Death looked down at the sleeping form in front of her and sighed. There was so much potential here that would never be realized. Sometimes she really hated her job. Reaching down, she gently brushed Lily Potter's hair out of her face. Lily opened her eyes and looked into the face of death. Now contrary to popular believe, Death was a beautiful girl, not some ugly skeleton Grim Reaper. Lily's eyes widened, "It's my time to die, isn't it."
"Yes, young one. It is", replied Death gently.
Lily's eyes filled with tears, "What about Harry? And James?"
Death sighed, "James will die as well", here Lily gasped. "But Harry will live; that is my promise."
Lily's eyes closed, "At least Harry survives." Then her eyes snapped open. "If I assume right and Voldemort is the one who kills us, then why are you here now?"
Death smiled, "Because once approximately every 1,000 years I take the place of one mortal for a day. This allows me to directly interact with the mortal world. I chose you because if I didn't, than Harry won't survive the night and because he is a Ta'veren, or the focal point of the weaves of fate, it is critical that he survives. Otherwise, the world will be thrown into millennia of darkness. Harry is going to be the most powerful wizard of this age."
Lily smiled, closed her eyes, and opened her arms, careful not to hit James, "Then I go to death willingly with the knowledge that Harry will be great."
Death's eyes sparkled as she reached down and gently grabbed Lily's soul and released it from her body. Then Death leaned over and fell into the empty shell of Lily Potter.
Lily moved through the wall into Harry's room and looked down at him. He was sleeping peacefully with his thumb in his mouth. She chuckled at how cute he looked. Leaning over, she gently kissed Harry's forehead, "Goodbye Harry. Momma loves you more that Life itself." And with that, Lily departed into the afterlife.
"Lily, it's Him! Grab Harry and run! I'll hold Him off!"
Death ran upstairs to Harry's room and set Harry down in his crib. He stood up and grabbed the crib, giggling. Tears streamed down Lily Potter's face. "Hold still Harry."
Death pulled out a demonic silver dagger with blood platinum inset runes. She bent down and carved the All Seeing Eye of Horus around Harry's right eye. Then she kissed it while powering her considerable power into it and Harry. The glyph glowed briefly as it was activated, then the cuts healed over until it disappeared completely. Then Death carved the sowilo rune into Harry's forehead. "Momma loves you Harry. I'll always love you." And with that Death turned around, Lily's wand out. She didn't have to wait long.
With a bang, the door burst open and Voldemort stepped into the room. "Ah, Lily Potter. Your husband put up a good fight, but in the end, he was a weakling. You can either stand aside and join me, or I will kill you."
Lily's face contorted with rage, "Never!" she shouted.
Voldemort's voice got cold and quiet, "Very well. Stand aside you silly girl, stand aside."
Lily threw a cutting curse at Voldemort. Laughing, Voldemort batted the spell aside, "Avada Kedavra."
Lily didn't have time to doge, she was hit straight in the chest. She collapsed to the floor, meanwhile, Death left the body and stood in front of Harry. Slowly, Voldemort walked over to Harry and looked into his emerald green eyes. Voldemort pointed his wand in-between Harry's eyes. "Goodbye Harry Potter. Avada Kedavra!"
As the curse left Voldemort's wand, Death pressed a finger to the sowilo and powered as much power as she dared into the rune. Suddenly, a silver aura burst from Harry's body and blocked the curse. As the curse and aura fought, the Eye of Horus burst into being where Death had carved it. It was glowing a vivid violate light. The curse fought against the aura for a moment, then turned back and raced toward Voldemort. Voldemort was so surprised, that he never had a chance and his own curse hit him. Voldemort screamed as his own magic was forced back on him, the power he put into it now shredding his defenses and shoving his soul out of his body. As a last act, Voldemort's magic exploded and blew the roof clean off. The explosion of magic also started the wooden floor on fire.
Unnoticed in all the commotion, a small pure black thing flitted across the room and into Harry's scar. Harry screamed and Death whipped around just in time to see a part of Voldemort's soul enter Harry's scar. Death put a finger back on the sowilo and was disconcerted to find that the piece of Voldemort's soul was trying to take over Harry's body. Death quickly isolated Voldemort's soul and crushed it. But she did collect the memories that existed in Voldemort's soul and implanted them in Harry's subconscious behind a very strong barrier. All of the magic running through Harry had taken its toll. As soon as Death had finished working on Harry, he collapsed into a very deep sleep, the Eye of Horus fading into nothingness.
Dumbledore rushed into the nursery to find the room on fire and Voldemort's cloak crumpled on the ground with Lily's body collapsed in front of a sleeping Harry. Swiftly walking over to Harry's body, Dumbledore noticed the lightning bolt shaped scar on Harry's forehead. Dumbledore smiled as a line from the prophecy came back to him, '…and the Dark Lord will mark him as his equal…'
"So this is the Child of the Prophecy", murmured Dumbledore. Then Dumbledore waved his wand over Harry several times. A frown crept across Dumbledore's face as the readings came back to him. Harry currently had the largest core he had ever seen in an infant. Again Dumbledore raised his wand and began casting spell after spell at Harry.
Dumbledore's mouth twisted into a vicious grin as Harry's magical core shrank until it was just a little bit smaller than an average wizard's core. Placing Harry back into the crib, Dumbledore walked out of the burning room to ask Hagrid to drop by the Potter's house.
After Dumbledore left the house, Death became visible and ripped the spells off of Harry's magical core and pulled a pure black crystal out of a pocket of her robe. She reached in and placed it into the center of Harry's core. This would throw of any mortals readings to believe that Harry had a smaller than average core. Death gently ran her fingers through Harry's hair and waited for Hagrid to show up and take Harry away from the burning building.
