This is my second mediocre vampire fanfic because I am author trash.

Anywho. I haven't read the books in years, so I'm mostly going off the movie plot… but only very loosely.

I own nothing, as always.

Summary:

Voldemort delivers a devastating blow to the light side when a vampire child tasked with killing Harry Potter infiltrates the school as a first-year student. Harry is rescued from the murder attempt by the school's DADA* professor, but not before he is bitten. Actions are taken to help Harry survive the transition, but Potter Luck ™ strikes again and things go very pear shaped indeed.

*DADA professor, more like DADDY professor (͠≖ ͜ʖ͠≖) huhuhu~

I'll leave.

After enduring the worst summer of his life, Harry Potter was finally home in Hogwarts' hall. He was sat amongst his fellow Gryffindors enjoying the welcoming feast, and feeling cheerful for the first time in a long time. The new first-year students had already been sorted, and Dumbledore had given his welcome speech. It was a doozy of a speech this year, it threw nearly everyone for a loop when Snape was announced as the new DADA professor. The only reason Harry wasn't catching flies with the rest of them is because he had been involved in recruiting Slughorn as the new potions professor. He was starting to get sick of being so desirable to obscenely old men. Voldemort wanted to kill him, Dumbledore wanted him to kill Voldemort, and Slughorn just wanted him. Ah, and there went his appetite.

"S'matter Harry, you're looking a little off." Said Ron from beside him. Harry just shook his head.

"Nothing. I was just watching you devour your chicken, and now I can see why Hermione is always appalled by your table manors." He replied with an impish smile. Hermione was looking rather vindicated at having Harry take her side on Ron's eating habits. Ron, on the other hand, frowned at him and opened his mouth to show off his half-chewed food in retaliation. Harry let out a bark of a laugh.

"Gross, mate!" he exclaimed, and laughed again when Hermione smacked him on the arm and lectured him about setting good examples for younger students as a perfect. It wasn't the first time Harry was glad he hadn't been made a perfect. Harry turned to Nevil who was sat across the table from him.

"Hey, Nevil, what does your schedule look like for this year? Did you continue Care?" he asked.

"Oh, y-yeah actually I did. I thought it would be better than arithmancy. I also took Herbology." Replied Nevil.

"If you feel like taking a third elective you should take Divination, Harry bailed on me." said Ron.

"Err, no thanks. I don't really find that class useful… at all. Also, she makes a lot of death predictions and it kind of freaks me out." Said Nevil.

"Ehh, it's a good excuse to drink tea and make up unfortunate predictions for the Slytherin's though. The class is an easy grade." said Ron. Hermione, who was prone to lecturing Ron for being lazy, let this comment slide. Her dislike for Divination outweighed her desire to encourage Ron to try harder in his studies.

"Yeah, that's true, it's an easy grade." Echoed Harry with slight regret. Honestly, he was going to drop Care so he could join Ron in Divination, but he couldn't imagine what Hagrid's face would have looked like if they had told him all three of them wouldn't be returning to his class. Besides, he actually did like Care of Magical Creatures, he still got a little thrill every time he saw a new one.

"It's such a waste of time though." Said Hermione, "What other electives did you decide on, Harry?" she asked.

"Oh, just Ancient Runes." He said. Hermione nodded her head.

"We'll have that together then. I wish you two would consider taking Arithmancy, now there is a class with a purpose." Said Hermione.

"Look, Hermione, I'll consider it." Said Ron. Hermione instantly perked up with surprise.

"Really?" she said. Ron nodded his head.

"Sure! I'm considering it right now, and I have to say… no. It sounds awful." He said, grinning as Hermione's face soured.

"Honestly Ronald, real mature." She said, but Harry caught the smile she was trying to hide with her glass of pumpkin juice. Harry had a smile on his face himself, honestly it was great being able to see his friends again, he was feeling hopeful that this year wouldn't be as difficult to bare as he had imagined. After losing Sirius last year, and then spending quality time with his abusive aunt and uncle over the summer, Harry's mental state had taken a real nose dive. Even he had begun to notice how angsty and irritable he had been acting over the summer, and even on the train. If he could get in a few peaceful weeks at school, perhaps he'd feel more like himself. Of course, Potter Luck wasn't going to allow that.

It was nearly curfew as Harry was walking back to the Gryffindor tower when he heard the sound of sobs coming from inside a hallway broom cupboard. He'd been distracted by his thoughts and nearly missed them, but the sound of the broom closet door being shook snapped him out of his daze.

"Hello?" came the muffled voice of a young boy from inside the closet. "Is someone out there?" he said. Harry looked around the hall for a teacher or some perfects who could deal with the situation only to find it empty. Harry sighed in disappointment. Were kids hazing the freshmen on first day already?

"Yes. I'm here. Hold on, I'll open the door." Said Harry as he walked back to the broom closet. With a quick wave of his wand Harry unlocked the door a pulled it open. A young Slytherin boy was curled up in the closet, blinking up at him. "Err, there you go. Better get to your dorm, it's almost curfew. Make sure you tell a teacher if someone is bullying you." Said Harry, as he made to walk off.

"Wait! I can't see." The kid exclaimed, stopping Harry in his tracks.

"Pardon?" he said.

"I can't see, the kids that locked me in here hexed me first, and now I can't see." He said. Harry pulled off his own glasses and pinched the bridge of his nose. He was likely going to be late for curfew himself now, if he got caught in the halls by Snape he would get detention for sure – good reason or not.

"Alright kid, hold out your hand. I'll lead you to Madam Pomphrey." Offered Harry. The kid reached out his arm.

"Thanks, means a lot!" the kid said with a bright smile. Harry frowned and took the kid's hand. He was rather friendly for a Slytherin. In hindsight, maybe that should have been some sort of warning sign. A moment later Harry found his hand locked in a vice grip as the kid pulled him forward with a hard tug, he braced his free hand against the cupboard in his attempt not to crush the kid. Harry opened his mouth to start yelling at the little brat when a sharp pain in his neck cut him off, and caused him to cry out in pain instead. It took him a half a moment to register that the kid was biting his neck, and then the struggle was on. The kid, or rather vampire, was nearly a full foot shorter than Harry, and still he couldn't shove the kid off him. He tried to reach for his own wand but the kid was quick to pin both of his arms to his sides. Harry found himself starting to grow dizzy.

"What the hell are you doing? Get off of me!" Harry yelled, thrashing in the kid's grip. The kid didn't answer or let go, and Harry could feel himself growing faint. He and the vampire went crashing abruptly to the ground once Harry was too weak to hold himself up. Was this how he was going to die? Drained dry by a baby vampire on his first day back at school? Harry wasn't sure if it was more pathetic or tragic. God, his neck was on fire. Faintly, through the pain and the blood loss, Harry could hear a voice speaking in the distance. Right… why hadn't he called for help? He tried to call out to the voice, but all that came out was a weak moan of pain, and then Harry knew no more.

Harry Potter had been rushed to the infirmary in critical condition. The news had spread through the school the next morning like wildfire. No one in the great hall knew the reason for his injuries, except for one man. Black eyes roved over the gossiping student body, lingering over the faces of his snakes. He had no idea how a vampire managed to smuggle himself into Hogwarts undetected. Worse, it had been revealed to him that the vampire had been sent to Hogwarts on Voldemort's orders with one task, kill the Potter brat. It had been disturbing news, on a number of levels, but what bothered Severus most was that Voldemort hadn't informed him of this plan. He was afraid that his days as a spy, and a living being, were numbered if the Dark Lord was starting to keep secrets from him.

Albus had been less than pleased with the newest turn of events. He had grilled Severus relentlessly about the Dark Lord's recent plans and conversations, trying to discover anymore secret plots before they could come to fruition. It was all for naught though, Severus simply didn't have the answers. This plan had been nearly successful in killing Potter, if Severus hadn't been in the right place at the right time, the boy would already be dead. As it was, the boy was still not out of the danger zone. He was starting to turn. Madam Pomfrey was at his bedside constantly, monitoring the boy for changes and trying to keep him alive through the change. Albus had run off to gods knows where in search of a possible way to stop the boy from turning, and Severus, he was left to clean up the mess of whatever happened next. Live or die, Potter's fate would have dire consequences for the light side in the coming war. Especially if the Vampire Clans were already aligned with the Dark Lord. If the Order had any luck left at all then this vampire had been acting on his own, and not under clan orders.

Severus thought back to the state he had found the boy in. When he had heard Potter shouting down the hall he had expected to see him fighting with Draco, or something equally asinine. Instead he had seen the boy falling to the ground, a kid attached to him by the neck, and blood staining his clothing and the floor. He had been quick to act, blasting the vampire child away and restraining him. He had watched as unfocused green eyes gazed passed him while he tried to stay conscious, but with a moan of pain that might have been a plea, the boy had passed out. It was pathetic. It was tragic. How could one boy be such a magnet for trouble? To top it all off, Severus had very nearly broken his vow to protect the boy. If he hadn't realized what was happening in time, then where would he be? Dead? Without magic? The kid was honestly more trouble than he was worth. Still, after all of the time and effort Severus had invested into keeping his scrawny ass alive, Potter had better survive his transition.
