There are a couple reasons for this, but I've changed the story from a Harry/Hermione to a Harry/Hermione and Harem. I say both because Hermione will probably be in here a lot more than any other girl, despite Harry having a harem. If people really despise this idea, let me know. If enough people hate it, I might switch it back.

The reason that he was only interested in Hermione earlier will be explained, but not for a while. It'll need to wait for certain characters to enter the story. There are a few possibilities as to who will explain it.

Chapter 2

Nightmare

The ride had been going smoothly when the train suddenly stopped. Hermione felt a chill and held on to Harry. The windows had begun to frost over and Harry felt something at the back of his mind, even as a shadow drifted past the glass.

"Harry, a demon approaches." Ascelon hissed.

"Demon? What demon? Is that what stopped the train?"

"There are many Demons coming. They are Demons of the Mind branch. These particular Demons are known as Nightmare Demons, who go by the name Dementor now."

"A Dementor…"

"What is it?" Hermione asked, shivering.

"Apparently, a group of Dementors are searching the train." Hermione gasped.

"Dementors? But those are the guards of Azkaban… why would they search the Express? This is horrible! They suck the happiness out of everyone they're near."

It was then that the door to the compartment opened and a hooded figure entered. Hermione screamed and clutched at her head. Apparently, Harry was immune to their ability.

"Begone!" Harry ordered. The thing began to turn before it flinched, something around its neck glowing, and continued onward. "Fine then." He raised his right hand, the one with the golden Ouroboros ring on the index finger. Ragnok had said that it could function just like a wand, and he didn't want to reveal his Demonsoul powers. "Stupefy!" He declared. But nothing happened.

"What?" He wondered, confused. But the Dementor was still approaching and Hermione was screaming even louder.

How do I stop it?! Harry panicked. I can't use magic? Fine then. Shadows swirled as he began to activate his powers. However, before he did anything, Ascelon leapt from his outstretched arm, growing until he was ten times his usual size. He wrapped around the cloaked figure and dragged it backward. Then, he sank his fangs into the Demon and, seconds later, nothing was left but an old cloak.

Hermione stopped screaming, but was still shaking, near comatose for some reason. Harry pulled her closer. Ascelon shrank back to normal size and slithered over to Harry.

"It seems that your human magical core no longer exists. You must rely on your new Demon core."

"Demon core?" Harry didn't know anything about having a new magical core.

"Yes. Your transformation granted you a new type of magic that is far more powerful than any amount of human magic. However, you must learn to use Demon spells, rather than those of humans."

"That'll be a pain. What am I supposed to do about class?"

"I am sure that there is no feat that any human can perform that you cannot replicate. You will simply need to tap into your actual powers, until you are able to shape the Demon magic."

"Alright, so basically, you're saying that I can use my powers to simulate the effects of normal spells, until I can perform the Demonic equivalents?"

"Exactly. Now, if you don't mind, I'm going to sleep. I do not have a great deal of energy, since I have not yet reached a certain level of power."

Then, Harry had a thought. "You need to feed to grow stronger, right? How does a thousand-year-old basilisk sound?"

"Delicious. Basilisks are actually lesser mutations of a descendent of the Ouroboros. It will be quite helpful towards regaining my power, as well as accelerating your growth. Thank you, Harry."

"No problem."

As Ascelon curled up around Harry's arm, Harry saw a glint of red on his ring. He raised it up and saw that one of the Ouroboros' eyes had lit up. He was surprised to see three sets of eyes on the tiny snake ring. Ascelon only had two, and he knew that normal Ouroboros' only had two as well, although they could gain more if they desired it. Somehow, he knew that the six eyes were measuring his level of Demonic development. When all six had lit up, he would be able to use his new magic.

Harry shook Hermione's arm. "Are you all right? Hermione!" Her eyes flickered open.

"H-H-Harry? What happened? I saw the Dementor and something just… it was like something inside of me went dark."

"Ascelon." He indicated his arm. "My Ouroboros familiar, in case you don't remember, enlarged, keeping it back, then bit it. The thing is gone. Its cloak is all that's left."

"Good." She said, then she realized something. "But physical attacks shouldn't work on a Dementor! Only something called a Patronus Charm can work."

"I guess that the rule doesn't apply to Ascelon." Harry said with a shrug.

[

Finally, the train came to the correct stop. As they got off, Harry saw a disheveled looking man looking around. Then, the man looked at him and gasped.

"James?" He asked in wonder. "No. Those're Lily's eyes…"

"Who are you?" Harry demanded.

"I'm sorry. You must be Harry. My name is Remus Lupin. I was one of your father's closest friends at Hogwarts. I don't expect that you would remember me, but, around you, but your father only referred to me as 'Uncle Moony'" He said with a chuckle.

"Wait a sec…" Harry thought for a second. "That's right! I remember hearing that before!"

"What?" Hermione asked, interested. "How can you remember something from that long ago?"

Harry shrugged. "My memory's been getting better lately." He reminded her. Her eyes widened.

"Oh, right. But what are you doing here, Mr. Lupin?" Hermione asked.

"I am here as the newest Defense Against the Dark Arts teacher." Lupin explained.

[

Harry was bored out of his mind at the feast, since he didn't need to eat. His hunger couldn't be satiated by food. And speaking of food, he wanted to head down to the Chamber of Secrets. He spent the feast looking at the girls all around him. He'd been surprised to find that he was more… interested in them than he'd ever been before. He watched them as he sat through the rest of the feast and the headmaster's speech. He was surprised and happy to hear that Hagrid was the new Care of Magical Creatures professor. He also wanted to talk to McGonagall about changing his classes. After some magical study over the summer, he had decided that Arithmancy and Runes would be a good idea to take. Being able to calculate spells and use runes would be very helpful skills. Besides, he'd looked at the Divination textbook and, frankly, it looked like bullshit.

After the feast, he went up to talk to McGonagall about changing his classes. She had accepted his decisions, altering his schedule then and there. He'd smiled when he'd seen that he was sharing every class with Hermione. She had decided not to take Divination as well, and she'd changed her mind about Muggle Studies, since it would be an utterly pathetic course. The textbook hadn't barely mentioned computers, let alone the internet. After they'd gotten their schedules and the password to Gryffindor Tower, the two had decided to head to the Chamber of Secrets. Hermione wanted to accompany Harry, since she'd never seen the Chamber.

They'd gotten to Myrtle's bathroom and Harry had been about to open the Chamber entrance when Ascelon had hissed.

"Open for the Heir of Slytherin!"

Instantly, the entrance opened. This time, however, there were stairs that led down into the ancient Chamber. The stairs were completely clean and well lit.

"Wow! I thought you said it was a really grimy slide?" Hermione asked.

"It was." Harry looked at Ascelon. "What did you do?"

"Open the Chamber for you." Ascelon replied drolly.

"But I-"

"Do you really think that Salazar Slytherin slid down that slide to get to his chamber?"

"I guess not."

"Harry?" Hermione asked.

He shook his head. "I've got to find a way to give you Parseltongue. Ascelon was just reminding me what a snob Salazar was."

"Hey! I didn't say that!"

Harry chuckled. "Nah, he just said that Salazar wouldn't have gone down a slide to get to the Chamber."

Hermione laughed. "True. Well, let's go."

[

Harry chuckled as Ascelon quickly devoured the massive snake, growing larger than Slytherin's basilisk had been in order to consume it. Once it was done, Ascelon shrank back down and slithered over to Harry, who could feel the new power in him. Ascelon flew up around Harry's arm.

"Tasty!"

Harry laughed again. "I can't say I ever expected anyone to say that about a basilisk."

Somehow, Ascelon managed to make a snake look affronted. "Obviously you never met anyone like me before."

"You can say that again." Harry laughed. He felt like he was in a constant high, mainly because of all of the death and darkness that were still present in this Chamber. He had been consuming so much of it that he could actually feel his power growing. Two more lights, blue and green, had appeared on his ring. He was halfway there.

"Wow!" Hermione said, walking over to Harry. "You should come see this."

Harry shrugged. "Alright." He followed her into a hidden alcove. Inside was a fantastic library that was filled with equipment as well as hundreds of books. It looked like it was Slytherin's laboratory or private quarters.

"I know!" Hermione said, seeing his amazed expression. "Unfortunately, I can't seem to get in." Even though she was walking into a doorway, it was like she was walking into a wall for all the good it was doing her. "I've never even heard of wards like this before."

"You try, Harry." Ascelon said, having finished his meal. He was much larger now, both in size and magical power. He shrank down back to a size slightly larger than his original size, so that he would still be able to travel around with Harry.

Harry shrugged and tried walking into the lab. He felt a pleasant heat as the wards vanished and he stepped into the lab. Somehow, he instantly knew where everything was. He knew every book in the room and where each was. There was a smaller cupboard where dozens of extremely rare potion ingredients had been stored in stasis. Harry somehow had all of Slytherin's potions knowledge, allowing him to know every single use of the ingredients.

"Incredible." Hermione said as she looked around the room. Apparently, when Harry had entered the room, he'd dispelled the wards. "I've never even heard of any of these books." She looked like she was in paradise.

"Not now." Harry told her, grabbing her shoulder. "We've got to get back to Gryffindor Tower before anyone notices we're gone."

"Fine." Hermione sulked, or tried to. Her eyes had glazed over the moment that Harry had touched her.

The moment Harry exited the room, the wards were back in place, ensuring that Slytherin's lab remained protected.

[

On their way back to the Tower, they'd been accosted by Draco Malfoy and his two goons. "Missed you on the train, Potter." Malfoy said with a sneer.

"Yeah." Harry muttered. "You were too busy cowering in fear to come and bother me."

"What was that?" Draco asked, angry. Potter dared to insult him. It hadn't been the first time, but something seemed different about the Boy-Who-Lived. "How dare you insult me, Potter! I see you've gotten together with the Mudblood. Good for you. One piece of filth deserves another."

Harry didn't lower himself to give the blond boy a verbal response. Instead, he smashed his fingers into the boy's right elbow, completely destroying it. A single strike to the temple had disabled his two idiotic bodyguards. Draco had screamed as he clutched his arm, while Crabbe and Goyle were unconscious on the ground. Harry had simply escorted Hermione around the three boys and led her up to the dorm.

[

They'd made it to bed without incident. However, something had happened not long after midnight. Something had pulled aside his curtains. There were about two-dozen girls in the third-year boys dorm room. Harry recognized them all as being the girls that he'd checked out during the feast. Hermione was the closest, and she was staring at him with adoration. Most of them were in states of advanced undress, while a few were completely nude.

"Hello Harry." They chorused.

"This is… unexpected." Harry muttered, trying to hide the tent in his pants. "What are you all doing here?"

"We've come for you, Master."

"Master? What the fuck?" Harry wondered. He looked at his wrist.

"What's going on, Ascelon?" Harry asked the serpent.

It almost looked like the Ouroboros was smirking. "I don't know, Master. What, you expect me to know everything?"

"Lie to me," Harry warned "And I'll throw you into the lake after sealing you into this body."

Ascelon shivered. Swimming was never much fun. "Fine. I believe that you have an extremely active charm, much like that of a Veela, save that yours is stronger and much harder to control, at least on those you find attractive, anyway. It was rumored that those in possession of a Master Demonsoul were utterly irresistible to those of the opposite sex." Ascelon gave another snake smirk. "I believe that you will quickly end up with a sizable harem. Which is good, because your physical needs will be greatly enhanced."

Harry knew that Ascelon was cracking up at him. So, what, he would now be enslaving anyone he finds attractive. Hmm… Having a harem would be interested. What did Ascelon mean when he said his physical needs would be enhanced? He was definitely aroused, which would have explained the pain in his pants.

Before he could think of anything else, Harry was surprised to see the door swing open. A unkempt man with a long knife stood in the entrance to the dorm. Several of the girls screamed. It was a good thing that he'd used his powers to place something like silencing charms on the other beds.

"Sirius Black!" A girl he recognized as being Parvati Patil's twin, Padma, shrieked.

"Harry, run!" Hermione shouted.

"Harry?" Sirius asked, confused. "Harry Potter?"

"Sirius Black. You betrayed my parents. I'm going to kill you!" Harry screamed. A pulse of black lightning immobilized the man while Harry leapt over the crowd of girls, black energy forming claws at the end of his fingers. He positioned his hand over the man's chest, above his heart.

"Wait! Harry! I don't deny that it's my fault, but you should know the whole story!" Black shouted, struggling against Harry's power.

"What story? You were their Secret Keeper!" Harry spat. He had learned the whole story from Remus on their way to the castle.

"No! I convinced them to switch to another friend, since I was too obvious. Unfortunately, he was the spy! Peter Pettigrew has been free all of these years while I rotted in Azkaban!" He somehow managed to break the binding and ripped the wand from the nearest girl's grasp. Susan Bones glared at him indignantly, but was too scared of the man to fight for her wand.

"ACCIO PETER PETTIGREW!" He roared. Scabbers erupted from Ron's bed, squeaking as he flew into Sirius's hand. "This, Harry, is your parents' betrayer." He pointed the wand at the fat grey rat. A flash of light later, and a short fat man cowered in fear on the floor.

"Girls?" Harry said with a growl. "Do me a favor and bind him." More than twenty wands were raised to fire out a swarm of ropes and Petrificus charms. "Thank you." Wanded magic was more constant at the moment. It seemed that his power was less effective when he was tired.

He stalked over to the cowering man.

"H-hello, Harry. You look just like your fa-"

"Shut up." Harry snarled, barely managing to stop himself from reducing the man to dust. He had instantly known that Sirius had been telling the truth. Demon mind magic could be very helpful. "You killed them. They were your friends, and you…!" Flames burst from him, smashing into the man's right arm, instantly incinerating it. He ignored the man's screams while the girls just glared at the Death Eater.

"Thank you for believing me, Harry." Sirius said. "Now, let's kill him and get it over with." He raised Susan's wand. Before he could do anything, Ascelon snapped out and knocked it back to Susan.

"Are you an idiot?! If you kill him, you'll never be cleared!" Harry translated for the non-Parseltongue speakers.

"True." Sirius muttered. "We'll bring him to the Ministry, then you can leave those muggles and we can live together!" Even as he said the words, a bolt of orange flame smashed into Pettigrew, reducing him to dust.

"NO!" Sirius screamed as Harry started looking around. The girls were shrieking at the sight until he told them to shut up. He was furious enough without having to deal with their screams. He may not have to deal with the Dursleys' cruelty anymore, but that didn't mean he didn't want a family. Someone had done this. When he found whoever it was, they were going to wish they'd never been born.

Suggestions? I'm accelerating this year, just because not much tends to happen in 3rd year and I want to get it over with. Not sure why that is. 4th year is always fun.

I wonder if anyone can guess who killed Pettigrew? Just so everyone knows, the same person will probably be responsible for the death of Sirius. Harry's going to get pushed over the edge. As much as I like Sirius, hurting him the best way to truly piss Harry off.

Opinions? Suggestions? Like it? Hate it? I need comments, because I'm not a hundred percent sure how this is going, or if I should continue along this thread.
