Prologue
It had been waiting a long time for a chance to speak to its host. A being such as itself was not known for its patience and had quickly grown angry at being imprisoned, however as much as the beast wanted to be free another part of itself, a part far older than the beast, a former human like its host was trying to reign in the beast demonic bloodlust that wanted nothing more than to break free of the small boy who was its host and rain destruction upon the village that had sealed it away. For you see the being that had was imprisoned had not always been a the beast it was now, it was once a man named Revan, a man who once a Jedi who in wanting to protect the innocent lives being slaughtered by a great army that was sweeping across the galaxy crushing all resistance. And while his intentions may have been honorable he was quickly corrupted by the power that he wielded and fell to the dark side, eventually becoming a dark lord of the sith that was feared even more so than the army that he had defeated.
Revan was eventually defeated by what remained of the Jedi Order and was thought to have been killed in punishment for his crimes, however what none of the Jedi knew was that the Force, the power that made the Jedi so powerful was not simply an energy that bound all life together but it had a will of its own and was alive. This being felt that death was not sufficient for the man who had killed billions of people and decided that Revan's punishment would be to be sent to a distant planet that had no knowledge of the Force or of the fact that there were thousands of other planets with strange and wondrous beings inhabiting them.
Upon appearing on the planet Revan quickly learned what happened, but being sent to an uncharted planet was not the worst part of his punishment, the Force had made him immortal but stripped away his ability to use the Force. In the end Revan's hatred of what had been done to him changed his soul into that of a giant nine-tailed fox that quickly became known as the Kyuubi, the most powerful demon that world had ever seen.
Now despite his past, Revan would have never tried to calm the beast that he had become but for the first time in his long existence on this world he felt something that he hadn't felt since before his imprisonment, the Force. Even without his ability to wield the Force he was able to feel the strength of this boy's connection to the Force and was curious as to how this came to be; curious enough that he was calming the beast so that he could eventually summon the boy's mind to him, allowing him to speak directly to the boy.
All he needed for that to happen was for the boy to become injured enough so that he could summon the boy's mind into his cell. Having been able to see into the boy's memories he knew this wouldn't take long as the boy constantly being chased and beaten by the villagers, who hated his container for having the Kyuubi sealed within him. The villagers in their rage and grief over their dead families and friends who had been killed by the Kyuubi could not understand the boy, Naruto, was not the beast but simply its jailer.
In fact at this very moment Naruto was being chased by these very same villagers and was about to be cornered in a back alleyway that the boy had run into. When the villagers finally caught up to him they showed no mercy, using clubs and knives and clubs to beat the him until he was barely breathing and laying in a puddle of his own blood.
Inside the seal another being had just entered the cage that sealed the beast the villagers were trying to kill. This being was the Force, who had taken on the appearance of a kindly young woman and was immediately attacked by the Kyuubi who in his hatred of her tried to kill her, ignoring the protests of the former Jedi within him. Raising her hand the woman flicked her wrist at the giant demon and sent him hurling across the cell into the far wall, where she pinned him there.
"Now that was inappropriate," the woman said calmly, however her voice was laced with power.
Growling the Kyuubi eventually realized that even with all the power that he had obtained as a demon he was still no match for the woman in front of him and calmed enough for Revan to regain control. "Why have you come?"
Smiling beatifically at the former Jedi in front of her she said "And I thought that you would be relieved to see me."
"You banished me to this planet and took away my power, why would I be happy to see you?" Revan spoke angrily.
"First it was never your power, it was, is and always will be my power, never forget that" She spoke emphasizing the last part. "And I am here to offer you a chance to end your suffering."
"What!?"
"You want your freedom, your power, and your mortality?"
Growling he replied "You know I do. What's the catch?"
"As you are no doubt aware, your host has the ability to become a Jedi. However with no Jedi on this planet to train him his potential will never be reached. In exchange for your freedom, your power and your mortality you will have to teach this boy in the ways of the Force. He will be needed in a few years, the chosen one approaches and he will need the guidance of this one to avoid an evil the over shadows anything even you did."
Shocked at being given this chance Revan quickly accepted.
Smiling in satisfaction, the Force released him from the wall. "Be careful though, this child cannot turn to the dark as you did, should he fall your punishment will return tenfold. However this does not mean I want him trained in the ways of the Jedi Code, while a decent set of guidelines it has become too limiting and will not allow Naruto to do what needs to be done."
"Then how should I train him?" Revan asked confused.
"The people of this world, the shinobi, have good understanding of what power is and how it should be used." The Force said in explanation.
"Are you serious? I have met many shinobi in my time here and some of them have been even more evil than I ever was." Revan stated his confusion having only been compounded.
"The ones of this village understand better than most, they fight for those that are precious to them, but still know when and where to use their power and how to deal with their emotions. For that is where the Jedi of now have failed, they no longer acknowledge their emotions, simply shove them aside so as not to become burdened by them instead of understanding them and embracing them." Pausing to allow what she had said to sink in she continued "You knew it better than most when you were still a Jedi, you embraced your emotions but did not let them rule you."
Nodding his head in thought he said "You know that if he ever meets the Jedi council they will shun him and possibly try to seal his abilities away. And if he were to be trained as shinobi as well, the entire council would still be able to stop him."
"Should they attempt to do so, I will step in." She stated with authority.
Eyes going wide Revan finally understood just how important his host was in her eyes. "So you plan to have him leave this planet?"
"Of course."
"He will need a ship, and the people of this world are still thousands of years from being able to build one with the ability to cross the galaxy."
"When the time comes, I will have ship brought here. Now I must go, the boy's life is in danger and will need the healing abilities of the demon to survive." With that she disappeared leaving him to wonder about how he was so train the boy if he trapped in here.
A moment later his question was answered as his demonic body glowed brightly changing from a giant fox to what he had looked like before complete with his armor and lightsaber, however he noticed that he no longer had the foxes power as that had been stayed within the cage to heal the boy. In that instant he was enveloped in a bright light again and transported to outside of the boy who was rapidly healing now that the villagers had left him to die. When Naruto had finished healing Revan picked him up and walked to the boy's apartment, knowing the way from the boy's memories.
Walking away he realized that his life would never be the same and that the life of this boy was about to change forever.
