Chapter 1

September 1st

"Serena! Serena! Get up! You know what day it is, don't you?" Groaning, Serena lifted a hand to her eyes to shade them from the bright sun coming though the windows, uncovered of velvet curtains. Rolling over, she winced, feeling her muscles cramp up, sore from Quidditch practice with Madison the day before.

Quidditch to her was beautiful. It was truly beautiful. An art. Flying through the air on a broom, to take wherever you wanted to go, with no worries, was simply wonderful. A game was exhilarating. Serena had been playing the game and flying since the age of three with her sister when their mother decided the wind wouldn't knock her two daughters of the brooms. Madison had started at five because of the flu that almost killed her when she was a toddler. Nevertheless, Serena was grateful that they both started at the same time.

Her sister began jumping on her bed and Serena growled, all stiffness and soreness forgotten as she yelled, "Madison! Get off the bloody bed!" Serena heard her sister burst into giggles trying to pull covers off her very warm sister. The latter rolled her eyes, let the bedspread go, and grabbed her wand, which she'd had since the age of six, from the bedside table. Pointing it at Madison, she smiled, showing pearly white teeth. "Teddy, be a dear and get off the bloody bed before I hex you into oblivion with one of the spells Ostaris taught us." Madison twirled her phoenix feather, Redwood, thirteen-inch wand with nimble fingers and smiled at her sister. "Too bad I know all the counters."

They laughed together, the knowledge that they could both hurt each other horribly hanging in their minds. Their older brother Ostaris had made sure that by the age of seven, both could send an older peon to St. Mungo's. Madison had been a bit particular about some of the jinxes and curses, but Serena had drunk up the knowledge.

The lessons had shown how different and yet alike the sisters were. Madison was light, always helping, happy, not caring the least what others thought, a carefree spirit. Serena, on the other hand, was dark and cunning, devious, full of ambition. She was often a step ahead of others, and could make herself unreadable emotionally. Madison was white and pure, Serena black and sinister. And yet, around each other and their brother, they both had affection for each other that banished all differences they had, though they also had a small piece of each other in them. Serena had a part of Madison's loving nature that rarely came out, and Madison's sly ability to get out of trouble when necessary was the gray in both of them.

"Well then come on, hurry up! You don't want to miss the first day, believe me. It's loads of fun. Too bad I can't introduce you to people and stuff." Madison's face fell, and Serena stood up from bed, careful not to let her sister see the sad smile that crossed her face. She opened a door the far right of her bed and walked inside, rummaging through rows of robes and shelves full of shoes, finally choosing some and coming back into the room. Stopping to open the window, she smiled and inhaled deeply. Rain was falling in silvery sheets and gusts of cold wind were blowing. It was sheer bliss for Serena. Leaving the window open, she walked over to her sister who had taken up residence on her bed.

"It's all right. I mean, at least you're where you belong. You have friends there and everything." Serena donned a dark blue robe and combed her hair into a braid that reached her mid-back. Rubbing sleep from her eyes, she yawned and looked at herself in the bureau's mirror. Shaking her head, she applied midnight blue to her eyes and grinned in triumph. "Good thing you changed your name before going too, huh? I told you Ostaris was right." Pulling on white socks, she searched under her massive bed for her boots. "Oh, but it'll be great fun. Acting like we're going to be at each other's throats!"

Madison laughed. "Yeah, I can't wait. Though I wonder what Ostaris will say when he finds out the little game we're playing. I mean, he is Head Boy. D'you think he'd take points off our houses? I've tried to avoid him in the halls with other Slytherins, but with you it'll be a totally different game." She put on a pensive face and tapped her fingers together, looking around.

Serena held up her boots triumphantly and began to buckle them up. "I don't know. He might. After all, Slytherin and Gryffindor are worst enemies. It'd be pretty weird if he didn't. He's Slytherin himself. See, why'd you have to get and get yourself stuck in Gryffindor, huh?"

Madison shrugged a smile on her face and stood, heading for the door, Serena right behind her. "Well, let's just hope you get into Slytherin, though I don't think there's a doubt about that. You and Ostaris are alike. I remember he said something about your fetal scans all came back with readings of 'Completely Evil'. I mean, Mum and dad were so proud, gloating and showing off."

Serena smacked her sister on the back of the head and then they both burst out laughing.

Madison tucked a stray lock of hair behind her ear as they descended the stairs. Leaning over the railing, she saw Ostaris waiting for them at the foot of the staircase. "Madison, Serena." After a brief exchange of looks and nods, they straightened themselves up and entered the dining room. They were all excited because of the fact they were soon going to Hogwarts, and yet, the gloomy air around them portrayed their hidden feelings of depression for their departure from home.

Serena took in the grand, long table for thirty, but only set for five and smiled. Today was going to be the last day before Yule that she would sit among her whole family, eating merry and together. The red chairs with their ever so straight backs were dustless, and dim lighting came from the many candles hovering over the table that Ostaris had charmed after coming back from Hogwarts his first year. Their grand view of their grounds was spread out before them through the window, and she smiled again, loving the wet chilly air from the rain.

Madison waited for one of the house elves to pull out her chair and sat down. She looked around sadly, missing the place she called home immediately. Madison never thought she'd get over the feeling of loss every time she left for Hogwarts, but then again, she felt the same way about her school. Reaching down under the table before her parents appeared, she gave Sakura, her black kitten, a scratch behind the ears and smiled when she heard her purr. Looking under the table, Madison laughed to see her sister doing the same with an identical kitten. The two kittens had been born five months ago to their cat Whiskers. Now, Sakura and Shadow were old enough to be taken to school, and going to school they were. The kittens would be something to remember their family and home with.

Ostaris waited until both his sisters had been sitting and then mimicked them. Sighing, he worried for Serena's first year and Madison's third. Looking around, he saw his mother and father come into the room. Riovilio was the perfect image of a pureblooded wizard. His long black ebony locks were held back by a silver clasp, and looked to be made of silk rather than hair. Dark, black eyes shifted effortlessly and seemed to take in everything around him. His pale, full face had no mark or blemish on it except for a small tattoo of the Infinity Rune under his right eye. Satin robes adorned his well-toned figure, and dragonhide boots made soft clicks on the floor as he walked into the dining room.

Lorelai Crow was linked arm-in-arm with him, smiling softly. Lorelai was Narcissa Malfoy's cousin. She was tall and fair, elegant and poised. Long tresses the color of dark honey, identical to Madison's. Bright azure eyes that matched her robe looked tenderly on, and an identical tattoo like father's, graced the skin below her left eye. Infinity. Ostaris watched them sit down, father at the head of the table, and mother to his right. It was oddly mystifying how two people who were so different could love each other so much.

What's more, the way they were had affected their children as well. Madison was loving and kind, having grown up with more company from their mother, who like her daughter had been a pureblooded Gryffindor. Serena had grown in the presence of her father and her Slytherin ways and thinking were beginning to show through. Ostaris himself had spent equal time with both of his parents, being the first, and having had his father around more than the other two before the war had officially started, when their father worked at the ministry as a spy. His mother had taken him when his father wasn't there, and had taught him about life, love, nature, the things around, and other stuff that was the opposite of his father's teachings about ambition, the world, death…

Everyone seated, they exchanged the regular talks of the morning table, and then, their father put his fork down, wiped his mouth with his napkin, and waited for every person to become quiet. When he had everyone's attention, Riovilio started to speak to his heirs.

"Serena, it is your first day at Hogwarts. Make me proud. I expect everything your mother, your tutors, and I to shine through in your teachings. You come from a family of great respect. Madison, continue at the head of your year. I expect no less from you. 'Tis no matter what house you are in. Family is more important than petty school rivalries and we hope for you the best this year. Ostaris, it is your last year at Hogwarts, and we anticipate no less than six out of seven NEWTs. I know how much you want that job at Gringotts, and I shall wish you the best when you get it. Not if, but when. My children, I have great expectations for each of you, no matter how different or similar you are. Show the world our family loyalty. The way we are devoted to each other."

Smiling slightly, Ostaris felt slightly cold inside. The last lines were meant for him and Serena, not Madison, as she was enrolled under a different name. It was a real pity that not only the students, but also the staff had no idea of her lineage. She would always be Madison Lorelei Shugotenshi to them. A girl with no connection whatsoever to Serena Adelina Crow and Ostaris Loki Crow.

Madison gave one last hug and kiss on the cheek to Serena, and her younger sister returned them. "I'm gonna miss you, you nasty little bugger." Serena rolled her eyes and stuck out her tongue. Ostaris laughed at them both, and signaled to the ever so familiar, seemingly brick wall. Madison waved to them both and walked through the barrier pushing her trolley calmly and not as if she were about to crash. But Serena had been to Platform 9 ¾ fourteen total times in her life, waiting for the moment when she was the one to actually have something to wait for on the other side, and knew she was not to crash. Jerking her out of her thoughts, Ostaris linked arms with her and they pushed their trolleys forward.

Upon reaching the other side, Ostaris walked over to a group of what seemed like the whole of Slytherin house, and greeted old friends, some of which had younger brothers or sisters next to them. "Serena, this is Dante Gregor, Judith Star, Raithos Bikanel, Hermes, Faith-" Serena just nodded at each of them in turn after that. She stored names of importance in her mind and then excused herself to walk around the platform.

Going over to her mother, Serena gave her one last hug and kiss and then just walked around, grateful for the slight sprinkling of rain. Feeling drenched to the bone, she relished in the cold. Laughing, she looked up at the sky, wishing the rain would never end. Someone covered her up with a long, black, heavy coat. "You'll catch a horrid cold if you don't stay warm. And believe me; you won't want to miss your first day at Hogwarts for anything. Serena turned instantly, surprised. A Slytherin with way black hair and the crest of a third year had followed her. She recognized him as Raithos Bikanel. "Hey." He put his hands in his robe pockets and hung his head. She grinned. "Hey." Looking up and then down again, Raithos seemed ponderous for a moment before looking back at her. "Um, want me to show you around?" Serena smiled at him, and nodded. "Sure."

Ostaris shook his head at the sight before him, snickering. Raithos had turned bright pink when Ostaris had introduced him to Serena. But he wasn't worried. Ostaris had him under his thumb, the troublemaker. Raithos was a difficult character to figure out, but had a good mind. He knew not to do anything stupid. "Now, where's Madison?"

Madison shook her head as she saw Priscilla, one of her friends try and not succeed at turning her hair a bright shade of red. Everyone else in the compartment laughed when Priscilla realized that the spell had backfired and made her own hair turn a nasty puke green. "Ugh!" A different voice that rang with laughter made her look up. "Timais!" A head full of brown, short, curly hair looked up. "Madison!" The third year came forward, arms outstretched in a ready embrace. They hugged fiercely and Timais kissed her cheek. "Remind me never to leave for home unless you're next to me." The whole compartment erupted in laughter again.

Lorelai Genevieve Crow was never joyous to see her two eldest children off to school. It made her smile sadly whenever they had to leave for Hogwarts, yet she always had Serena there. They read and wrote together, something that each of them loved. They had both laughed at certain comedy and cried together at the ending of something sad, and even though Lorelai knew Serena had more of Riovilio in her, she still loved to teach Serena about the one thing that never failed to ignite the spark of interest in her eyes. Life. Lorelai cherished the moments she had with her two eldest children; always knowing that she still had company at home. Now that was going to change as well.

Her husband was standing a way off, chatting with some family friends, and he caught her eye. She smiled, full of confusing emotions as she turned her attention to Ostaris talking to Serena, and Madison with a group of third and fourth year Gryffindors. Madison she had missed the most, though she loved her children each for different reasons. Riovilio departed from his friends and gave Serena one last hug. Walking towards Lorelai, he stepped to her side and she looked up at him and then their children. Riovilio put his arm around her waist, and Lorelai leaned into him. They were both thinking the same thing. How fast their children had grown up.
