Hello, fellow spacers and smugglers. Centurion here, and welcome to a Rwby sci-fi AU fiction. The name of this fiction is Rwby: Battle For Remnant. I was inspired by the fiction Birds of Prey written by a fellow writer: DairyProduceBasedCultLeader. I wanted to write my own Rwby sci-fi AU, so here I am. Some of the chapters will be character-centric. There will be OCs in this story. However, I am accepting OCs, so let me know in the comments or PM me. As usual, please enjoy, but this time, reach for the stars.

A/N: Some of the locations will be of my own creation. Grimm will still exist as well as be ship classes. So get ready for some stuff that will be crazy.

The Beginning of an Arc

The galaxy of Remnant. Full of life and spirit, or at least it used to be as it is currently in turmoil. For the last few centuries, it has been under siege by the evil Grimm Empire. This regime travels to each system stealing resources to build ships and weapons, enslaving millions of people to fuel their war machine, and spreading their regime across the galaxy, killing off whoever tries to resist. Very few have the courage to stand up to the Grimm Empire as it's shadows threaten to consume all of Remnant. However, those same few hold out hope for a light in the darkness...

The planet Geldar in the Mistral system. A partially lush planet, but mainly known for it's rich dust mines, lovely meadows, and towns. A moderate-sized white and yellow ship was flying low on the planet's surface. It seemed to be lugging some kind of tech from another downed ship. The tech was kind of heavy to carry any higher, otherwise the ship would break apart. A few minutes later, the ship made it to Stonewell Town which was bustling in anticipation today due to the ship coming. When the people in the town saw the ship's symbol which was two arcs, their faces lit up in excitement.

"It's the Crocea Mors!" One of the observing people exclaimed happily.

"Jaune must be back with some tech." A second person assumed.

"Or dust." A third person theorized.

"Nah. It's gotta be tech." The second person started to argue. As the two were arguing, the Crocea Mors made it's landing. Once it landed, a bottom compartment opened to reveal not only a little bit inside the ship, but also a 17 year old man with blonde hair, azure blue eyes, and a diagonal scar on his right cheek wearing white and yellow Combat Armor.

"Jaune!" Some of the people cheered. "You're back!"

"Yep, and with some gifts." Jaune smiled. Walking back into his ship for a couple minutes, then walking back out with a hover cart full of all kinds of tech. The tech in the cart included a an Imperial Grimm Scanner from a downed vehicle from the Grimm Empire, A Mistralian Shield Generator, and a 10 stolen Asheron Systems T-54 Blasters. "These gifts are for this town." He smiled.

Suddenly, a boy about the same age as the blonde knight with onyx black hair, cerulean blue and white knight armor, and orange eyes walked out of one of the buildings. "Thank you for such the charitable donation, Jaune." The boy said smirking.

"You're welcome, Lionel." Jaune smirked back. "I'm just helping out the people."

"Holy crap! Are you ever modest." Lionel joked.

"I guess I was raised right." Jaune grinned.

"Right you were, kid." An older person agreed.

Suddenly, everyone heard a increasing sound of multiple engines. "I know that sound." The older person grimaced.

"Grimm Drakes!" Lionel shouted.

"That's my cue to take to the skies." Jaune said sternly. "Lionel, help these people defend the town."

"Of course." Lionel nodded. Jaune nodded back and started running to his ship. Soon however, 10 black streaks suddenly appeared in the clear blue sky. Thankfully, the sun was still out to provide light to see the streaks. Jaune powered up his ship the second he got in and took to the air. When he got high enough, he saw the streaks. "Grimm Drakes. Of course." He said with a dark undertone. "It won't be long before they spot me." Suddenly, he came under blaster fire. "Well, that was sooner than I thought." He began to maneuver around the Grimm Drakes. Back-flipping the Crocea Mors behind two Grimm Drakes, he shot them down before proceeding onto the others, but not before they released individual blobs of black ooze. Jaune's eyes widened as he knew what those blobs meant. He returned his attention to the Grimm Drakes. Three other Grimm Drakes released their own black ooze blobs before being destroyed. Two Grimm Drakes got behind Jaune and fired at him, but he evaded the shots by tilting his ship to a vertical position. Then, he pressed a blue button and a secret hatch on the underside opened up, revealing a white and yellow Argus Industries B-6 Eliminator. The Eliminator fired at the two Grimm Drakes behind Jaune. However, he got hit on the topside, rocking the ship a tiny bit. His face turned serious again and he directed his fire at the remaining Grimm Drakes using all his ship's weapons. Soon enough, they were all down. "Whew. Glad that's taken care of. Now to head back to the ground." With that, he started descending back to the planet's surface.

Meamwhile, on the ground, the five black ooze blobs began taking shape into Beowolves which began moving towards the town. Luckily, Lionel was on the ground with the people. "Alright, everybody. Remember the plan." He whispered to the people with blasters. Within minutes, the five Beowolves were in Stonewell, searching around for potential victims. All five of them saw Lionel standing directly in front of them with his sword which was also cerulean blue and white drawn. The Beowolves growled at Lionel as if to try and scare him away, but he stood his ground. "Come and get me." He taunted. The Beowolf at the front when suddenly a T-54 Blaster shot hit the Beowolf, redirecting it's attention which gave Lionel the opening he needed to jump up and slice the Grimm's head off. The other Beowolves seemed a little confused as to what had just happened when more blaster shots appeared from all over the town, hitting them all over their bodies. Lionel proceeded to slash at them while they were distracted with the blaster fire. Soon, they were all down. The people cheered just as Jaune made it back. Once he landed, he ran to see if everyone was alright, and sighed in relief when he saw that everyone was.

"You okay, Lionel?" Jaune asked.

"You know it, Jaune. Besides, I needed the practice." Lionel grinned.

"Sure you did. Meanwhile, I was dealing with those Grimm Drakes up in the air." Jaune grinned back.

The people of Stonewell began emerging out of their hiding places and cheered. "Thank you, Jaune. Lionel." The older person bowed. Jaune and Lionel looked around and saw everyone smiling at them. "Jaune. We know you have to leave. Just know that you'll always have a place with us." Jaune began tearing up a little.

"Thank you, everyone." Jaune sniffled. "You guys are great. I promise that I will be back. Although, will you people be okay when I'm gone?"

"I believe we'll be fine, Jaune." A mother said smiling at the blonde knight. Jaune was still sniffling and tearing up when out of the corner of his eye did he see Lionel snickering. "What?"

"Well, aren't you just a big softie." Lionel playfully taunted.

"Shut up, will you." Jaune slightly nudged the fellow knight. "Well, this is goodbye, Lionel. May we meet again someday." He said holding out his hand.

"I'll hold you to that." Lionel smirked grabbing Jaune's hand with his own. Together, they said "Knights Forever." With that, Jaune went to his ship, powered up, and took off into space, leaving Stonewell Town behind. There were good people in that town. Jaune was holding out hope that he would see them again, but rarely anything is certain. As he left Geldar's atmosphere, he was entering the dance of stars and other lights in the vastness of space. This was merely the start of his grand adventure. However, he was a knight, and knights had honor to uphold, and Jaune would aim to uphold his honor to the highest he could by helping people that he could to the very best of his ability.

Hello, everyone. Here is not a chapter, but more so a prologue to this story. This is kinda like a character intro to this adventure. The planet Geldar in the Mistral system is a planet of my own creation. In this chapter, we saw Jaune Arc in his ship: Crocea Mors helping out a small town. A warning though, some of the actual characters will be a little OOC, but it's needed a little for this AU. Jaune and Lionel make a promise to meet again someday. I'm sorry if I'm not good at writing these kinds of battle scenes, but I'll get better with practice. If anyone has ideas about characters, locations, weapons, grimm, please let me know in the comments or PM me.

Geldar is a partially lush planet with a couple forests that hold strange wildlife. However, some of the planet's wildlife can live in the towns, meadows, and even dust mines. One form of wildlife is the Stonwell Scorpion. Even one drop of the Stonewell Scorpion's venom can paralyze a person for three days. The people have to be careful with the dust mines because dust is targeted by the Grimm Empire.

The Grimm Drakes are scouts/fighters of the Grimm Empire. They're swift and sweep areas for enemies of the imperial regime. They can also release individual blobs of black ooze that take shape into Grimm.

Ah, the Argus Industries B-6 Eliminator from Argus in the Mistral system. It is a semi-automatic blaster gun that can damage even some medium sized ships. No other data on Argus is available at this time.

The Asheron Systems T-54 Blaster is a weapon made by Asheron Systems from the planet Asheron. The system where Asheron resides is unknown. The blaster is a standard weapon used in the Grimm Empire. More about Asheron will be revealed later as no other data is available.

I appreciate support for this fiction as I do with all of my fictions. This is my very first sci-fi AU, so we'll see how this goes. Which character intro do you want to see next?
