Hello, this is the first time I've written anything for Assassin's creed, on or offline. I only recently actually got into it, despite me perfecting the first one, but it is one of the few games that interests me because of its stealth option aspect. So, I decided to do a crossover with one of my other favorite game series Mass Effect. Note, I did a lot of research to make sure all of this would be cannologically correct for both series, and/or make sense, so small details will be AU.

"Nothing is true. Everything is permitted." These were words that David Anderson heard, for sixteen years of his life. He had once asked his father what they meant, but received only a riddle instead. Today though, he knew exactly what they meant, these were the words of his creed; Of the Assassin's Creed. They were the wisdom and now he was ready for his initiation.

He took a deep breath, and pushed open the oak doors. Along the sides of the velvet carpet, there were dozens of men and women all wearing hoods, and all brandishing the otherwise invisible mark on the back of their hand. He walked down the aisle of multicolored hoods, to the Mentor. He bowed his head as he removed his own white hood.

"Laa shay'a waqi'un moutlaq bale kouloun moumkine." His voice was deep and throaty, giving evidence to his german background. "Through these words the wisdom of our creed is revealed." He picked up the holo-brand and prepared to put it on David's hand. "Where other men blindly follow the truth, remember..."

"Nothing is true."

"Where other men are limited by morality or law, remember..."

"Everything is permitted." This part of the mantra was spoken by everyone present to the ceremony.

"We work in the dark to serve the light." He pressed the brand to David's hand, "We are Assassins." After the brand finished setting in, the mentor turned and gestured for David to follow him. The two assassin's walked up a long flight of stairs to the hideout's roof. There was a yard-long protrusion from the edge of the roof. The Mentor walked out to the edge of the protrusion, and preformed a leap of faith.

David took a deep breath and followed the Mentor, landing inside the lake that touched the edge of the hideout. He swam to shore, and put his hood back on as he looked at the Mentor, "I am ready," he said with a steady voice.

The mentor pulled from his robes a silver canister, "Your first contract as an assassin will be in Vancouver. There will be a plane that leaves for Canada tomorrow in London."

David opened the canister, and inside was a hidden blade, other equipment he would need, and the details for his contract. He nodded, and bowed to his mentor. He then ran to the garage. He grabbed a motorcycle and started towards London.

The next day: 8:00 PM Vancouver time.

David was sitting in a bar, looking over his contract as he drank a very weak brew.

Name: Jonathan Shepard

Sex: Male

Age: 42

Nationality: Native American-Canadian

Skin complexion: Caucasian

Eye color: Grey

Height: 6'3"

Profession: Abstergo CEO, running for high-ranking political office.

Bio: Shepard has been a Templar since his earliest years, he has been on our watch for some time now, but we fear that Abstergo industries will gain control of Canada if we allow him to take office. Despite his openness to the public, he is adept at keeping his location with those he wants, and out of the hands of those that he doesn't. We only know that he frequents a bar call 'Christ's lounge' and...

David chuckled internally, due to the fact that he had actually walked into the Christ's Lounge. He continued reading the dossier.

...'Christ's Lounge.' Do not kill him in public, or you the Templar's will hunt you down. Make it look like an accident inside of his home, this will require of you to follow him. It is known that he is a recent widow, and has a child. Bring the child to us if possible.

David raised his brow, and rubbed his forehead. He put the Dossier into his bag before anyone could see it, then heard the door open, and turned his eyes to see his target walk in the door. He pretended not to notice, and continued drinking his brew. After he finished, he paid and walked out of the bar. He walked down the street a little, and turned into the second alley. Despite it being 8:00, there was still a fair amount of people on the street, and David counted it as a blessing.

After an hour of patiently waiting, Jonathan walked out of the bar, and turned in the opposite direction of David. He came out of the alley, and followed him. David crossed to the other side of the street so that he would avoid suspicion, and walked behind a crowd a civilians.

Following his target was easier than David anticipated, and Jonathan led him straight to his apartment. David waited for his target to go inside before crossing the street, and following him inside. He was just in time to see Jonathan get into an elevator. David ran to the elevator, and took out a small device from his backpack, and put it to the elevator door, and they opened just enough for him to slip inside. He removed the device and started climbing the elevator shaft. He was climbing faster than the elevator and soon caught up. He climbed above it, and crawled on top. David rode it all the way to the floor that Jonathan did, due to it not stopping on any other floor. He waited for a few seconds to see if it would keep going, before he opened the hatch and climbed down. He opened the elevator door, and silently jogged down the hall.

He stopped at a T in the hallway, and looked around the corner. He saw Jonathan enter a room, and memorized the distance from the end of the hallway and which way it faced. He walked to the window at the edge of the hallway, and climbed out. He made his way across the side of the building, and back to Jonathan's room. He peeked his head over the window to see the Templar putting his child to bed, and dismissing the babysitter. He took a deep breath, and opened the window soundlessly. He climbed in and hid behind the couch.

Jonathan walked into the room, and noticed the open window. David heard him take a deep breath. The footsteps started getting closer to the window, then they stopped. David's body tensed, and he didn't expect the Templar to pull him from behind the couch and slam him into the floor.

David recovered from the shock quickly, and rolled out-of-the-way before Jonathan's fist made contact with his throat. He swept the man's legs out from under him and rolled away. David got to his feet at the same time that Jonathan did, his back facing the window. They were at a standstill; Jonathan wasn't going to charge because David would move out-of-the-way, and he would fall out the window. David wasn't because Jonathan had the advantage of strength.

David took out a clear carbon-fiber rope from his pocket, and lassoed it around Jonathan's neck, and pulled it taught. Jonathan gagged from the tightness, and hesitated for a second, not expecting the rope. After he recovered from the surprise, he grabbed the rope, and pulled David towards him. David spun behind Jonathan, and pushed him towards the window.

Jonathan was able to catch himself before he fell out, and turned around just in time to tie part of the rope around David's wrist, as the man pushed him out the window.

"Any last words Templar?" David asked, as he took out the detachable knife from his hidden blade.

"MY DAUGHTER!" Jonathan shouted, "Make sure she isn't dragged into this war!"

David hesitated to cut the rope, "Why should I grant you this wish?"

"Because, the Templar's wouldn't."

David looked at Jonathan, and knew that taking the son and making him an assassin against his will was something a Templar would do. He nodded, "I will make sure your son doesn't get dragged into being either an Assassin or Templar. What is her name?" David's arm was getting weak, and he would have to cut the rope .

"Jane... Jane Shepard. Thank you, Assassin."

"Rest in Peace." David cut the rope, and watched Jonathan fall. "May the end you sought, be the end you found." He heard a Jane crying in the other room, as if sensing the death of her father. He walked into the child's room and cradled her in blankets.

An hour later.

David took Jane to an orphanage that was small, but had no ties to Abstergo industries. He put his hood over his head before knocking on the door. A woman answered him, "What is it?"

"Take care of this child." He gave her Jane, and walked away without another word. He had left a necklace on the child's neck, so that he could identify her if they ever met again.

David took a cab to the airport, and boarded the next flight back to London.

The Assassin's hideout.

David entered the Mentor's room, and bowed, "I am sorry, but the child was not at his residence," he lied to his Mentor, "but I have completed the contract."

"Good, it is too bad about the child. I am sorry, but there is no rest for the weary. Your next assignment is a bit more permanent," He gave David a dossier, "you are to enlist in the Alliance Navy, and attempt to locate all Templars of high Military rank."

"I understand," David said, "I will leave as soon as I get food and rest. I will not fail you."

"For the brotherhood's sake, let us hope you don't. There is another Assassin that will join you when the time is right."

"Who is it?"

"For now, I cannot say, but you will know when they appear to you."

"If that is all, I will take my leave." David bowed, and left.

So, this was my first attempt at writing an Assassin's Creed-esque story, please tell me how I did, because I can only get better. Oh, and after this, it will focus on Shepard.
