A/N- Hi! This is my story Lady of Darkness. Ariadne is Voldemort's daughter. Please do not ask how this is so, because it will be revealed piece by piece through dreams, unlocked memories of her mother, and memories. If you have any questions, you can leave a review or PM me.

Disclaimer- I admit that I do not own the characters you are familiar with, but I do own Ariadne's... characteristics and her mother, whose name is not yet to be revealed.

I ghosted through the halls of the Malfoy Mansion, going towards the meeting room. I saw a few Death eaters that were not invited cower under my scowl; they knew what I could do when I got mad. I threw the closed doors to the room open to see the favorite death eaters seated around a long table. I may have only been fourteen, but every person knew what I could do.

"Hello, Ariadne," my father told me. I gave a cold smile, which was more of a smirk, and took my place beside him. "Did you sleep well?"

"As well as possible when there was a screaming man next door. I nearly got out of bed to kill him myself."

"I am sorry, my daughter. Would you like to be the one to question him later?" he asked maliciously. I nodded and showed my smirk again.

"We shall get started..." The meeting went on for almost an hour before we were dismissed. I stayed behind with Severus and my father. "Severus, how are things with Harry Potter?"

"Well, my Lord," Severus told him, the only one, besides me, who would not stutter while talking to my father. He was, of course, the scariest man in the wizarding world.

"Good. He is nearing his fourth year, correct?" Voldemort asked.

"Yes, my Lord."

My father smirked at the potions' master. "Thank you, Severus. You may leave; I need to have a word with my daughter." Severus left, leaving my father and I to the large room.

"Ariadne, I need to ask a favor of you..." I knew that this conversation would end with me doing something he knew I would not like when he said those words and stood up to pace the room. "I need you to go to Hogwarts to be a spy among the students."

I froze in my seat; I narrowed my eyes and looked at Voldemort. "You want me to go to Hogwarts!" I yelled, my voice getting shriller with each word. My father winced at the last word and nodded. If he was the scariest wizard, then I was the scariest witch.

"I need another spy there and it would be best if it was someone who could keep an eye on Potter. You are the best for the job, as you are the age of the year he is. Would you be willing to do this?" he asked. I clenched my teeth and pulled out my wand, feeling the need to destroy something.

"I will think about it. Right now, I have the urge to kill something," I growled. Voldemort smiled at me and told me that three of the lower ranking death eaters had tried to expose the hiding place of our headquarters and that he needed them killed.

I stormed out of the hall, thoughts of Hogwarts swarming in my mind, and to the room where I knew all the death eaters would be gathered. They must have heard my shoes hitting the floor angrily because the doors swung open before I reached them.

"Snideman! Radcliffe! Powell!" I screamed. The three men were pushed forward and onto their knees. "I have heard from my father that you three tried to expose this place. Now, I don't believe that all three of you would be stupid enough to do such a thing, I am going to figure out who tried to expose us and who's lying." I said all this in a fake voice, my smirk appearing on my face.

"M-m-m-my L-l-lady, p-p-p-please w-we-" I cut Powell off with the Cruciatis curse and he fell on his stomach screaming. Other death eaters flinched, knowing that I had a just as strong, if not stronger, torture curse than Voldemort himself.

"Do NOT lie to ME!" I shrieked at them. I knew that they would never even think of lying to me, but I needed to kill someone and I needed to have some fun with it. I released him from the curse and he gasped for breath. I was smiling at him, even if it was fake.

"Now, which one of you is guilty?" None of them replied. I sighed and tilted my head. "Fine; more fun for me then."

"AVADA KEDAVRA!" I pointed my wand at them and all three fell completely to the floor, dead.

All the other death eaters cringed and moved back to their original places after bowing to me. I turned and left their room and headed to my quarters; but instead of walking into my own room, I went to the one on the left. The one that held the screaming man that had kept me up all night.

I opened the door and walked inside; I saw the man lying against the back wall, trying to claw his way out. "I would not do such a thing if I were you, Grint," I hissed. He froze and turned to face me.

"M-m-m'lady, I-I-I-I." He stopped speaking and began screaming.

"Listen to me, Grint, we need information and you are going to give it to us or die! Choose one!" I yelled at him while performing the Cruciatis. After a minute or so of my fun, I released him from the pain. In my fourteen years, I had never experienced my own spell.

An hour and many, many curses later, I asked him the same question. "I will ask you one final time before I either kill you or keep you under that spell for an hour. Do you work for Dumbledore or the Ministry?"

Again, the man was stupid, so again, I kept a promise. "AVADA KEDAVRA!"

The man fell to the floor on his stomach as Powell had earlier when he was under my Cruciatis, dead.

"Dwaid!" I screamed.

The house elf in question appeared and bowed. "Dwaid is here. What is Mistress Voldemort wanting with Dwaid?" I, surprisingly, held a bit of sympathy for this elf, for he was the one that came to me when I called and he had to learn to pronounce my name. Fortunately, once I went to Hogwarts, I wouldn't have to worry about house elves memorizing me name, for I will be going by Ariadne Riddle, a semi-common last name.

LOTN-LOTN-LOTN-LOTN-LOTN

On August first, I apparated to the train station. I would have normally just found my way to Hogwarts, but I had to keep up appearances, as my father said. He said that he hoped I would either be in Slytherin, to uphold the family's honor, or Gryffindor to get closer to Harry Potter.

I almost hoped to get into Gryffindor just so I would be able to leave Hogwarts faster.

Almost.

I walked through the wall between platforms 9 and 10 and made my way onto the train. Father had already sent my things ahead of me to the school. I found my own compartment since I got there earlier than most children and read a book that I chose to keep with me. I only looked up when there was a knock on the glass door, which I had closed on arrival. "May we join you?" It was a Weasley, as I could tell by the second hand clothes and red hair, a mudblood, as I could tell by the way she did not think of herself as graceful and powerful by the way she stood, and Potter.

I smirked, a natural habit. "Of course." They sat down, the Weasley and mudblood across from me and Potter beside me. I resisted the urge to kill him then and there.

"I'm Ron Weasley. This is Hermione Granger and, well, you know who he is." The Weasley pointed at Potter, who showed his scar.

"Harry Potter. Of course I know who he is. I am Ariadne Riddle. And, may I ask what blood status you are?" It may have sounded wrong of me to ask that now, but I knew that it would help later.

They looked at me strangely but answered. "Well," Potter said, "I'm a pureblood (A/N I now that in the books, it says he's half-blood, but read my bottom author's note for my explanation.), Ron, here, is pureblood, and Hermione is muggle born, but she's the smartest witch in our year." Well, now I am.

"I'm pureblood. I grew up with my dad. My mum died when I was young. My dad went missing for thirteen and a half years. I had been raised by my Aunt Bella, Aunt Cissy, and Uncle Lu up until then." It was true, but I had left off most of their names: Aunt Bellatrix, Aunt Narcissca, and Uncle Lucius.

Potter was sympathetic. "I'm sorry. That sounds a lot like my life. I hope that your aunts and uncle were better than mine."

The rest of the train ride was silent up until they needed to change into their robes. Ron noticed that I didn't have a badge on mine. "Are you new? You don't look like a first year."

I laughed, a rare thing. "That would explain why I'm a fifth year transfer, then."

Once we arrived and were in the foyer, McGonagall led the first years and me inside the Great Hall. I had only seen it in my father's memories and once when we snuck in for an attack, but it was night and I couldn't see much then.

Dumbledork stood up and said that there would be a fifth year transfer student and asked that I be sorted first. I walked up to the stool and McGonagall placed the ratty hat on my head.

"Oh, I never thought I would hear someone call me ratty," the hat said sarcastically.

"Oh, shut it and place me," I thought back.

The hat laughed. "Well, even though your father was in Slytherin, I think that you would do good in either Gryffindor or Slytherin. But, for the sake of your poor, poor head and saving it from that idiot Malfoy..."

"SLYTHERIN!"

I sighed but still did my original smirk; I stepped down and walked over to the Slytherin table where Malfoy made space for me to sit next to him. Since I had lived with him for pretty much my entire life, we were close, as in brother/sister close. He knew that I didn't have any feelings like that for him and he knew that if he acted on any hormones that I would hex him into oblivion. He kissed me on the cheek and I slapped him, hard, on the shoulder. "Don't do that or I will make a new hex just to use on you," I hissed.

Draco chuckled. "Ari, this is Crabbe, Goyle, Blaine, Pansy, and Flint, head of house, is over there." He pointed to each person in turn and I nodded and smirked/smiled at each of them. I looked at Pansy the longest and she seemed to shiver.

During the feast, I learned that the Slytherin chambers were in the dungeons and that Snape preferred the Slytherins and has never taken a point from us. I found that a good thing, since I would most likely have to break many rules to torment Potter. I would have so much fun this year.

When the feast was over, Flint led us to the common room and told the first years and I where everything we needed was and then we were told to go to bed and be up for classes. I went into my dorm and saw that there were four other girls in there. I could tell that only two of them were purebloods. What has this school come to, allowing half-bloods and mudbloods in?

The next morning, I forced myself to wake up before the sun and go down the common room. I pulled out my mirror and called my father on it. He answered quickly. "Hello, daughter. I'm surprised that it took so long for you to call."

I chuckled quietly. "I would have called last night, but my roommates kept me up and then wouldn't fall asleep until I did. They actually have half-bloods and purebloods in the same dorm. And there were at least fifty out of 270 students that are mudbloods. It's a disgrace to mix the non-magicals with us pure magic." I shivered in disgust. "And Potter is friends with one of them. Hermione Granger: smartest witch in this year until the first class today. He's also friends with the blood-traitors, the Weasleys."

Father chuckled. "Slow down a bit, Ari. I do not need all of this information quite yet. Wait for another week and call me again. I'll have something for you to do and I'll expect a full report on everything that has happened. For now, stay on the teachers' good sides, especially the oaf running that school and the deputy headmistress. Tell Severus that you will be doing things for me periodically throughout the year."

I nodded to everything he said before hearing footsteps coming down the stairs from Flint's room. "I must go, Father. Somebody whom I must respect is coming." I nodded a goodbye and he did the same before I hung up and hid the small mirror don my shirt.

Flint came down the stairs in his robe and saw me sitting on the black leather couch. "What're you doing up so bloody early, Riddle? 'Round here, we don't get up until seven fifteen at the latest."

I chuckled. "I'm an early riser. What're you doing up then? I was practically silent." It was true. I could talk so quietly that no one knew that I was even talking unless I spoke directly to them.

He cleared his throat awkwardly. "I guess I wake up early, too," he said quietly.

I laughed again. This was starting to become a habit; I would have to stop laughing so much. "Nothing embarrassing about waking up before everybody else. Whenever I woke up, Draco would still be out like a bloody light and I'd have no one to talk to until nearly nine am or until he decided to rouse his lazy arse."

"Thanks a lot, Riddle. I'll remember that the next time you sleep longer than me and I'll get the chance to pour freezing water on you." Draco, apparently, decided to wake up and come see if I was up. Both the boys stood in the entryways of the stairs to their quarters, shifting uncomfortably. I rolled my eyes and moved to the middle of the couch and patted the seats beside me.

They came over and sat down and I hit Draco again. He rubbed his now sore arm. "Oi! What the bloody hell was that for?" he yelped.

"For being a bloody arse, that's why." I smirked at him. "So, where's the body guards? I know that they're always by you. Didn't they come for Christmas one year?"

He tried to hit me back but I pulled out my wand and pointed it at his face, ready to perform the bat bogey hex or something if he hit me. He scooted to his end of the couch and put his hands in the air. "Joking! Joking!"

After a couple of hours of blabbering on about potions and how this years was supposed to be the best yet, many other students began coming down, fully dressed, and headed out for breakfast. I saw a few little firsties following the older students, not wanting to get lost.

I decided to go back up to my dorm room and get dressed. Once I did, I walked downstairs and out the door to get some breakfast.

Let the day begin.

A/N- How'd you like it? Please review.

The explanation for Harry's being Pureblood: Lily was a muggle-born and James was pureblood. Harry's ancestry is not entirely pureblood, but both of his parents are magical, therefore making Harry a pureblood and not a half-blood. If you want a more detailed explanation, PM me or review and I will answer any questions.

If you have any other questions that I did not specify that I didn't want people to ask, go ahead and ask. If it will be revealed later in the story, then I will tell you so. If it won't, then I will answer. I will also reply to all reviews that are not anonymous.
