Chapter 1: Fall of an Empire; Birth of a Cycle

-X-

It had been eighty years since Uzumaki Naruto and Uchiha Sasuke had recreated Arashi no Kuni, the country which had played host to Amegakure, into Chouwa no Kuni.

About five years ago, Ino had sensed a disturbance farther than anyone had ever been, high above the clouds, even past the moon which housed the Jubi and their far off attempt at terraforming Aeia. And the threat this entity posed was far greater than any before in terms of pure malevolence. All agreed that they needed to determine what – if any – steps they needed to take to ensure their safety. The creatures searching for them either enthralled or killed every race they found, and the Chakrans had proven they could not be controlled.

"If it's any consolation, they don't seem to know exactly where we are," Yamanaka Ino, their Spiritual Diviner, had said after they had convened in Oversight Tower, the central and tallest tower in Chouwa no Kuni. The blonde wore a simple yet elegant lengthy white kimono with sakura petals along the right side in homage to her late friend, while a pale purple obi finished the priestess' outfit.

As a Diviner, Ino's thoughts were focused skyward or, more specifically, star-ward. Her duty was to study how the movements of stars, planets, and a plethora of other astral objects affected not only each other, but their relationship with Shinobi (for lack of a better term) and the many factors of Ninshuu.

Hyuuga Hanabi, the Head of Elemental Harmony, nodded along with the blonde priestess' words. "It's not Gakure they are specifically targeting... Simply put, they are looking throughout the entire Nebulae to find us. If they knew exactly where we were, their disturbance of our ninshuu would be much greater."

The brunette's job was to determine and catalogue how different factors either disrupted or enhanced a Shinobi's connection with their inner chakras, as well as their resonance with the chakras around them. To help with this, many devices were on her arms, covered by a loose lavender knee-length kimono. The yin-yang symbol rested firmly between her shoulder blades.

"We can't let the public know; there would be riots in the streets," Sabaku no Gaara, Head of Village Security, added. "Yes, we should determine what steps we need to take to ensure our safety, but the civilians, and the Shinobi, cannot know. Not until we know..."

The red-head was simply responsible for defending the peace of the Village of Harmony. Whether the threats were within the walls or just outside them didn't matter, how he handled it was up to his discretion.

Sarutobi Konohamaru, the Head of Elemental Security, spoke up next. "And this should stay between us. Don't even tell the Gotei 9. Their fear of the unknown would disrupt their chakra flow. Better for them to have an enemy to focus on, one that they can see, rather than some mysterious force beyond our sphere of influence."

Konohamaru's job was to ensure the elements themselves were being treated properly. This included such things as using water properly and, more importantly, preventing emotions such as fear as much as possible in order to not affect Senjutsu in such a negative way. Each branch of the Gotei 9 focused on a specific aspect. For example, the 2nd Division focused on the element of Fire, while the 9th Division focused on emotions such as fear, hatred, and vengeance. His outfit was similar to what Naruto wore at 16, though colored forest green and navy blue and sporting a three-foot-long blue scarf.

Uchiha Sarada – Sasuke's daughter and the Head of Inner Peace – nodded along with Konohamaru. Her outfit was her mother's as a Chunin, colored like her father's as a Genin. The difference was the fact that the circles of the Haruno Clan were replaced by the swirls of the Uzumaki. "It's only been 15 years since the 6th War… People are still on edge. When promoting peace, prepare for war… A significant enough trigger, and it's possible this will end the same way as the 6th War." Sarada worked closely with Gaara, her Sharingan discerning auras, and therefore intentions. She could see the nervousness and distrust most still held for each other.

Aburame Shino, the Lead Strategist, steepled his fingers, obscuring the bottom half of his face moreso than his grey trench coat. "Given their current course, what time frame are we looking at. Longer is, obviously, better. Also, a more thorough anatomy of the enemy would be benificial."

Taking the Aburame's cue, Ino placed her hands in her lap, assuming a pose similar to her former teammate Shikamaru. "Sasuke," she said simply, and her husband stood and placed his hand on top of her head, his Eternal Mangekyou Sharingan and Eye of Kaguya working in tandem to watch for any discrepancies in her control. At the same time, Hanabi assumed the same pose in front of Ino, their knees touching. Naruto did the same as Sasuke to his own wife, his Rinnegan also vigilant.

The jutsu had originally been used as a sensor for less-than-noble intentions in the Elemental Nations. Ino sensed it, Hanabi pin-pointed it, Naruto used his perfected Hiraishin, while Sasuke and any reinforcements came after he placed the seal for the original Hiraishin. This time, however, Naruto and Sasuke were focusing their wives' jutsu to see farther than they had ever tried.

Hanabi used Ino's sense to focus her attention, and Naruto's Rinnegan to hone her Byakugan into as fine a cone as possible. Even Sasuke's Sharingan would be hard-pressed to differentiate it from a simple line had it been visible, though for now it was tasked with narrowing the brunette's search.

After a few tense minutes of simply adding more chakra to increase her vision's range, Hanabi saw... something. Even at the edge of their star cluster, the end of her visual cone was no wider than the wheel of a small cart. Converting some of her chakra to its water nature to give herself a panoramic view, what she saw made her gasp.

Naruto, Sasuke, and Ino, who were linked to Hanabi, also saw what she saw. Naruto and Sasuke tensed, a barely noticeable reaction for non-shinobi, instinctively knowing that this threat was far greater than that of Uchiha Madara. Ino, however, wasn't as adept at hiding sudden strong emotions, and gasped as audibly as Hanabi.

Nevertheless, their teachings of Ninshuu focused on practicing diplomacy before anything else, so despite their misgivings, Naruto and Sasuke wordlessly decided to take the long trip and, should something happen, they would simply Hiraishin away and prepare for the worst.

"What's wrong, Nii-san?" Konohamaru asked his long-time mentor, obviously noticing the tenseness of his Sensei. Even after a century of teaching, Naruto always found something new for the former Nanadaime Hokage to learn.

"Kono," the blonde hissed, a clenched fist held by his still kneeling wife, "what is our fastest spaceship?"

"The Kokuo-class," Shino replied before Konohamaru could answer. "They are the only ships equipped to handle both Jikakuan and Jinton chakras as of right now. They finished production right before this meeting was called."

"And does one have a seal yet?" Naruto asked. One of the first rules that Naruto and Sasuke decided on was that any moving vehicle and any building in Chouwa no Kuni was to be equipped with a Hiraishin seal somewhere on or in it.

In the beginning, when crime still existed enough for there to be gangs, they would cut the seal out of the building's wall, but not destroy it since Naruto would immediately feel that. Naruto didn't necessarily need the seal, it just took the risk out of him ending up halfway in a wall. On non-urban battlefields this wasn't possible since he could feel the nature chakra in trees and rock formations, but steel, glass, concrete, and bricks were processed, effectively killing the chakra in them.

This was why most buildings in Chouwa no Kuni were cut out of unprocessed mineral blocks, the most common being granite or marble. Chakra Rods were then used to not only anchor the building to the ground, but also help with the circulation of nature chakra. Basic amenities such as heating, cooling, running water, and electricity were all taken care of with Fuinjutsu powered by nature chakra.

Occasionally, Naruto would use the Hiraishin seal to either check the seals' history(distance traveled as well as if they were used by anyone else), or to cut down on the time it took for him to meditate and find a new location.

"It does," Konohamaru said. "Had 'em stitch it in the seat covers," he added proudly.

Naruto smiled at his long-time protege as he and Sasuke stood apart from the others. In some ways – most notably the Summoning Contract, the young-looking Sarutobi had unquestionably surpassed him. After the death of Gamakichi at the hands of Kaguya, Naruto and the Toads had had a falling out due to the blonde's inability to gather Nature chakra because of his tumultuous emotions, and the Toads – most notably Ma, Pa, and Gamaken – demoting him due to this. After all, what kind of Gama Sennin couldn't perform Senjutsu?

He could now, but the damage was done, and Naruto's name was burned from the scroll.

"Very good, Kono," the blonde said genuinely. "We'll need all the help we can get if we cannot settle this peacefully... You've come far since you first came tripping into Jiji's office."

Konohamaru huffed in indignation. "You tripped me, Naruto-nii," he grumbled, though a small smile tugged at the corners of his mouth. For his part, Naruto waved his protege away as he focused on the N.D.F.(Ninjato Defense Fleet) Kokuo.

Gakure, the Chakrans' home planet, was an idyllic garden world ever since the end of the 6th Shinobi World War. They, especially those who lived in Chouwa pre-Nation disbandment, had experienced a period of peace unlike any before, considering their status as a warrior race. However, they had known about the creatures they were about to meet for almost as long, and created Ninjato as a failsafe in case talks went south, with them or any other race.

Naruto and Sasuke wished to see peace for as long as they lived, and hopefully after, and to end the cycle of hatred. They could do neither if they were dead or slaves.

"Yare, yare... Whatever helps you sleep at night."

Ino and Hanabi, knowing what their husbands were planning, stood up and kissed Sasuke and Naruto, respectively.

"I love you," Ino said sincerely, holding Sasuke's head so he looked into her eyes.

"Come back to me," Hanabi said, mirroring the blonde with her own husband and finishing her thought.

"I love you, too/Promise of a lifetime," the two lifelong friends replied.

krrrrmmmmm...

And with a sound like rolling thunder and a flash like lightening, Naruto and Sasuke were gone, preparing for their encounter with the beings who sought them out. From what their observations of the wider galaxy had revealed, the creatures had named themselves Leviathans, and either controlled new sentient races they found, or exterminated the ones they couldn't.

It was by pure chance that the Chakrans hadn't been discovered yet; Kaguya, the Gas Giant between them and their sun Amaterasu, constantly radiated chakra and hid not only their solar system, but the entire Rosetta Nebula from all but visual observation.

"Their diplomatic skills are well above average," Shino supplied, trying to placate the two women. "At the very least, they will return."

"Their bond will carry them through this ordeal," Garra said in as compassionate a voice he could muster. "We must simply wait for them."

"Don't count out Tou-san and Sensei just yet, Kono-koi," Sarada teased her husband. After all, she, Hanabi, and Konohamaru had been a Genin squad under Naruto's tutelage.

Then all eyes turned to Konohamaru, who had made his way over to the South Window, tracking the Kokuo's chakra-laced trail against the starry night sky. The ring-shaped Chakra Propulsion System was glowing brighter and spinning faster than it was ever designed to; the perks of having one teammate with a Sharingan and the other with the chakra capacity to rival all the Biju combined, most assumed.

"...just gotta wait for 'em..."

A clenched fist at his side raised, ready to strike at whatever next caught his ire. However, with great difficulty, his fingers splayed, resting on the cool glass. "Make it back, Nii-chan..."

Naruto and Sasuke would not be back for seven years... And in those seven years, many new constructs were envisioned, such as the Geranium and the Galactic Chakra Transference Array, though neither were built. Bunkers were also created on Laban in secret, just in case the Leviathans were as bad as Ino felt them to be; having never tested it on a non-Chakran, she wasn't sure if her aura reading could be trusted. And with their lack of Chakra, Hanabi and Sarada couldn't get an accurate read on their feelings, either.

When Naruto and Sasuke did finally return, it was with grave news. The Leviathans believed themselves to be the first and only "Apex Race", and that every other race should be subservient to them. When the two refused, stating that the Chakrans wished to be free, it sparked a war that would last millenia and span the entire galaxy, not that either could believe the cost such an offensive could carry.

Hundreds of billions of Chakrans lived and died on a dozen systems and dozens of planets, knowing nothing but the threat of the Leviathans and their indoctrinated warriors, the Kaiju. Killing the Kaiju meant making a planet toxic, but allowing them to live meant they would slaughter every Chakran to the last. The only option the Chakrans had was to evacuate the planets, and then use those planets against the Leviathans if possible, killing two aliens with one giant, previously orbiting stone.

Many new weapons were also created, such as Naruto's Crimson Striker and Sasuke's Samurai Spirit. Despite being advocates of peace, they were not ones to sit back while a race bent on eradicating them was loose on the galaxy.

However, the Chakrans quickly realized they were outnumbered. Despite being more advanced technologically, their proficiency at subterfuge, and centuries of warfare tactics, the sheer number of Leviathans and their thrall races was simply overwhelming.

The Chakrans also created the Shinigami, autonomous robotic Leviathan-shaped constructs. Meant to be able to get in close to other Leviathans and their slave races, it proved an effective strategy. Naruto and one such Shinigami named Harbinger were on the front lines of many battles, but usually caused massive collateral damage.

After decimating the slave races and forcing the Leviathans back to their home planet, Shinigami were revealed to the public, as only members of Ninjato had seen them previously. But the reveal proved to be the beginning of the end, as the Chakran civilians feared the Shinigami, and tried many times to destroy them, albeit unsuccessfully. The Shinigami retaliated, and reasoned the Chakrans were a threat to themselves with their inherent warrior-like tendecies.

Thus began the first Reaping, with the Shinigamis' own creators, the Chakrans, as the first harvest.

-X-

Boo-yah! Seems awesome, right? RIGHT? The Chakrans created the Reapers, or should I say Shinigami! The next chapter will be a timeskip to far in the future, a handful of years before ME1. This story will cover all three games, and have a much better ending(not that hard, BioWare...). The Galactic War(Chakran&Shinigami/Leviathan&Slaves) and Shinigami War(Chakran/Shinigami) will be shown in flashbacks, as well as the Chakrans' own advancement from after the 4th Shinobi War to Naruto trying to help the new races in preparing for the Shinigami. Lemme know what you think! Main Pairings will be Naruto/Tali(slow-burn) and Fem!Shep/Garrus(much quicker), among others. And believe me, the other chapters will be around 4k to 5k words apiece. This was just to showcase the past. It'll come back, though...
