Sirius Black didn't feel right. Something was wrong. Something was terribly off when his best-friend James Potter finally showed them the house that he bought for his wife and his future children. The house was a two-story, the painting of the house was old and chipped, but with the right spells that house would be good as new once more. Remus Lupin stuffed his hands into his pocket, freezing, as a snow flake fell on top of his sandy hair. He shook his head, he always hated the cold weather. James walked up to the small, fenced gate. The gate was muggle-like and like the house it showed some wear and rust from age. He was excited, Sirius could tell, but Sirius couldn't help but noticed one person that's missing. One person who kept on bailing out of plans with them for months now. Sirius thought that Remus would be the first one getting suspicious of his rat like friend, but he was wrong. The werewolf always found a way to excuse him. James haven't even noticed that Peter had cancelled, but Sirius did.

Where was he?

Why was he gone so much?

"So what do you guys think?" James asked, and Sirius let out a barking laugh, "I can't see you living in a place like th-" That was when it happened. Sirius's laughter stopped. A few shrieks echoed through the night sky. Muggles ran, obviously terrified, out of a nearby store. In hot pursuit of them were hooded figures that were trailing behind the Muggles like poisonous snakes. Sirius paled. Death Eaters. They sent off spell after spell after the retreating muggles. Defenseless, they fell limp to the harsh ground. The Marauders took out their wands. Gone was the laughter and the excitement and was replaced with fear. The Death Eaters, three in a group this time, turned their backs on the muggles and they seemed to march towards them with haste. James ducked into his yard, pulling both Remus and Sirius with him.

It was like they knew that they were here.

It was like they knew where James had just purchased the house for his upcoming family. The first Death Eater, Sirius knew well, even behind his golden mask, stood Avery before him. Both at a stand-off, they both flickered their wands with a non-verbal spell.

Sirius used the shielding charm just in time against Avery's slicing hex, making his hex fade into bright red particles. Avery and Sirius continued to duel till his partner finally arrived next to him which Remus finally jumped in stunning them. The two figures dropped stunned on the snowy ground, but they knew it wasn't over yet. There was one more.

"Expecto Patronum!" A bright blue glowing stag appeared before James.

"Tell Dumbledore that they're here."

The blue stag took off in a gliding run into the night sky, toward Hogwarts. James sighed in relief that he decided that Lily wasn't with him. Just when everything was quiet down the third Death Eater revealed himself to them.

"Cruico!" The Death Eater hissed and Remus went limp to the floor twitching. A horrible screech left his lips as the terrible pain writhed like a fiery monster within his bones.

"Moony! Diffindo!" Sirius shouted, but then the amazing thing happened. The Death Eater blocked it with a swift shielding charm. The pain died down, leaving Remus on the snowy ground twitching with a hollow breath.

"Potter and Black, think you can finally defeat me?" the Death Eater mocked.

"Who are you!?" James bellowed and then the Death Eater paused. He tilted his masked head.

A few golden strings of hair showed down his hood.

So familiar.

"You would like to know," he replied coldly. As darkness filled every corner of the Marauders' visions, they fell into peaceful oblivion, knowing no more.

Hermione Granger stared outside of her tent. She sat down on the steps and she was lost in a small daze. It had been two days since Ron left her...left Harry and her heart felt empty besides sorrow. She felt the will to fight left her when minutes turned into hours and hours turned into days, but she forced herself to keep going. Harry needed her. The moment that Ron left, her heart shattered. He abandoned them, something that he never would have done years ago. It took Hermione two hours a day to set up the wards around their camp site with complex protection charms and warding. They were heading to Godric Hollow, to see the author of Hogwarts, a History and Harry parents' graves.

"Mione, go get some rest." Harry's gentle voice said to her from behind. His hand was on her shoulder comforting. He knew the lost of Ron had broken her. He saw it within her eyes each time he looked. It was like she wasn't there. A minute passed by, before Hermione nodded her head agreeing to him. They would have to pack up camp early in the morning, if they want to keep on dodging the snatchers. Hermione stood up and then the ground rattled. She fell and Harry's strong arms wrapped around her waist held her up.

The Wards began to crumble. They both pulled out their wands searching the campsite to find the cause of such disturbance. The cause on why their wards had failed. This would alert anyone close by to their location. Harry held Hermione behind him. Sneaking around their tent slowly, they both stood in shock. There laid three young-men passed out. Their was a huge hole in the ground under them. The trees began to rattle. It was only a matter of time.

"Bloody, hell." Harry ran beside the three strangers. His wand still pointed at the lot. Their chests began to heave and Harry knew they were still alive. He struggled. They were in a middle of a war. There isn't much time for trust these days. These people were strangers, but somehow they looked familiar to him. He heard Hermione's voice behind him.

"Leave them to me Harry, pack up the camp." Hermione's always steady voice calmed his panicked, erratic one. His green-eyes searched Hermione's chocolate orbs and found determination. An emotion other than the sadness she had displayed for days.

"I'm going to bind them, but we need to get out of here."

Harry agreed, hearing the trees begin to shake and tremble as heavy footsteps echoed through the vicinity.

Hermione tightly bound the three young mens' arms and legs together so they wouldn't be able to move once they came back. Harry had just finished packing the tent when he saw golden eyes within the right side of the camp.

"Hermione! Now!"

He ran forward grabbing her hand. She had attached the binds to connect the strangers. She took one of the stranger's hand trying to focus all her might. It was hard to side-along apparate them all. She heard Fenrir Greyback growled in a distance. Harry's hand tightened around hers.

POP!

Harry let go a minute later and they both stumbled forward. Harry searching his surroundings to see what he's at, realizing he was in his godfather's house. Hermione intended to come here. The last of the trio stood up wobbling on her feet. The three strangers still appeared lifeless before them. Then someone roared loudly overhead.

Both Harry and Hermione stood on their feet in fear.

A diaphanous, ghostly illusion of Mad-Eye Moody came flying threateningly towards them, screeching viciously.

"Finite Incantatem!" Hermione cried, quickly flicking her wand and soon the illusion of Moody faded. There was silence at last and both the members of the trio sighed in relief.

"Must be a last security measure for Snape," Hermione uttered and Harry nodded his head.

The beating of their hearts slowly died down to a steady pace.

Then a portrait directly to Hermione's left began to scream.

"FILTHY MUDBLOODS AND BLOOD TRAITORS!" The open painting of Mrs. Black roared loudly into the silence and Harry flinched. Her voice went louder and louder with each word.

"For Merlin's sake SHUT UP!" Hermione screamed pulling back the curtains over the painting. The screams of Mrs. Black died down to nothing.

"What now?" Harry asked pointed at the three strangers on the floor.

Hermione paused her lips,

"Homenum Revelio"

Harry looked at her confused.

"To see if anyone is here with us." Hermione explained. When the spell gave her no results, she finally smiled sadly.

"No one's here except the five of us."

Harry walked over the three bodies.

"What are we going to do with them?"

"Put them each in a room, warded. Since we don't know who they are." Harry said, looking down at one of the strangers with short dark brown hair with hazel eyes. He looked like the perfect twin of Harry except the eyes of course.

"We should be safe here." Hermione said, warding the place with anti-apparition charms.
