The half-sister of the chosen one
The night was dark and a full moon hung sadly in the sky. One lone figure stood outside that house in Godrics hallow. The house in ruins, still recognizable and bent out of shape. The man, hesitant at first, rushed at the door hanging off its hinges. Stepping into the house he pulled out a long slender wand and brought light to its tip. Everything was in disarray. Many objects lie scattered and broken across the floor. Glancing about the room he shuddered with apprehension. Moving forward he passed the man he'd hated for so long, lying on his back staring wide eyed and lifelessly into the empty space above his head. He felt a twinge of grief, no matter how much he'd hated James Potter he couldn't wish death on him. He continued through the house looking for where she might be. He clutched desperately at the hope that the dark lord would spare her as he said. She had to be there…had to be alive.
Dread filled his soul as he came to the last room. 'This must be her son's room' he thought. The door was in shambles, blasted away. He pinched his eyes shut, stepping into the room. He opened his eyes and ice clawed at his heart and tears fell from his eyes. A quiet whimpering filled his ears but he couldn't do anything but fall to the ground.
"NO!" he wept and crawled forward to the body lying on the ground. He gathered the love of his life into his arms and sobbed more than he'd ever had before. "Not you…not you…" he gasped for air and continued to sob. "Lily…Lily…Lil..." Still holding her his sobbing calmed down to a soft shudder and he looked up at the crib where the other whimpering was coming from. Her son, Harry Potter was alive! He saw the saw the lightning scar etched into his forehead, but the thing that caught his attention the most was his eyes. His green eyes. Her eyes…he has her eyes. He looked away and shut his eyes…and wondered. He could take the child and raise him. He owed her that…but Dumbledore did not want Harry to be raised in the wizard world. He wanted him to grow up normal…and unfortunately among muggles. The sleeve of his black robes had been pushed up and he stared at the twisting snake mark on his arm. It was dull and pale…not the deep, dark, black that it had been before. He breathed a sigh of relief among his still present tears. Free from the evil. The dark lord must be dead.
An eerie note hung on the air and a powerful breeze opened the windows. Gently the man lay lily on the ground and went to shut out the night, but something stopped him. A silver mist drifted into the middle of the room and condensed and swirled in one spot. He paused and stared at the curious event happening in front of him.
A voice drifted quietly and softly to him. "Severus...Severus Snape?"
He blinked at the sound of his name. "Who are you?"
The mist solidified into a young silver girl hovering just slightly above the ground. Snape was slightly baffled and didn't move away as she reached towards him and brushed away a tear. "I am Lunabella. I am of those who control the night. I am of those who wander with the moonlight." she turned and gazed upon the lifeless form of Lily Potter. "You love her" she turned back to face him giving a weak sympathetic smile. "Even with powers such as mine I cannot call her back for the beyond. I can speak with the recently new souls. She wanted me to tell you she has forgiven you…and to apologize for not telling you before. She loves you. She'll be with you always."
Snape wiped away some new tears and stared down at Lily. "Thank you" he whispered.
Lunabella looked at him for a moment and then said…"She says that she knows things could have been different…her choices changed everything. It could have been you instead of James…and she wishes me to give you a gift. In honor of what could have been" she paused a moment. "Take her hand"
Snape knelt to the ground and held lily's hand with both of his. Lunabella placed her hand on theirs and hummed a bittersweet and beautiful melody. The wind seemed to shift and gather in one spot right next to Harry. It swirled and twirled and sparked until condensing into something nearly impossible. He had to remind himself not to let his jaw drop like an idiot. A baby girl sat staring back at him with lovely green eyes. He stared back her in awe "who is she?"
"She is yours. Yours and Lily's. The child you could have had. I have made her real. Her birthday is Halloween. Today. She is a one year old. As she would have been if Lily had made different decisions."
"I have a daughter…Lily's daughter is mine…" he couldn't believe this gift. He stood and lifted the girl from the crib and held her close.
"She'll be different from other children. You realize that don't you?"
"How so?" he peered at Lunabella over the top of his baby girls head.
She gently brushed her hair across the girls head and said "she will be very powerful. Children of this birth bear the sign of the moon." She pushed up the sleeve of the pink jumper the baby was in to show a silver crescent moon on her right shoulder.
He looked down at the mark. "I've never heard of anything like this"
"That is because they are kept a secret. There are few who do know of these children and some of which would torture them into submission and use their powers for evil. Protect her Severus. Keep her secret. Keep her safe. " and with that she vanished into thin air.
