(A/N) So I recently got into playing Warhammer 40k and got real interested in the Blood Angels and after reading The Lost Sons by OculilImperator, I decided to have my own go at a Warhammer/RWBY crossover.

The basis of this story is that Remnant is under the Imperium's rule but when they sent the Imperial Guard to colonize it, they people on Remnant at that time refused to simply bow down and after negotiation, agreed to leave Remnant in the Imperium, but they were to rule as they pleased so long as it caused no issue for the rest of the Imperium. The Blood Angels were sent to Remnant along with the Adeptus Mechanicus to use make some use of the materials Remnant had.

The Arc family after the Great War decided to join the Blood Angels, and during the time Ozpin, Glynda, Oobleck, Port, and STRQ were students, There were Dante and Lemartes Arc; Twin brothers of the Arc Family and sons of Sanguinius himself. After their time in Beacon(which I might make a separate story on later), they joined the Blood Angels where, as known, Lemartes falls to the Black Rage and Dante becomes Chapter Master.

The main focus of this story is on Jaune, however. After Jaune is shunned by the students of Beacon for his falsified transcripts, he decides to leave Beacon academy on his own. After traveling through the Emerald Forest in his attempt to leave Beacon, he is severely injured and is found by a Blood Angels Scout Squad sent to patrol the forest. Jaune is then sent to the Blood Angel's base of operations to be tended and have the implants placed for him to become a Space Marine.

These events will be better explained as the story progresses, and Jaune learns more about the Universe and tries to hold back the Red Thirst/Black Rage.

Anyways, I hope you enjoy the story and let's see if I can make this idea work.


Location: Blood Angels Base, Medical Wing.

Belisarius Cawl monitors Jaune's body as the implants are being placed and secured for the upgrades. As this is happening, Commander Dante Arc walks into the room with his signature golden armor, the face on his mask remaining as still as ever, and betraying no emotion of the man underneath. "

How is he?" Dante asks, nodding his head towards the boy in the medical room being operated on.

Belisarius ponders his answer for a moment before speaking. "He is well. The procedure is progressing as planned. No issues have come up as of yet." Belisarius replied with his robotic voice due to the extensive modifications done over the centuries to make him more machine than man, leaving almost no trace of his human origin.

Dante nods in reply before turning to walk out of the room. "Continue as planned, notify me when he awakens, We need to begin his training as soon as he can."

Belisarius turns away from Dante to face Jaune again. "Understood, Chapter Master." Belisarius replies before returning to his work.

Outside the room, Dante calls for a transport to Beacon Academy. His Sanguinary Guard at his side as he makes his way to the Stormraven-Class Gunship that will be transporting him to Beacon.


Location: Beacon Academy, Headmaster's Office

Ozpin stands from his chair to look out the window of his office. Looking out to the scenery before him, he notices a golden aircraft flying towards the Academy. He immediately notified Glynda Goodwitch to greet them at the Airdock and escort them to his office. Sitting back down at his desk, he sips from his ever-present mug before sighing and preparing for the meeting to come.

Ozpin had been expecting this meeting ever since the discovery of Jaune's injured body being found in the Emerald Forest one week after his disappearance from Beacon Academy. Ever since it was publicly revealed that Jaune Arc used false transcripts to join Beacon, he had been outcast by the student populous, even being abandoned by his own team and Team RWBY.

He just hoped that it wouldn't have happened so soon. With the issue of the Maidens, and the Darkness growing, the last thing Ozpin needed was a problem with the Blood Angels. Rubbing his forehead, he sips from his coffee once more and awaits the arrival of whoever was sent from the Blood Angels to meet with him.


Location: Beacon Airdock

Glynda stood at the Airdock waiting for the Golden ship to land. Once it landed, four tall men, clad in golden armor resembling angels with pure white wings walked off the airship in their formation, holding their great Glaives Encarmine in their hands.

After the stepped off the ship, they took their position on either side of the entrance to the ship, two on each side saluting. From the ship stepped off a man in similar armor, but this soldier's armor had far more wear-and-tear from the decades of use, but still had its glorious, white wings. The helmet also resembled the face of their great Primarch, Sanguinus.

The man in the middle continued to walk forward, with the other four soldiers following behind him on either side. They stood in front of Glynda and she had to repress a shudder at the sheer sight of them due to their intimidating height and prowess.

The man in the front saluted to Glynda before speaking. "I am here to speak with Headmaster Ozpin. We have quite a bit to talk about." the armored man said in his calm, but mature voice that Glynda did not fully recognize.

"Yes, follow me." She quickly said before turning to lead them to Ozpin's office. The five men following behind her without another word. As they walked through the halls of the academy, students stopped to see the five golden-clad men following the headmistress in awe at the sight before them.

Blood angels are known by all in Remnant, as students learn about them in the Hunstmen academies, but it is a rare sight to see them, let alone the highly-honored Sanguinary Guard.

After some time walking, they arrived at the elevator that would lift them to the Headmaster's office.


Location: Beacon Academy, Headmaster's Office

The door to Ozpin's office opens as six figures walk into the room and near the desk. Glynda Goodwitch takes her place next to the Headmaster's desk while the four men in Angel-like armor stand at the door, the man in the more decorated armor settles to stand in front of the desk.

Ozpin takes a sip from his mug and looks up to face the golden-clad man in the middle of the group. "Dante, a pleasure to see you again. It has been quite some time." Ozpin calmly says to the man standing in front of him.

The man now identified as Dante takes off his helmet and places it on the desk before looking up to face Ozpin with a glare.

"Let's skip the pleasantries. You know why I'm here." Commander Dante states brusquely.

"I am. And I want you to know that I did not intend for this to happen. None of the staff here at Beacon expected him to leave the academy on his own, let alone into the Emerald Forest in the middle of the night." Ozpin tried to reason.

Dante scoffed. "And nobody was patrolling the academy grounds, the forest, or had any cameras that were actively monitored?" He asked with a stern look.

Ozpin thought for a moment about how to answer the question, know that the wrong response could make the situation worse than it already was.

Noticing the lack of reply, Dante stood straight and looked down at Ozpin. "Considering how calculating you are, always wanting to have every variable under your sight and control, I would expect more. And this monumental failure on both your part, and the entire Beacon staff caused my son to nearly die!" Dante's voice raised as the continued the sentence, slamming his hand on the desk at the final part, causing a dent and spiderweb cracks to form.

Both Ozpin, Glynda, and the four Sanguinary Guardsmen flinched as the sound of Commander Dante's hand hitting the desk. Glynda was shocked but moved forward towards Dante to be in range if she needed to strike him down, but before she could, Ozpin held a hand up to stop her.

"As soon as we realized that Mr. Arc was missing, we sent out search parties to locate him and return him to Beacon as quickly and efficiently as possible. We did not just sit back and let fate take its course." Ozpin attempted to explain to an infuriated Dante.

Dante slammed his hand on the desk once more and got in Ozpin's face before shouting. "WELL YOUR BEST WASN'T GOOD ENOUGH. MY SON NEARLY DIED BECAUSE OF YOUR INCOMPETENCE AND INABILITY TO CONTROL YOUR STUDENTS, AS WELL AS YOUR INABILITY TO PROPERLY OVERSEE ALL AREAS OF THE ACADEMY!"

Dante inhaled deeply before sharply exhaling. "Jaune is being implanted as we speak. Within the next week he will begin his Space Marine training."

Glynda gasped in shock while Ozpin's eyes widened at the revelation. Glynda immediately stomped up to Dante before going off on a tirade.

"That is inhumane! How could you even possibly consider forcing such grievous modifications onto ANYBODY, let alone a CHILD!" Glynda begins to shout at Dante.

"This is wrong in every way, Jaune should be-" Glynda was cut off before she could continue by Dante turning to face her.

"Jaune should be where I place him, or where he chooses to be. You as well as all of Beacon have proven to be incapable of controlling your students, so how can I expect for you to be able to train him to a point of competence? Jaune will undergo training with Astorath and Brother Corbulo until I deem fit. Once that it over, he will return to Beacon to complete his training under careful watch from my own chosen Chaplain. There is no debate on this." Commander Dante gives his final verdict before grabbing his helmet and placing it on, then turning to leave the room.

"Wait! Dante, please reconsider this. It is a highly dangerous choice, Jaune is not ready for that kind of training." Ozpin tried to reason with Dante to prevent what was coming.

Commander Dante ignored Ozpin, stepping into the elevator, followed by his Sanguinary Guard as the descended back to ground level. The five golden-clad men then made their way back to their ship to return to their base of operations.


Location: Unknown

Astorath was moving about his hidden reclusiam attending to the work he has as the High Chaplain of the Blood Angels. Outside of his reclusiam are the Erelim, dark counterparts of the great Sanguinary Guard.

The erelim wear the same armor as their holy bretheren, but the armor of the Erelim shows no special markings other than the Blood Angels symbol on their shoulders. The entirety of their armor is a dark black, as are their wings. their eyes an eternally glowing dark crimson. The erelim stand guard just outside of the High Chaplain's hidden reclusiam, protecting it as the man within tends to the work that must be done. The location of this reclusiam is known to none beside Astorath himself and the Chapter Masters of the Blood Angels and their Successor Chapters.

While working, Astorath felt the beginning of the Black Rage's effects on a new Blood Angels brother. He knew this was from the gene-seed being implanted, but was still worried as he knew who was receiving this new gene-seed, along with the dark flaw that follows.

This though reminded him of the man that sleeps, only awoken when needed for war, to lead the Death Company; men lost to the Black Rage's effects and turned to nothing more than mindless killers to their final redemption and reward for their great sacrifices.

This man was Lemartes Arc, a valiant soldier who fell to the Black Rage, but was able to hold back its madness and maintain his sanity. When Astorath was about to give him the Emperor's Peace, Lemartes had refused it, stating that he still had a purpose on this world. He demanded to live so that he could continue to slay the Emperor's enemies. Astorath had regained a hope he had long ago lost that maybe the Blood Angels could overcome the great flaw known as the Black Rage.

Astorath immediately continued working with renewed fervor at the tasks at hand. He also was prepared for Dante's arrival to discuss the training of his son, the young Jaune Arc.


Location: Blood Angels Base, Halls of the Damned

In the halls, screams could be heard from the damned soldiers inside. Lost to the Black Rage, screaming from the torment it wreaks upon their souls, being forced to see the final moments of their great Primarch, Sanguinius before he was slain by the traitorous Primarch, Horus.

Far in the back of the Halls, in a single cell, is a Chaplain. This Chaplain holds great power in both his physical prowess, and his mental fortitude. Lemartes Arc rests in stasis, waiting to be awoken for the next bloody battle where he will lead his Death Company Brothers to the glorious deaths they deserve for the sacrifices they have made for the good of the Galaxy.

Lemartes was awoken from his Stasis, and he sat in the single bench at the back of him cell, awaiting for the High Chaplain, Astorath, to send him to the next great conflict. While waiting, stared at his hand, the same hands that have brought death to countless Orkz, Traitorous Heretics, Xenos, and Monsters of the Chaos. He clenched his fists in anticipation for what was to come, and prayed to the Emperor that he would be able to stop whatever was coming.


Location: Blood Angels Base, Medical Wing

About 14 hours have passed since the completion of Jaune Arc's implantation of the artificial organs and other modifications of the Space Marines. Jaune lied in the bed of the Medical bay, resting as the effects of the anesthetics wear off. In the observation room, Belisarius stood, watching over the Young Arc, with his mechanical parts quietly whirring as they always do, moving slightly to and fro every so often as they always have, praying to both the Omnissiah and the Emperor that the boy has fate on his side for once. Cawl then turns and activates his communications systems that he implanted into himself long ago during his transformation to a Mechanical Being and notifies Commander Dante that the modification have been completed, and the boy should awaken soon.


Location: Blood Angels Base, Medical Wing.

Time Lapse: 24 Hours.

Jaune's eyes open slowly, the bright, blinding lights of the Medical Wing shining into his eyes, causing him to squint and attempt to cover his eyes. As he regains his consciousness, Jaune notices that he can hear far better than before, hearing the smallest whirs of the machinery in the room ever so clearly. Moving his hands away from his eyes, he notices that his vision is also much clearer, and more detailed than it used to be. Looking down at his body, he also notices that he has grown quite a bit from what he remembers.

Hearing a sound come from the door, he jerks his head to look at the entryway to the room he is in, and notices a man with Golden Armor walk in. Behind this man, is a being that seems to be completely robotic, the being was large, almost entirely mechanical, and had multiple robotic tendrils with claws, lights, and other tools protruding from its body.

The man clad in gold looks at Jaune before speaking. "Come, We have much to prepare you for, Soldier."


Commander Dante Arc: Chapter Master of the Blood Angels, Jaune Arc's father.

Lemartes Arc: Chaplain of the Death Company, Jaune Arc's Uncle, Dante Arc's brother.

Astorath the Grim: High Chaplain of the Blood Angels, given the duty of slaying Death Company Brothers who survive a battle to give them the peace they have earned.

Belisarius Cawl: High Priest of the Adeptus Mechanicus, and in charge of the functions of the Adeptus Mechanicus on Remnant.

Black Rage: A flaw in the Gene-Seed of the Blood Angels, causing soldiers of this Chapter and all its Successor Chapters to have visions of their Great Primarch, Sanguinius in his final moments before his death, sending the soldier into a crazed madness, viewing everyone around him except for his fellow Blood Angels as soldiers of Horus, the great Traitor. Those who fall to the Black Rage in the field are stripped of all weapons except their Chainsword, their armor is painted black, and they are sent to slay as many enemies as possible before their death. The Death Company's rage makes them able to shrug off wounds that would leave any other Space Marine down. The only way to stop the Death Company is to slay them, or have a Chaplain such as Lemartes or Astorath guide their rage.

Blood Angels: Chapter of the Space Marines stationed on Remnant to guard it and the Adeptus Mechanicus that operate on this planet.

Adeptus Mechanicus: Beings who have long forgone their human forms for mechanically superior bodies through centuries of modificiation, these being are more machine than man, tasked with creating the armament of the Imperium, as well as producing more Space Marines with the implants required.

(A/N) I hope this goes well. I've had this idea in mind for months and finally decided to act on it. Please R&R, and if you have any questions or advice/recommendations, feel free to PM me.

This story obviously deviates quite greatly from the actual Lore, but it's something I wanted to try out. The idea for this story is for Jaune to develop as a Space Marine, while trying to hold back the Black Rage, as well as overcome the pain and hatred for the people he had once called friends while a dark enemy comes to Remnant, seeking its destruction.
