Celestial Bodies: A story of Twins

Chapter One: First Impressions

"It's the first day of the school year and you're already in trouble! Could've you have waited a week or two to at least have settled in!" said the agitated voice from the head in the fire. The man's face seemed to release most of its anger and sighed, shake back and forth a bit. "What am I going to do with you little sis." His green eyes, equally as bright as hers, looked over his sister. Her jaw-length black hair on her pale skin, the cocky smirk that pulled at her red lips, and her emerald eyes glinted from the embers, all pulled together in what seemed to be an image of nymph. She stood in the headmaster's office, her slender body covered by the messily worn boy's uniform, which gave off a tomboy look.

"Well maybe if I didn't think that I was going to be transferred with in the first few months I wouldn't act like that." She said with a sort of a growl. Her body language seemed to snap at him.

"Cat, maybe if you didn't pull stunts and pranks on everyone you saw I would have to keep pulling you out of schools!" He replied in the same tone as she had commented in. She glared at him and was about to bark back nastily when a gentle hand rested onto her shoulder, which subsided her instantly.

"Now Miss Marin, there's no reason to fight, even if it's in your nature." said Headmaster Dumbledore in his wise way. The headmaster raised his hand from her shoulder and moved in front of the fire beside her. "Ah, Mr. Marin, care to stay and chat about your findings at the ministry? I've read up on them but would like the insider's scoop you could say. Young Miss. Marin must be off to class now." He said, his old azure eyes looked to her and he nodded. Cat sighed and looked to her brother.

"Catch you later Luke." She said with a wave of her hand as she turned and walked out of the magical office and walked down the stairs. Catalina walked beside some Gryffindors, already being shunned by most in her house of Ravenclaw. She was on to her advanced potions class for sixth years. It wasn't a required class, and not many people took it but she found it quite interesting.

She broke away from the group and headed toward the dungeons. Cat moved quickly down the shifting staircases and through the corridors and walked into the room at the same time as the platinum haired boy that had entered with her. Professor Snape wasn't pleased; he looked as if he was going to say something but just glared.

"Take your seats you two, there's only one double desk left. I know you won't mind sharing it." He said coolly. The platinum haired boy glared.

"I'm not sitting with her!" He spat, his blue eye as icy and cold as his voice.

"Well, Mr. Malfoy, if you had gotten here sooner, maybe you would've gotten your desired seat." Snape retorted and got up from his desk as he started to begin the class. Cat and Draco walked grudgingly to their seats.

The Ravenclaw slid into her seat with a laidback style, and Draco seemingly did the opposite. They sat there in silence, not speaking through the professor's entire lecture of different drafts and what was in them. Cat lazily sketched on her parchment, occasionally taking notes, and her eyes scanning around the room dully.

"Its group project time. I'm assigning you a potion that you and your partner must complete and complete successfully. You partners are who you sit with now, the right side must make a polyjuice potion, the left side will make wolfs bane potion. You are dismissed." Snape said and turned on heel, his cape flapping, and resided back to his desk.

Cat and Draco groaned at the same time, knowing that the professor did this to spite them. The Ravenclaw got up and slid on her bag, casting a glance to Malfoy. "I'm Catalina Marin; better learn it since I don't respond to ill said names." She said with a bit of a glare. "Where should we meet to get started?" Draco ignored her for a few seconds, making Cat's temper rise and when he was done packing his things, he turned to her.

"Listen, I don't want to work with you, nor be around you and your bloody Gryffindor friends. So we spend one, and I mean one, day on this. If we can't figure out how to make a wolfs bane potion, then we give up." He said through a scowl.

"That would be something, since you can't make a wolfs bane potion in one day, it takes longer to brew it." She sneered back. Both of them seemed to mirror each other, but seemed so opposite. "Show's what you know about potions."

Cat walked out of the door, or tried to when she bumped into Draco trying to walk out as well.

"Watch where you're going!" They said angrily at the same time. She shook off the oddness of that and took a step back. She bowed mockingly. "Ladies first." She said with a grin and shoved Slytherin out the door and strolled out quickly.

Cat sat in the library, her deep gaze looking over the pages slowly of her book. The red leather bound book's title read Rare Happenings and Strange Coincidences by Madam Hesmire. The Ravenclaw flipped through, reading about people being born with two head, or joined at the hip. Her eyes found something to delight their interest. Cat read out loud softly.

"Those born at the same time, with the same start sign and same day, hour, minute and second are say to be bonded by the stars. Such people are a rare thing to find, it happens once or twice a century, and most of the time the two never meet or know of it. There are times when the two bonded ones meet, the seem to feed off each other and become more like each other. Thus being called Celestial Twins, or Star-Fated Bodies." Cat frowned, and closed the book. She took it with her and over to the librarian, Mrs. Prince, and borrowed it out of curiosity.
