Prologue:

001 M42

Segmentium Tempestus

Imperial Agriworld: New Helse

The sounds of bolter fire surrounds me, the dull thudding of endless war. The pathetic and blind Death Guard are a better distraction than Ahriman predicted. It's far better to lose a hundred plagued Astartes than a single Rubicae, it's also a mercy to kill those who have lost their minds and bodies to the Ruinous Powers. "Pathetic are they not brothers?" I mindlessly asked my Rubicae, they would not answer, and their silence always saddened me; I knew each of them before they turned to dust. We fought side by side on Prospero, a few since the dawn of the crusade.

"Be one with Nurgle sorcerer!" An almost drowning like voice yelled. Before I turned my bolt pistol on the traitor. Sending a high explosive round towards the foe, I subconsciously sent some of my power into the round allowing it to burn into the disgusting form of the marine. Yet another mercy killing. I know my Rubicae continue their task flawlessly, sending round after round into the foe, with accuracy that would terrify even the finest of sharpshooters. Every once and a while a traitor would surge forward only to be cut down by one of my brother's power khopesh in a single fluid motion. The efficiency of a Rubric Marine terrifies even me sometimes. According to some of my brothers this is due to them only regaining some of their former selves in combat, if this is the truth, than it only saddens me more so, to not feel the joys after a fight is done. They would only feel life in endless war.

+Outcast, do you still live?+ The familiar sounds in the back of my mind cooed once again.

+Yes brother, I still live. I cannot say the same for many of these traitors.+ I replied with but a thought.

+Good, Ahriman approaches the Black Library, we are close. I can feel the legion returning to its' former glory! You have done well Outcast, Ahriman thanks you for your dedication as well.+

Outcast, I'm unsure why exactly I'm titled that by my Brothers. Was it because I chose to work alone after Prospero, was it due to my solitary study habits before the fall, or was it due to my place of origin was not like the rest of the legion? Perhaps it's all of these factors. Regardless, Ahriman thanking me himself filled my hearts with pride.

+Inform our lord that thanks will not be necessary, I am eager to stand alongside my brothers yet again, at that point I shall be thanking him.+ I merely stated the truth of my thoughts.

+You always were humble brother, but we would not be in the webway if not for you.+ A third familiar voice joined our psychic conversation.

+Lord Ahriman?+ I hastily inquired.

+You no longer need to hold the webway gate, you, and your Rubricae should leave that world to its fate. We shall meet again a legion renewed.+

+At once, we shall meet once we show the universe that we are masters of our own fate. Until then, I wish you luck my lord.+

"Let us leave this place brothers." The Rubric Marines fell back in orderly perfection that would make the sons of Guilliman, and Fulgrim look like PDF conscripts. Never taking their bolters off the enemy, and the wailing sound of a soulreaper cannon ending the lives of many Plague Marines in short notice. Once my brothers closed ranks I analyzed the situation. All around us we face Nurgles chosen, but if we advance south we could puncture their wretched lines. The only problem is we would face ranks upon ranks of guardsmen. But that was not the primary problem, we would also face a few Astartes chapters, mostly Blood Angels, and Black Templars. However they pale in comparison to the true foe, the Vlka Fenryka, the bastards of Fenris, the damnable Space Wolves. I don't fear them, by the Ocean I would end their pathetic savage lives with a thought, and great fury, but something tells me they are here because of rumors of the XV legion, so they would no doubt be hunting the Enlighted sons of Magnus.

I sighed "Nothing is ever easy in this universe." I needed somewhere safe in order to perform the ritual to shift us from this world to the rally point, and with the Wolves hunting us, no doubt with a Wolf Priest. By the Ocean even a child psyker could see me perform the ritual. Perhaps with luck, and skill we could penetrate the Death Guard lines.

My trail of thought was interrupted by a bolt round thundering past my head. I turned to see eight perhaps ten Plague Marines. My Rubicae could not fire upon these threats without exposing themselves.

"It seems not all of you are fools, I applaud your initiative!" I yelled at the stubborn Death Guard whilst taking out a boxy sidearm. A loud whining choom could be heard, and a red beam could be seen. Upon making contact with the diseased marine his pustules exploded with enough heat to burn through his nearby comrades' armor, but that was only the start. I heard the Death Guard laugh, as the poor pox filled marine was laughing as his flesh inside his armor boiled away, even those 'blessed' by Nurgle could not bear the damage of Volkite Serpenta. Very few Astartes have seen a Volkite weapon in this age, anyone in the Crusade grows immune to the effects of these weapons on foes, and rarely on their brothers. The flanking Plague Marines must have been five hundred years old, and formed a bond as strong as ceramite, but due to their young age they've never seen a weapon capable of such a feat. Killing one of their brothers and wounding two others in a single shot. This no doubt stunned them like many younger marines, as the analyzed the situation at the speed only possible by an Astartes. By the time they processed what happening I had turned my Serpenta onto another one. The beam cut into his armor, though he did not scream like most marines, his exploding flesh being shot into the air, burning through the maggot infested skull of an unhelmed comrade. The remaining marines charged.

"Come you worthless dogs, I'll show you true might!" I turned my Serpenta to another marine, the beam cutting into his neck joint. I turned my staff to the others, a weapon of exquisite design, while many of my brothers prefer sigils to enhance their connection to the Ocean I preferred a redesign of the legendary Custodes Guardian Spear. That would be until the daemon hunters of the Imperium emerged that a weapon so similar would appear. I also found them ironic, psykers after Nikea, and wielding weapons like the one I have. I sent a wave of psychic energy to the blade, and with all my might sliced into the horrible armor of the traitor. Before burning the newly exposed flesh with another thought. The few that remained were cut down by one of my Rubricae.

"Let us leave now my brothers!" I decided to do something the Wolves would not expect, we would head north. Pierce the Death Guard lines, and the Imperial zealot lines. Perform the ritual, and rejoin a legion anew. It's the best plan that I can devise, but perhaps we will simply face our deaths. I hate hoping that Tzeentch would find it amusing that I live, but sometimes it's needed. So we marched through once lush fields of crops, now blighted, and bombarded wasteland. Fighting hordes of poxwalkers, and the occasional squad of fallen marines.

After two hours of marching. We had finally reached the Imperial lines, and I decided to do something exceptionally risky. The Death Guard had set up medusa guns firing blighted rounds, these would collapse the Imperial line in a day. To counter this Guardsmen sent raiding parties to destroy the guns, these teams would be supported by a detachment of Astartes, these marines will return to friendly lines once the raid is concluded due to the limited amount of Guardsmen supporting them, but it won't be an airborne extraction due to the AA weapons. With luck a Guardsmen sentry will believe they're just fighting the Death Guard, and believe the heraldry of the XV legion to be one of theirs.

I decided to risk it. I approached the lines and I thankfully heard a mortal yell "Hold your fire they're on our side!" I'm uncertain whether to thank, or despise the mortal's ignorance.

"My lord." I looked to see a squad of mortal guardsmen all bowing down to me, if a commissar or officer knew what we are, would they fire at me or the guardsmen first? "I was unaware that the raid would end so soon, did we succeed my lord?"

I was uncertain what to do, but I had to ensure they truly believed we are on their side. "I'm uncertain if we've successfully destroyed the guns, our drop pod was shot off course, so we returned to our lines before the Death Guard could overrun our squad." I had hoped that these guardsmen had never served with Astartes directly before, because both of these lies aren't characteristic of the Adeptus Astartes.

"I see my lord." The young what seemed to be a sergeant replied. Fear began to build within his mind, and it soon spread among his comrades like the blight that infests this world. No doubt due to our appearance, we're not the most subtle of legions

"I am a Liberian from the Draco Eques chapter, these are my bodyguards, and they've sworn an oath of silence." I could feel their fear dropping from my lie, at least he's familiar with the inconsistences among chapters. "Could I ask you a favor guardsmen?"

"Yes my lord?" the guardsmen now somewhat fearful of what I had to ask.

"Don't tell the other chapters of our failure, it would bring great to shame my chapter." And no doubt end in your death, but yet again if anyone found out about our encounter, you would be dead no matter what.

"Yes my lord!"

"You have my thanks. Do you know of anywhere remote that my chapter can establish a FOB?"

"I believe the lieutenant might have a better idea my lord." I guardsmen responded somewhat helpfully.

"I hope that your lieutenant is as helpful as you are guardsmen, the Emperor Protects." I was somewhat truthful in that statement, the sergeant ignorance means we may leave this world without pointless bloodshed, but it still and always saddened me that the Emperor is worshiped as a god. It's not what he wanted, it's more in line with Lorgar's line of thought.

"Thank you my lord, the lieutenant is in the observation bunker." The guardsman said while showing the sign of the Aquila.

Luckily it was easy to find the lieutenant, he would no doubt be less oath bound than the sergeant so I merely reached into his mind and grabbed the information I needed, completely melting his mind if I were not a son of Magnus I might have needed to physically make contact with him, but such actions as this physically drained me. I hope someone more competent takes over. Yet again the Guard is nothing compared to the Solar Auxilia, But this entire day is perhaps Tzeentch watching me amusingly. I merely shuddered at such a thought.

It was a simple two kilometer march to the northeast. Before we found an old warehouse complex. It is no doubt scheduled to become a barracks or an ammo depot, but it will serve my purpose well enough.

+Brothers, protect me for but a moment.+

The Rubricae moved into a defensive position, and I began the ritual. It would take hours of rites, and observations to ensure we would be safe in transit, and to find the correct current in the Ocean, but it's like trying to find a stream in a tidal wave. The biggest problem however was that I could hear howling. How did these bastards know so soon? "Don't you know that there are no wolves on Fenris."

"Silence warlock!" The booming voice behind the helmet, themed like a snarling wolf replied. "You will pay for your crimes against mankind!" All the while the preparing of boltguns on both sides was instantaneous.

"Wolf, I've heard that many times before. Before Horus betrayed the Emperor, during the sacrilege of Prospero." I began to laugh "When we burnt Fenris to the ground. And every time it's from a Wolf Priest, you know we're not so different, you and I."

"You're wrong we get our power from-"

"I swear it's the same response as well 'we get our power from the winds and spirts of Fenris!' You deny it wolf but your legion is nothing more than feral hypocrites!" I swiftly retorted, it's the same whenever I face a wolf, such predictable creatures. By the Ocean, the wolves that accompany them I respect more than their owners.

"Enough!" The Wolf Priest snarled.

"Indeed, I might give you a quick death." My Rubricae swiftly opened fire, killing five of the Wolves before the remaining ten closed the gap.

Ten on ten I thought, this will be a simple clean up. The drawing of Khopeshes was swift, no doubt the Vlka Fenryka were trained to face us in melee, however few sorcerers have a bond with their Rubricae like I do, many prefer to lead twenty, thirty, even hundreds into combat. But I prefer to lead my nine flawlessly, and my teaching as a Corvidae only boost their almost unnatural speed. The Wolves always fight with an equally unnatural speed, the only others this trained are the Black Templars, perhaps the Grey Knights as well. I watched the fight, my Rubricae can make decisions much more effortlessly in combat than most, using my abilities of precognition to predict where the Wolves will dodge. Such an ability is what saved many on Prospero, and what led many Wolves, including these ones to their deaths. Nothing is more amusing than seeing a Wolf dodge a blow, smile at its own speed, and be decapitated but mere moments later. The fight ended in mere moments, 4.79 seconds to be precise. I walked over the Wolf Priest who I ordered wounded, not killed.

"To Hel with you!" it yelled whilst coughing up blood. Its legs and an arm severed.

"Fly in the Great Ocean! And talk to the other Priests who said the same thing, if their souls survived." I merely stabbed him with my staffs' blade, only impaling one of its hearts, the wolf won't live, but it'll die slowly.

I continued my ritual. 'Soon' I thought to myself. Then I felt it, a void approaching, and fast, a sphere of nothingness. I felt such a presence before. The Silent Sisterhood! Why, why now? The sisters have not been spotted since Prospero! Why do they leave Terra now? Damn it all, if they got to close the ritual would be ruined. I have to do this now. I reached out to the Great Ocean, and dragged my Rubricae with me.

Terminus Systems

SSV Normandy SR2

Commander John Shepard, first Human Spectre, hero of the Citadel, a supposedly dead man, and now working with a xenophobic terrorist organization. On the plus side said organization is recruiting a few aliens. Mordin Solus, and Garrus Vakarian. Mordin's absolutely brilliant, and Garrus is an old friend, and the best shot he knows.

"Commander, the Illusive Man requests a meeting with you." A blue light stated.

"Alright I'll be down in a minute." Shepard replied. Thoughts on what it could be surged through his mind. 'Are the Collectors attacking?' 'Is it another recruitment op? If so who is it?' He has not slept since he was 'resurrected', he could only picture the possibilities of what the Collectors did to their captives. He headed to the lift, and activated the holographic node. It was a short walk to the briefing room, and nothing interrupts you when the crew has long since gone to sleep.

Arriving in the briefing room he noticed something off. "Miranda? The Illusive Man needs to see you too?"

"Apparently something big has come up, and he needs to see both of us." She stated.

The table lowered and the holographic 'stage' appeared, the two of them entered it.

"Glad you're both here." The Illusive Man blankly stated while drinking his brandy. "Something has come up that needs to be investigated, we're unsure if it's Reapers, or the Collectors, but something was transmitted on nearly every frequency on an uncolonized world." He activated his omni-tool and played the transmission.

"All is Dust" the Omni-tool blurted out, the tone was like that of an ominous whisper.

"The transmission ended as quickly as it began, this needs to be investigated ASAP."

"We'll check it out." Shepard responded to this new Intel.

"Best of luck Shepard" The Illusive Man stated before the transmission ended.

"Joker plot a course" Shepard ordered

"Aye Aye." Joker responded tiresomely no doubt his nap being interrupted.

"Any idea what this is about?" Shepard asked Miranda.

"No idea Commander. But if an unknown like this pops up and we need to investigate, it must be important." Miranda was being truthful in what she said.

"Alright, lets wake up the team. I need everyone ready in twenty minutes." Shepard ordered while walking to the armory.

I awoke from what felt like hours of rest, but it must have far shorter than that, the Ocean is a tricky thing especially with something as untested as this. I surveyed my surrounding, a green lush world ether most of the world is plains with a few hills, or it wins the award for largest natural field I've ever encountered. I then noticed his Rubricae, had formed a defensive circle around their master.

+Brothers do you hear me?+ I hoped for two things. Be it my fellow sorcerers to respond, or even better my Rubricae to once again be known as brothers.

But neither answered my call. Then I noticed the Raging Ocean, was but a Calm Pond. For once in millennia I felt truly alone.
