I don't own anything from this story other than the OC.
Enjoy!
"What are you going on about now Ron?" Hermione asked as they sat around a table.
He looked at everyone and waved his arms animatedly, "Haven't you guys noticed someone weird around Hogwarts?"
Harry chuckled, "There's always someone weird around Hogwarts, Ron."
Said boy shook his head, "No, I mean within the last year, someone always wearing a cloak and only coming out long enough to talk to a professor then disappearing."
"Well, I doubt they're evil if they're talking to all the professors," Mrs. Weasley said as she placed food on the table for lunch.
They seemed to think about it until the twins sat down. Fred grinned, "We know who you're talking about."
"We tried to follow them around last year-"
"-but they completely gave us the slip before we could see who it was-"
"-We must have bugged them enough-"
"-because they turned to glare at us and we caught a glimpse of their eyes."
Ron leant forward, "Well, what did they look like?"
George shook his head, "Patience is a virtue Ronniekins."
Before Ron could go after his brother Fred spoke up, "They didn't seem exactly mad at us-"
"-because we could see a smirk."
"But their eyes reminded us of a reptile's eyes."
Everyone was quiet, thinking about this new bit of information, sitting around the table eating when Harry leant forward and held onto the table. "Harry?" Ron asked concerned.
Said boy looked around at everyone, "It's Voldemort, something's happening to him."
Several of the people jumped up as an owl landed with a letter. Remus was closest and read the letter then stood, "Everyone, to Hogwarts. Dumbledore needs us there. Voldemort's there."
Harry, Ron, Hermione, and Ginny stood up until their mother gave them a look, "You children are staying here."
Remus shook his head and held out the letter, "No, he expressly said for everyone in this house to come. Even them," he motioned to younger ones.
They didn't have time to think as the aurors quickly latched on to the ones who couldn't apparate and arrived at the entrance to Hogwarts where Dumbledore stood, alongside all the professors and someone they didn't know. "I'm glad you all arrived so quickly. He's making his way up here now."
A sudden sound in front of the group announced the arrival of the Minister of Magic, along with a few others, "What is the meaning of this Dumbledore? I'm very busy and don't have time for this." That's when he noticed everyone looking past him to the bridge leading to the school and gasped, "This isn't possible."
"I'm afraid it is Minister," Dumbledore spoke up as the people from the ministry moved closer to the group, "But he won't be a problem much longer. I must advise, however, that you all stay as close to me as possible and do not stop anything that is about to happen for it may have dire consequences."
"What happened? It felt like something was hurting him," Harry asked as he stood beside the Headmaster.
The older wizard nodded, "That's because something was hurting him. His snake, Nagini, was a horcrux. She has been destroyed." He looked over to the hooded figure and nodded then looked over to Professor Mcgonagall, "Minerva, you know what to do now."
She nodded back and gave the hooded figure a small smile as she called all the armored statues to arms then began to make a barrier around the school with the help of the other professors.
Ron nudged Ginny and Harry, "There's that cloaked figure."
Ginny looked over and eyed her twin brothers, "You don't think they're going to pull the hood off, do you?"
Harry shook his head, "Knowing them two, I wouldn't put it past them."
Before anyone else could do anything, Voldemort was finally there. He held a sneer as he noticed Harry before looking back to Dumbledore, "I see young Harry Potter is here ready to die."
"I'm afraid Tom, that will not be happening anytime soon," the older of the two spoke.
Voldemort noticed the hooded figure and glared and pointed towards them, "You, have been a nuisance since last year to me, which is why, I think, I will kill you first." The hooded figure was between the twins, who were silently debating on what to do with the cloak, then glanced back and forth between the unknown person and the Dark Lord. Dumbledore chuckled softly. "You should not be laughing, Dumbledore, you'll be next."
The hooded figure tensed as smells surrounded them until Harry went to step forward, "No my dear boy," Dumbledore held up his hand to stop him and spoke softly so only the group around them would be able to hear, "My friend here will be handling him. They have a unique trick or two up their sleeves to keep from dieing. I've received letters from several reliable oracles that if any of you fight, most will die which is why we managed to bring him out early before he has built up his army."
They all looked at him until he nodded to the unknown person and smiled reassuringly, "Whenever you are ready, my dear."
They watched as the person nodded, chuckled softly where only the twins could hear, and walked forward with a single purpose in mind. Voldemort grinned, "So glad of you to come meet me to end your life. But I would like to see whose life it is, I'm about to end."
Several of the aurors looked nervous as Professor Mcgonagall stood beside the Headmaster and asked worriedly, "Are you sure this will work Albus? After all, she's still a child."
"I have all the faith in the world that she'll be fine," he answered as the teens gathered together.
The Minister's face grew red as he rounded on Dumbledore, "You cannot send an underage witch to face him on her own! I will have her wand and have you put on trial for this."
The Headmaster gave him a knowing look as several people scoffed at him, "She is the only one who can overtake him without having to sacrifice something in return. Believe me when I say: that sending her out there is the last thing that I want, but once she found out how many lives would be lost she has argued to the point if someone other than her does this that she'll hurt them." He sighed and looked out at the girl, "She has been trained in secret by all of the professors, including myself, during the holidays and is more than capable of handling herself." Dumbledore smiled, "Voldemort doesn't know what he's getting himself into with her. But I accept full responsibility if anything does go wrong."
Ginny lent closer and muttered, "A girl?"
The twins shrugged, "Could be, they were shorter than us."
The Headmaster chuckled, "She's actually the age of the twins." This made everyone's eyes go wide.
Some movement caught everyone's attention as the figure did a mock bow and acted like they were about to remove their cloak when they quickly threw two daggers away at opposite ends of where the others stood with the blades in the ground.
Ron's eyes grew wide, "They're mental if they're fighting him without a wand."
Voldemort's grin turned into a frown and yelled out, "Crucio." It hit them dead center and they fell to the ground quickly, making him laugh and look back to Dumbledore, "Is that the best you have? It's a wonder this person has survived this long. No matter, no matter," he walked closer to the still figure until he stood a few feet away, "They will not be a bother any longer."
"Move!" several people yelled.
He raised his wand and glared, "Avada Kedavra!"
