This is my first Harry Potter fanfiction. It's an AU. The setting is years after Harry and the gang have graduated Hogwarts. Please review and be nice, no flames. I have a short, short chapter that tells you what has happened before. If you want me to post that than tell me. Also I am having trouble with coming up with a title.

Artemis

I do not own Harry Potter but I do own any characters that are my originals.

The full moon began to rise in the eastern skies. The bloody sky began to turn into a midnight blue. Mars blinked brightly in the heavens while troubled stirred on the earthly ground.

"Now the time has arrived."

"From which it has derived."

"The child knows not what she will become." A giggle erupted.

"Silence! We are not safe."

"We would be, brother, if we began."

"No, not without her."

"She is only fifteen! That's waiting six years."

"We are immortal. We will wait."

The woman, who looked no older than twenty one, grumbled silently.

"Now back to our places. The time is for waiting, not action."

With that five figures disappeared into the black night.

Illyria Potter sat on the edge of the tower's side. Slytherin's Tower was her refuge. She often came up there after dealing with her family. Illyria Potter had a small, skinny build, perfect for a seeker. Her hair was black and her eyes emerald green. She stretched her muscles with a yawn. The wind blew and revealed the Slytherin crest.

"Miss Potter," A voice drawled behind her, "two weeks detention with me."

Illyria smirked, "But professor there is only week left."

"Potter." The voice ordered her. With a small, sigh Illyria removed herself from the edge and followed her head of house.

"Miss Potter was at the Slytherin Tower, again." Professor Snape snarled again.

Illyria peeked from behind Snape. She could see the teachers relieved. Dumbledore had that annoying twinkle in his eyes. McGonagall pursed her lips in thought. Hermione Weasley looked relieved but angry. "Come on Miss Potter." Professor Snape commanded her as he steered her towards the dungeons. Illyria gave the password and started to enter the Slytherin common room. As she entered she heard Snape call out, "Seven o'clock, Potter." Illyria entered the common room smirking.

The Slytherin common room was not what students of other houses would have thought. The room was very large. Comfy couches and chairs scattered the room. A large collection of books were at the use of Slytherin students, some of them would have been in the restricted section. A few desks were near the collection of books.

"Set off the alarms again, Potter?" A Malfoy's stately voice drifted over to her. Illyria plopped herself in a chair near the other Slytherins in her year. Illyria was the first Potter ever to be in Slytherin and she was quite proud of her cunning house.

"Yup and two weeks detention with Snape." Illyria answered with a grin. Nathaniel Malfoy was the youngest Malfoy child. He had an older brother who was a sixth year. His father was Draco Malfoy, who worked for the Ministry. Michael Goyle, who was not as stupid as his father, was also in their year with Jacob Crabbe. Sarah Avery was also sitting with them.

"Where are the others?" Illyria asked, noticing the absence of the other classmates. "Studying." Crabbe answered. Illyria watched Malfoy snicker quietly. Before Illyria could say anything more she felt someone rub her head. She glared and growled in annoyance at Lucius Malfoy.

"Father wishes to speak with us, Nathaniel." Lucius stated with a slight warning in his voice. Nathaniel nodded with his face masking his fears. Illyria watched them leave before turning to the fire. She slowly began to drift towards sleep.

Darkness covered the landscape. Illyria looked around disorientated. The last thing Illyria remembered was falling asleep. A low, dark rumbling could be heard in the distance. The rumbling sent a cold chill down her spine. Before she could move, she felt large, cold hands begin to choke her. She tried to pry the hands away but found no solid hands were choking her. Illyria sank to her knees. Her vision started to become cloudy. She tried to escape the hold on her. Illyria continued to gasp for air. She began to fall slowly into the darkness.

Illyria sat up with a gasp. She gulped the precious air. She looked around and found herself alone in the common room. With a sigh of relief, Illyria leaned back in her seat. She rubbed her temples in an attempt to bring reality into focus. Illyria's head jerked up at the sound of someone entering the common room. She relaxed when she realized it was only Professor Snape. Yet when she saw his face, her face fell. His face was in a deep, dark scowl.

"Your parents wish to speak to you in the headmaster's office." Snape told her. Illyria nodded numbly and stood to follow. She absolutely dreaded these conferences.

Illyria barely heard Snape say the password to the headmaster's office. Illyria opened the door to see her parents speaking to Dumbledore and McGonogall. Illyria took a step back to leave, but Snape kept her from leaving. Illyria walked over to a chair and sat down. She leaned back in the seat and put on the mischievous smile that annoyed her parents greatly.

"Illyria Alice Potter! Do you wish to give your parents heart attacks?" Her mother, Ginny Potter, asked exasperated.

"Now let Miss Potter explain." Dumbledore said gently, looking at Illyria. Illyria wished she could turn invisible.

"I was just sitting." Illyria answered simply.

"Just sitting? Illyria, these are dark and dangerous times. You can't go off on your own." Her father, Harry Potter, tried to explain to her. Illyria knew her father was under great pressure due to Voldemort but every little thing she did was wrong. Illyria mumbled something quietly.

"What was that?" Her father asked. Anger flashed in her emerald eyes, "You would let your precious Gryffindors run around!" The room went silent after Illyria's angry outburst. Illyria looked away before continuing, "May I be dismissed? I am being punished for my actions."

"You may go Miss Potter." Dumbledore dismissed her. Illyria left quickly with the door slamming behind her. McGonagall spoke in the silence, "We are losing her."
