Harry Potter and the Fight of Two Generations

What would happen if Harry grew up with both of his parents and lived in a magical world since birth?

October 31st, 1981

The Potter Family was settling down for a supposedly uneventful evening when a caterwauling charm was set off down the street in Godric's Hollow. A sharp snap in the air would have masked the sound of any apparition but the shabby robes and worried face was enough to startle the two Potters. The two men held their wands in attacking position aimed at each other's head.

"The names we gave ourselves in Hogwarts" The dark-haired man asked. "Moony, Padfoot, Prongs and Wormtail". James lowered his wand and greeted his old friend. Remus' face kept its worried shape. "He's here." James sprang into action.

"Lily, get Harry and cast the charm we practiced, I'll distract him." She nodded knowing that her husband could handle himself, but she still warned him to be safe. "Remus, how did he know"- James said before being cut off. "It was Peter. He spilled everything to Voldemort. Sirius patronoused me after he found Peter out and told me everything."

"Why meet here Peter, why not somewhere secure like at James and Lily's?" A shaggy haired man asked the quivering wimp. "You killed them Sirius, you gave them up to Voldemort! You betrayed them!" Peter put on his best act and dramatized his voice and actions out of nowhere. "What are you talking"-. Sirius had realised what he had done. He threw a shaking Wormtail up against the wall and started to draw his wand. Peter already had his drawn and fired a quick exploding curse over his shoulder, behind the wall. It struck a large area and Sirius stared in horror at what his once friend had done. "Why Peter, why do this to James? To Lily? TO HARRY?! Why?!" The man didn't answer, but simply drew a knife. Sirius backed away slightly before he realised it wasn't a wand. But it was too late… Peter had let out an excruciating yell and thrown his discarded finger to the grubby pavement. He transformed into a dingy, grey mouse and fled to the sewers before Sirius could even contemplate what happened.

Present Time

"Get out of here Remus! Now, go!" James shouted, aware that the time was near to flee.

"No. I won't leave you!" Remus retorted. "We're in this to the end of the line Prongs, together, always." The second crack in a minute was heard, but this time, it was a curse, aimed at the Potter's last magical shield. It shattered under the crushing power of the spell that Voldemort had cast. The door wasn't unlocked gently but blasted off its hinges that now lay so broken on the woollen rug, across the dining room floor. The wooden slab hit Remus square in the chest and he was thrust into the wall behind him, with blood gently seeping from the wound on his temple. James managed to deflect a strong Depulso but was instead met with an intense barrage of curses and hexes. Using well timed protective spells, James managed to get closer to the Dark Wizard to try to initiate an unforgivable, even if it was forbidden. He failed and got knocked off his feet by a burst of magic and was knocked unconscious.

The Dark Wizard made his way slowly up the stairs and came to the landing. A dim glow was emanating from a room down the hallway so he followed it. He found his 'equal', the child, cradled in his mother's arms and weeping like the infant he was. "You can't take Harry! You won't, I won't allow it!" Lily screamed at Voldemort. "Get out of the way, you stupid girl" He shouted, almost as if he was using the sonorous charm. He spoke the words, Avada Kedavra, but the jet of green light was stopped.

Lily had also screamed a spell at the top of her lungs and had said "CAELESTIS SCANDALUM!". The Heavenly Shield Charm. But it mingled with something. A light blue glow was enveloping young Harry and the Shield had turned red. His love for his family had protected him and his mother. The curse had rebounded off Harry and Lily's shield, but not without a cost. A scar had been left on Harry's forehead, in the distinct shape of a lightning bolt. James carried Remus on his shoulder, up the stairs just in time to see all this happen. They watched on in awe and when the last vapour of black smoke disappeared, he knew that the Dark Lord was gone.
