I know that the X-Files/HP crossover has been done, but I thought I might take a try. This monstrosity comes from five days of doing nothing but watch the entire first season of the X-Files and reading fanfiction.

Disclaimer: I don't own any characters pertaining to the X-files or Harry Potter. They are owned by J.K. Rowling and Chris Carter respectively. I don't make any money off of this.

Hope it doesn't suck!!

Under the cloak of darkness, Fox Mulder stalked his prey, a serial killer with tendencies to drink his victim's blood. A vampire, according to Mulder. His partner and more level-headed friend, Dana Scully, crept around the opposite corner with the intention to trap him between her and Mulder.

Suddenly, he spotted her and lunged. She side-stepped him, just barely, and Mulder jumped on his back, knocking him to the floor of the deserted warehouse in London. There was a small scuffle until finally Mulder pinned the man's hands behind his back.

"Scully! Call for back-up!"

Mulder scrambled to keep his hold on the man who goes by the name Gren as he reached for the spare rope by his side that had originally been used to hold storage boxes together. Gren wriggled out of his grasp and leapt up to run. Scully pulled out her gun and fired a warning shot. Gren kept running and Scully chased after him, Mulder right on her heels. Gren ran blindly through the landing, smashed into the steel bar by the stairs, flipped over it and fell to his death, three stories below. Scully stared down into the darkness, leaning slightly over the bar as Mulder skidded to a stop behind her. He saw the expression on Scully's face and immediately came to the right conclusion. He sighed, defeated and grabbed his cell phone to call Head Quarters. He stalked off to try and find a spot with better reception. As he finished relaying the message on a solemn note, he heard light footsteps from the shadows. He silently motioned for Scully to follow him, gun raised after the slight noise.

As Scully went to turn on her flashlight, Mulder motioned not to and clasped her hand in his so she wouldn't get lost in the flowing ebb of shadows. As they drew nearer to the sound, they could see the silhouette of a man standing in black robes lined with silver, contrasting the moonlight that leaked through the window.

Mulder slowly put his gun in the holder and reached out his free hand towards the domineering figure. As he placed his hand on the persons shoulder, he felt an odd tug at his navel and suddenly realized that he was in a small clearing in a forest, sprawled next to Scully on the damp grass.

"What just happened?" Scully asked quietly in Mulder's ear as the other figure spun around in surprise to reveal a man with shoulder-length, greasy black hair, a pointed nose and a sour look on his face.

"And who, may I ask, are you?" his bass voice boomed as he towered over the two agents. They looked at each other nervously, wondering how they would get out of this.

*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*

Severus Snape strode quickly down, past the Hogwarts apparation barriers and disappeared only to reappear in an empty warehouse, in some obscure London location. He clutched his left fore arm to his chest, occasionally hissing in pain.

Now, I'm sure you're wondering why Severus Snape, Potion's Master of Hogwarts School of Witchcraft and Wizardry is apparating to a deserted warehouse in London. You see, Severus Snape has been acting as a spy for the Order of Phoenix, taking information from Death Eater meetings and reporting back to Headmaster Dumbledore.

Since the return of the Dark Lord the past year, security around Hogwarts has increased, including the wizarding town of Hogsmeade, located at the outskirts of the school property. Instead, to get to the meetings, Severus has to apparate first to the empty warehouse in London, just incase some one tries to follow him. From the warehouse, he takes a portkey to the meetings.

After apparating to a dark room, he pulled out his wand and whispered "Lumos". The room took on a greenish glow for a few minutes, before deciding the location was secure and muttered "Nox", which extinguished the light.

He moved over to the window that was half boarded shut and stared out into the inky darkness as the moon peeked out from between the clouds, illuminating his figure softly. The mark on his arm burned again, twice as strong as before, meaning that his mental preparation time was over. He removed himself from the sight of the street and reached for the portkey in the shape of a cat figurine.

Just as he felt the familiar pull at his navel, a hand clamped on his shoulder. He spun around in surprise, having thought the location was secure and as the forest materialized before him, he noticed the two people who tagged along for the ride were thrown haphazardly to the ground. He quickly surveyed them to find a man and a woman. The man had light brown hair and a serious expression to match the business suit he wore. The woman, with hair almost matching the Weasley's wore a suit slightly matching her partners and just as shocked an expression as Snape did.

Severus pulled himself together quickly and asked them in a non-committal tone, "And who, may I ask, are you?" He gave them the pointed look he reserved for Neville Longbottom and he saw them exchange some nervous glances. The man stood and reached into his jacket. Snape saw the movement and instinctively pulled out his wand and trained it on the two strangers. The woman gave him an odd look as her partner pulled out a badge of sorts.

"I'm Special Agent Mulder, this is Special Agent Scully," he started, pointing at his counter part. "We're with the FBI. We were investigating a serial killer in the warehouse when we came across your figure. Not knowing who you are or what you were doing, we were approaching you and . . . now we aren't where we were before . . ." he trailed off, a confused expression painted across his features. Snape just stood, silently pondering what an FBI was.

"We're very sorry for the inconvenience, but we probably should go. Our case has to be wrapped up and being here while the crime scene is being checked out will not do wonders for our already skeptical reputation. It was a pleasure to meet you . . ." Scully trailed off, moving backwards slightly. It was then that Severus realized they were muggles. Before Voldemort could find them, he had to get them out of the presence of the Death Eaters. Snape stopped her with his commanding aura and conversational tone.

"I'm afraid I can't let you do that. Because I have exposed you, I must bring you back to the safest place I know of. Trust me enough to follow and get yourselves out of danger. We must go quickly, before we are caught. Take my hand and I will get you out of here . . ." Severus held out one hand to Mulder, one to Scully. They looked at him incredulously and began to back away. He stepped forward and raised his hand higher, silently urging them to take it.

"If you don't come with me now, I can't be responsible for what happens to you in these dangerous parts. This place isn't safe for anyone, least of all you two. I will explain everything as soon as I can, but I need you to trust me."

Mulder exchanged a glance with his counter-part and shrugged. As they moved towards Severus, voices approached from the trees surrounding them. Snape looked up in surprise and motioned for them to move faster. They grabbed his hand as the figure advanced, wearing a matching black cape lined in silver and white mask. The mask was whipped off in surprise and the eyes of Lucious Malfoy locked on Snape's for a second before they disappeared with a faint pop.

Lucious stared in astonishment for a second before his face returned to the smirk his son had made famous around Hogwarts. He turned and strolled back the way he came, eyes gleaming maliciously in the dark at the news he would bring the Dark Lord . . .

A/N: Well, there you have the first part. I have a lot of great ideas for this story and I'm hoping it will bring me out of my writer's block on the other stories I have. If you like it, review. If you hate it, review. If you are undecided, review. I'm needy. Thanks!
