Part One:

Severus closed his eyes and remembered the first time that he had seen 'her'. She had been Voldemort's favourite; she was beautiful, deadly and way out of Snape's league. Or so he had thought.

**************************

"Severus, I would like you to meet the newest member of our organisation." Snape looked at the girl, her black hair was cropped giving her face a sculpted look, she wore black leather, with calf high black boots, Sev with his nineteen year old hormones could hardly stop himself staring open mouthed at her. She was unlike any he had ever seen before; he surmised that she must be a witch because Voldemort would never tolerate a muggle, or a mudblood for that matter. But the lack of robes was disconcerting. She seemed to be eyeing him with as much curiosity as he was her. Their eyes met at Severus felt a spark of recognition but he couldn't think where he had seen her before. Sev held out his hand to her, which she took.

"Severus Snape glad to make your acquaintance." The girl looked at Voldemort as if asking what she should say. He answered for her.

"This is Blade, she is to be your new partner." 'A partner, what had happened to Lucius?' Lucius and Severus had always worked together; they were even initiated on the same day.

"You must be wondering what had happened to Lucius and the answer is nothing 'yet' but is a waste of your considerable talents, you will serve me better with an adequate partner and my little Blade is more than adequate. You may leave now and get to know each other but stay close at hand I might have a job for you soon."

The two of them left Voldemort's study and went to the lounge. Severus was bursting with questions. He knew the Blade couldn't be her real name but clearly Voldemort didn't want him to know who she really was, he would never risk Voldemort's anger by asking but there were plenty other things he wanted to know. He turned to face Blade. She looked at him steadily with her emerald green eyes.

"Well Severus, I guess we should know something about each other if we are going to be working together." She said.

"Sev" He corrected absentmindedly, he had always preferred to be called Sev.

"All right Sev it is. I am Blade, my speciality is charms, but I also have an affinity for Muggle weaponry." She made a little movement with her left forearm and a dagger appeared in her hand, she twirled it round her hand before putting it away.

"Guess where the name Blade comes from?" She purred. There was no need for him to guess it was fairly obvious, now, that the name came from her affinity with knives. It was a strange skill for a magic person to have; most couldn't do any kind of fighting other than with a wand. Sev was an acceptation knowing how to use firearms. He knew the advantage of being able to kill with out magic, most magic folk would not be able to defend themselves from a form of muggle attack, so it was often more effective. Sev smiled at Blade it seemed like he had found a kindred spirit, someone who believed not everything had to done with magic.

"I am a Potions Master, able to brew the most complex of potion's. But that is not my real passion." Sev reached behind his back and pulled out a handgun, holding it easily almost as if it was part of him. He smiled lazily at her.

"Maybe not as elegant as a knife but you'll end up just as dead." He added. He placed it back into its holster. He looked at Blade and sat down on one of the many chairs scattered around the room.

"Mind if I join you?" She asked, a seductive lilt to her voice.

"Not at all." He replied gesturing at the seat next to him. She sat down heavily her thigh touching him. It sent a thrill through Sev; he had ever been this close to a beautiful girl before. He turned slightly towards her and saw her looking at him. A dark light in her eyes, Sev could well imagine his eyes held the same dark fire, it was a look only thoughts of sex could create. He leaned slightly towards her, as if going for a kiss, but what he was going to do was never found out. A sharp pain shot through his arm, and by the way Blade was clutching her own arm the same thing must have been happening to her. He looked down at his arm and saw the dark mark burning out against the paleness of his skin. Voldemort was calling them.

They both entered the study, which they had only left an hour or so before.

"I have a job for you." Voldemort announced. Sev's eyes lit up, a job already, it was his lucky day.

"Just say what you want from us and it will be yours." Sev said.

"I want you to destroy a club for me, well kill everyone in it anyway. This mission doesn't serve much practical purpose, excepting for ridding the world of some more muggles. It is more of a training mission to let you practice working together, undercover work and your own special skills." Sev and Blade looked at each other, there were getting a free ticket to go out and 'play' with muggles what could be better. Voldemort looked at the two of them closely.

"Blade you are dressed perfectly but Severus you can't wear robes." Voldemort made a little gesture with his wand and a pile of clothing appeared on his desk, he handed them to Sev.

"These should suffice. Go and get changed, then come back here and I will tell you where the club is."

Sev and Blade left the room once more, He climbed the stairs to his room with Blade following slowly behind. They stopped outside a door.

"Do you want to come in?" Sev asked. He opened the door and Blade followed him in. Sev stepped behind a screen to change when he let out a groan.

"What's wrong?" Blade asked. He held up a pair of pants to her, they were black leather.

"I can not wear these." He stated.

"Yes you can, and you will because if you don't Voldemort will be pissed." She reminded him. Sev snarled, Voldemort would have his head if he didn't wear his little creation. He changed resignedly. After a couple of minutes he stepped from behind the screen. It was Blade's turn to stare open mouthed. Sev looked, for lack of a better word, hot. The black leather pants clung to his body showing it of to perfection, the black silk shirt moulded itself to his perfect torso. Sev laughed a very masculine laugh.

"I am glad you approve." He said, noticing her practically drooling over him. He wandered over to the mirror and as much as he hated to admit it, the outfit suited him, much more than any robe ever had. His pale skin gleamed, emphasised by the silk. His black hair was like silk itself. The boots he had for the outfit made him walk like a predator.

The club was packed. Blade and Sev moved slowly through he crowd wondering where to start. The undercover part of the mission worked like a charm, not one person looked at then suspiciously, a lot of people looked. but not suspiciously. A lot of the patrons liked the leather. They had decided before hand that they wee not going to use magic, just good old fashion brute force.

Sev leant down close to Blade's ear.

"I say one of us starts at the back the other the front and we meet in the middle." He whispered. Blade nodded and moved towards the back of the club while Sev moved to the front. Then the fun began.

It was a blood bath.

******************************

Sev looked down at what he was wearing it was very like what he had worn that night. From that night on he had dressed like that, it felt right. Plus Blade liked it. He continued to wear it even after she had disappeared; it made him feel closer to her. Sev closed his eyes, tears were threatening to spill. He had lost his lover and master in one night and he couldn't even show grief. If he had Dumbledore would know he never was on the side of good, he always had been and always will be Voldemort's loyal follower.
