A/N: Welcome to the AC crossover! I know I said I would only work on one story at a time , but I just had to write this! If I kept it any longer, it would have evaporated from my brain. Anyway, enjoy!

THE CALL OF THE CREED

CHAPTER 1- Prologue

I reach the end of the trail. The air is still, and I am a hunter. The hunt has led me to the forgotten edges of this world. Seasons have passed, drawing me deeper into the darkness, where I have found the truth. That my redemption is found in ashes, that I must burn away the past to set things right.

The Assassin lowered his hood as he walked towards his victim, who was trying to staunch the flow of blood from the hole in his shoulder. Looking down, the Assassin saw the red cross necklace that confirmed his suspicions. Reaching to his waist, he grabbed his sword before transforming it into its rifle configuration and pointing it at the victim's head.

Once a Templar, now their pursuer, I must destroy those who I once called brother. The air is still, and I am a hunter.

The resulting BANG echoed throughout the valley.

5 years earlier...

"C'mon Ryan! You must learn to move as your opponent does. Anticipate the next attack, and block it. If they dodge, keep up the offensive. As soon as you see an opening, go for it!"Adam said as Ryan was put to the floor, for what seemed to be the hundredth time that day, by Adam's elder brother Jamie, who hadn't spoke a word since Ryan had asked for a sparring partner.

Grunting in frustration, Ryan pushed himself into a sitting position, looked at his friend, and brother-in-arms, and said, "Well, just because the great Robertson trio graduated to Master Assassins before the rest of us, doesn't mean that we all can be as good!", wiping his brow with a towel that Jamie had thrown his way. "We didn't graduate to the rank of Master by getting the easy treatment, and so, since you're on our team, neither will you. Now on your feet!"Adam said, stepping on to the ring and pulling Ryan to his feet before turning to his brother. "Never the less, congratulations are once again in order, Jamie. You are certainly a sight to behold in the ring. Now, I believe that you owe me a fight after beating Ryan. Sound good?"he said, Jamie nodding before stepping back to the middle of the ring.

"Prepare yourself for an ass whooping, little brother!"Jamie sneered, confident in his years of experience over his brother. This simply caused Adam to smile and say, "Overconfidence will get you killed, brother. Surely you must remember this", causing his brother's smile to falter. Adam then noticed that the clock behind his brother was reading 11:35, meaning that they had 25 minutes before their team's briefing with the Mentor. "Well, best make this quick"he thought to himself, as he ran towards his brother. After a few seconds, and a few crunches of bone meeting bone, Jamie lay flat on the ground, as Adam stood triumphantly above him. "Told you", was the snide remark he let out, offering a hand to his brother. After pulling him to his feet, Adam said to Jamie, "Right, go and get yourself cleaned up. I seem to have reopened an old injury of yours. Kayleigh will see to it. I'll let the Mentor know where you are." Jamie simply nodded, and headed towards the medical bay. Kayleigh, their team nurse and good friend, followed him not long after.

"Adam, shouldn't we be heading to the briefing?"the voice of his sister Libby piped up, drawing Adam's attention. "Oh, shit! Right, let's go!"he said, hurrying out the door. A couple of minutes later, they were outside their Mentor's quarters. They saw that the rest of their team: Ryan Clougherty, Shannon McCafferty and Cameron Goldie, were already present. "Who's turn is it?" Adam asked, his team glaring straight at him, causing him to hang his head in shame. "Alright then, here we go", he said, raising his hand and knocking on the door.

"Enter!"

No matter how many times they entered the chamber, they never ceased to be both amazed by the amount of knowledge held in this room, and scared by the man who it all belonged to. Their Mentor, a man who led their branch of the Assassin Brotherhood, was certainly no pushover, but people could tell that he was growing progressively weaker due to age. This didn't take away from his many contributions to the Brotherhood, but some people, and some Assassins, looked at him as a laughing stock. Adam, Jamie and Libby certainly didn't think so; the three of them were saved from a life of hardships by the Mentor & trained to be Assassins, and they thanked the Mentor for giving them what they believed to be their "Calling in life."

"Reporting, Mentor! Forgive them, but Jamie and Kayleigh will be later than usual, due to me reopening an old wound of Jamie's, and Kayleigh taking a look at it. So, anyways, you asked to see us?"Adam said, the Mentor nodding in confirmation. "That I did, lad. I hoped to talk to your whole team, but..."the Mentor started, before the door behind Adam opened and in walked Jamie and Kayleigh. "Apologies, Mentor. We thought the injury was more serious than it is in reality." Jamie stated, the Mentor nodding. "Ok, now I can get to the main reason for asking you here." Cameron, who always was a little hot-headed, piped up, "I take it you have another mission for us?", causing everyone present to be surprised at his bluntness, but the Mentor simply smiled.

"Aye, lad, you'd be right in saying that. Now, I know that you work well as a team, but I have to get this out of the way. Adam, step forward."the Mentor said, Adam doing as asked, before continuing. "Of the Brothers and Sisters standing beside you, who would you say would be the best to lead?"he asked, Adam turning to look at his team, before quickly making his decision. Turning back to the Mentor, he said, "I would say Jamie, Mentor, given his years of experience, as well as his leadership skills. I have counted a number of times where Jamie has had to lead the team due to me being handicapped in some way. I can think of no one better suited to the role", Jamie smiling at his statement.

The Mentor nodded, before asking, "If I was to make Kayleigh here the leader, would you follow her?" Adam simply nodded, but also said, "While she wouldn't be my first choice for a leader, if you believed her to be perfect for the position, I would follow her." At this, there was a faint smile on the Mentor's face. "That's what I thought."he stated, before reaching into his pocket and withdrawing a small round disc. "Catch!"He said, tossing it to Adam, who simply caught it one-handed. Looking at it, he saw the disc had the unmistakable sign of the Assassin Brotherhood on it. Looking back to the Mentor in confusion, he asked, "What does this mean, Mentor?", the man in question laughing slightly.

"The time of referring to me as "Mentor" is over. You are Mentor now, Adam. The Mentor, of the Valesian Assassins..."

A/N: And I bet the lot of you saw that ending coming! Given Adam's position in RoTA, I felt he would be the best candidate for Mentor. So let's see how their team copes with liberating Vale in the later chapters. Until next time!
