For the time being this is going to be a single chapter one-shot. I am going to devote most of my time to writing my other fanfic, Harry Potter The Serpent King. If Black Hearts gets enough favorites and followers I will eventually turn it into a fully fledged story.
Chapter One. Death's Brother
Narcissa Malfoy went about her work preparing the ritual chamber of the ancient and long forgotten Black Family Residency, Ravenhollow in Southern Wales in silence. As she worked tracing black magic runes over the bodies of the most unlikely couple in wizarding history, she couldn't help her silent sobbing as she thought over the events that had happened just a few scant hours ago.
~~ Riddle Manor 4 hours earlier ~~
Voldemort contemplated the offer made by the young man in front of him for a few minutes before reaching a decision. A cold, cruel smile crossed the snake like visage of the Dark Lord as he raised his wand, leveling it in the face of the Wizarding worlds supposed savior. In a move that shocked many of his loyal Death Eaters present to witness this moment he intoned "Avada Kedavra." As the boy who lived fell dead to the floor at his feet, the Dark Lord briefly considered the boys face as he died. Rather than fear the Dark Lord saw acceptance in the boys eyes.
Turning his fiendish grin upon Bellatrix Voldemort didn't fail to notice the tears that ran down her face.
"Bellatrix my dear" he began in his high cold voice.
"You know the penalty for treason. Luckily you've caught me in a merciful mood."
Without waiting for a reaction the Dark Lord leveled his wand at her and again intoned "Avada Kedavra."
Such a shame to have had to kill her he thought. Bellatrix had been his most loyal, his most deadly, and his most devoted follower. But then she had to bring him the potter brat with the idea she could turn him to the Dark Lords cause. If it had been months ago he may have taken that chance, but after the boys admittedly powerful display against him in the department of mysteries. Voldemort wasn't about to take that chance, he didn't want someone left running around who could one day match him in power. Even if they were on his side.
Voldemort had also found something that disturbed and disappointed him greatly when he bypassed Bellatrix's Occulumancy shields. She'd grown feelings for the boy and it sickened Voldemort to see them.
Snapping out of his thoughts he turned to Narcissa,
"You will dispose of the bodies. See to it that it's done immidiately."
Narcissa choked back a reply, instead she merely nodded. Voldemort again smiled cruelly as he addressed his remaining followers.
"You all know what you must do." Eighteen heads nodded.
"Good now get out of my sight!" The Dark Lord hissed at them.
~~ Ravenhollow, midnight ~~
Narcissa finally finished tracing the runes onto the bodies of Harry and Bellatrix, she didn't like that she had decided to go through with a necromantic ritual. Yet Narcissa was determined to have her revenge on the Dark Lord for the murder of her sister and the boy. This ritual was her one and only chance. She knew the Dark Lord was capable of terrible things and wouldn't hesitate to torture his death eaters as punishment for their failures. Narcissa had never thought that he would kill his own followers.
Narcissa took a deep breath as she went over her last minute checks. Every rune was drawn perfectly over Harry and Bellatrix's bodies. They were correctly positioned on separate alters 5 feet apart. A pentagram was drawn on the stone floor between the alters, five candles surrounding it. The grate in the ceiling was now open to allow moonlight to enter the ritual chamber. Narcissa took one more deep breath, raised her wand and began the incantation.
"Nigrum corda, animarum niger, nigrum ut nocte ut frigida mors. Per immortales lunam per aeterna Opacare. Sapientia enim vocationem et necavit denuo vivere. Rursus Surge!"
As Narcissa finished the incantation an ominous dark purple glow manifested around the two bodies upon the alters. The glow around the bodies suddenly intensified, pulsing like a heartbeat.
As Narcissa watched the pulsing dark glow she noticed the runes begin to activate each glowing a bright red within the purple glow, smiling wickedly she knew the ritual was working. A powerful spiraling current of wind picked up within the ritual chamber lifting Harry and Bellatrix' bodies off of their respective alters, over the otherworldly howling of the wind Narcissa shrieked with hysterical laughter. The Dark Lord had murdered her sister but she would have her revenge.
Narcissa continued watching gleefully as the pulsing sped up and the wind intensified further. Harry and Bellatrix' bodies suddenly dropped back onto the alters and a loud crack like lightning striking metal was heard over the magical maelstrom as their backs arched high off of the stone alters. Suddenly the maelstrom dissipated and within moments Harry and Bellatrix' chests rose and fell as they unconsciously began breathing.
Narcissa took note of the physical changes in their bodies. Their skin was now a dark ashen gray color though otherwise flawless, though there faces looked hollow. When they opened their eyes, they were entirely white, no pupils no iris. Harry seemed to have gotten taller and developed muscle, while Bellatrix seemed to have de-aged somewhat. Harry's famous lightning bolt scar now looked as if it was charred black. Bellatrix no longer had the dark mark on her left forearm, in its place was a 3 inch long, black lightning bolt.
Narcissa grinned savegly in triumph, retribution wasn't long in coming drying her eyes she left the ritual chamber to begin preparations for her revenge spree. After all Voldemort wasn't her only target.
After Narcissa had left the chamber Bellatrix and Harry awoke. The two revenants slowly slid off of the alters and stood up facing one another. Not thinking about their current state of undress they walked towards each other and embraced.
"Bella..." Harry began in a voice as cold as the grave, "Til death do we part..."
"Til we return..." Bellatrix continued in an equally cold voice.
"To seek our revenge" The couple spoke as one.
