but Voldemort disarmed her easily. "So... weak."

Rosalyn didn't know what to do. She couldn't defeat Voldemort. The only one he ever feared was...

And then the only one he ever feared was there. Dumbledore came out of a fire, covered in green flames.

"It was foolish of you to come here tonight, Tom," Dumbledore warned, stepping in front of Rosalyn. "The aurors are on their way."

"By which time I shall be gone, and you... shall be dead," was Voldemort's answer.

Dumbledore raised his wand above his head, circling it, starting a duel. Bellatrix was pushed into the fire, green flames swallowing her up. Rosalyn was pushed to the side, out of the way, hopefully shielded.

Flashes of green and red light were flying as two of the greatest, most accomplished wizards (be it good or bad) duelled furiously.

The whole Ministry was falling apart with windows, bricks and ornate things like the fountain were getting blasted into nothingness.

Rosalyn covered her ears and hid her head whilst Voldemort blew a massive fireball at Dumbledore. The fire, however, soon took on a life of its own, becoming a snake.

The snake reared and went for Dumbledore, but Dumbledore destroyed it by crafting the water from the fountain into a ball and sending it at the snake. It destroyed it, and then he drenched Voldemort.

Voldemort fought back. He splattered the ball of water, sending a tidal wave through the Ministry.

The spell he used next, Rosalyn didn't know, but she saw that Dumbledore had to fight to stay standing, and that the remaining windows smashed with a vengeance.

Smiling, Voldemort put his hands up, wand between them. He sent all the broken shards of glass at Dumbledore, laughing loudly. Dumbledore put shield up, but the glass penetrated it, defied it. Rosalyn hid her face, determined to block it all out-

Everything stopped. Voldemort's laugh, his spells, everything. And then he disappeared.

Rosalyn stood there in shock, her head pulsating from all the shock. Then she felt thoughts overtake her emotions and she fell.

"R- Rosalyn-" Dumbledore knelt down beside her.

"You've lost, old man."

The voice that Rosalyn spoke with wasn't her own. And when she looked up, Dumbledore understood why. Her eyes were not her own either. They were green and red, bloodshot. And they belonged to the man he had been duelling ten seconds ago.

Rosalyn screamed as memories went through her... Cedric... killed at the graveyard... Sirius falling through the veil... her mother, Lily, screaming... begging for mercy...

"Rosalyn..." Dumbledore said helplessly, as Harry, Ron, Hermione, Neville, Ginny, Luna and Izzy arrived at the scene.

"So weak... so vulnerable..." Rosalyn heard Voldemort say as more memories jolted through her. "Look at me..."

When she looked in the Mirror of Erised... her face was Voldemort's...

"Rosalyn... it's not how you are alike, it's how you are different that counts," Dumbledore said, trying to help the girl lying beside him. "Rosalyn..."

Older memories... Hermione hugging her... after she had defeated Tom Riddle... the quartet laughing in the snow... after she had tricked Malfoy with the cloak...

Then it wasn't Dumbledore above her, but Voldemort. Rosalyn was sure this was real, and not some stupid dream... "You're a fool, Rosalyn Potter, and you will lose... everything."

But then the fires started to rumble, and all of a sudden Ministry workers and officials saw Voldemort, a second before he disappeared.

"He's back," Cornelius Fudge, who was at the fore of the group, whispered.

Rosalyn and Dumbledore got on the front page of the newspaper as he carried her to the fire, using floo powder to get back to Hogwarts. He didn't speak to Fudge, he had since then learned not to.
