DISCLAIMER: I do not, in any way, own Harry Potter. Everything except my OCs belongs to the amazing J.K. Rowling and Rick Riordan.
Summary: Lily and James are alive. Harry has a twin (this is a wrong-boy/girl-who-lived fanfic). Kyra Black is the daughter of Sirius Black and Ariana Mageia, who "died" when Voldemort attacked. Kyra is the real Girl-Who-Lived. She is also a demigod, and a unique on at that. Read to find out more.
The Attack
A slender, pale hand snaked out of the folds of the black cloak, pulling the hood down to reveal gleaming snakelike red eyes adorning a chalky white face, evil shining from the depths of scarlet. He watched the woman, a slim, black-haired, and unnatural blue-eyed lady, play with the three children. Her laughter rang out like the tinkling of bells. Voldemort smirked. Soon they would be begging him for their pitiful lives to be spared.
He opened the gate silently with a swish of his wand, his feet gliding soundlessly on the leaf-covered floor. "Alohomora," he whispered, pointing his wand at the door. The woman inside began to take the children up to bed. He stepped in, savoring the taste of innocence, craving to bring that happiness to ruins. He sneered at a picture of the carefree family. Filthy blood-traitors and mudbloods.
Not being one to waste time, he began to walk up the stairs, the wood creaking slightly. Reaching the second bedroom, he peered inside the room through the gap. The woman placing a soft kiss daughter's forehead lovingly. He pushed open the door, and she whirled around, her wand out in flash. "Voldemort," she snarled.
"Ah, Ariana Maegia. It's a pleasure to finally meet you," he drawled.
"It's Black now," she hissed. He suddenly shot a curse at her. She dodged it gracefully, sending a curse back in response. They dueled furiously, dodging and shooting. One of the Potter twins started to cry, his hazel eyes tearing up. Ariana glanced at him in concern, and Voldemort used her momentary distraction to his advantage. A green light hit her chest, and she dropped to the ground lifelessly, her ebony hair billowing out behind her as she fell, her bronze skin illuminated by the light.
Voldemort stepped over her body, advancing to the three children. The girl, Black's daughter stared at him unblinkingly with her dark, midnight blue eyes. The other Potter twin, the one with emerald green eyes, gazed at him as if expecting Ariana to suddenly pop back up and hug him while she laughed. The hazel eyed boy continued to wail uncontrollably.
"Kyra, Harry, and Tristan. How enchanting," Voldemort leered. "Which one of you should I kill first?" Tristan cried harder, his chubby hands shaking. He decided on the girl. Pointing his wand at her, he shouted the dreaded incantation, "Avada Kedavra!" Before the curse could hit Kyra, a glowing, blue, bubble-like shield. Kyra's eyes radiated with power as the curse bounced off of the shield and went zooming back at Voldemort. "NO!" And with that, the Dark Lord disappeared, vanquished.
