Re:Interdimensional Mercenary

(Sorry I took some while to finish it.)

After Adam had defeated Slaanesh. He returned to the Singularity, the broken Imperial Palace surrounded by the summoned Space Marines and Servants.

"Status report." Adam immediately asked Kaldor Draigo who approached him.

"The Daemon had been repelled and the breach of Immaterium had receded, Milord. However…" Kaldor Draigo didn't get to finish his words when everyone including Adam noticed the growing aura of wickedness and evil from the spot where the Sodom's Beast died.

There, the Holy Grail made its appearance. But it is undoubtedly still corrupted and overflowing with Black Mud. Then the mud suddenly moved as if alive and formed a humanoid shape and turned into the real Beast of Sodom.

"Please stay your blades. I do not come with the intention to fight." She spoke with her sickening sweet voice when the Grey Knights were about to attack.

The Beast of Sodom stared at Adam as their eyes silently communicated before Adam lift his left hand gesturing for everyone to stop as he approached the Beast of Sodom.

"Speak, what do you wish to talk about, Beast?" Adam said as he looked at the Beast of Sodom and knew this wasn't her real body. Instead, it's just a projection made of the Grail Mud. Attacking her would bore nothing but wasting effort.

"Hmn. Quite the hostility. But I simply wish to make peace knowing that you are strong and a bane of my existence." She answered with a nod as her smile never faltered. "My arrival here is nothing but an accident. I am simply not meant to exist in this timeline. Therefore, I wish to return to my proper timeline and wish for no further conflict. In exchange, I have crucial information that you are definitely interested in." She made a deliberate pause for Adam to guess but seeing the frown on his face. She decided to reveal part of it. "It's about Slaanesh."

Adam frowned deeper. He felt that the information was important. But allowing the Beast of Sodom to leave is also something he didn't want. After learning about the Beast of Sodom, allowing her to escape is like releasing a tiger back into the mountain. Who knows what she would be up to. But she definitely would harm humanity again. That is certain. However, to forcefully extract the information out of her is impossible. Unless he could find her true body.

Adam would like to reject the offer but to do that means he would risk another battle against this illusive opponent who is unlike Slaanesh, is quite smart to hide away her true body and only appear with a projection. Not to mention, the previous battles had taken a toll on his mind due to Slaanesh infiltration into his mindscape that he would rather not risk another battle.

In such a situation, he could only loosen his grip on his sword and sigh.

"Fine. But if you try to play any tricks…"

"I understand. I wouldn't dare." The Beast shook her head. Even if she is aware Adam is weakened mentally since she was there with Slaanesh the whole time. She is certain that Adam could kill her if he had no regard for his life, Servants and the success of the Singularity.

Although there is only a verbal agreement instead of a proper binding contract like Geis. The Beast of Sodom is satisfied with the deal because she can see that Adam really has no will to further the conflict and reveals the information.

"When you defeated Slaanesh. I definitely sense his existence is being extinguished. However, when he is at the brink of death. I could sense his soul was dragged away by an unknown power."

"Do what you will with that information and I hope we will not meet again, Adam Black." The Beast of Sodom said and gave him a last smile before the Grail Mud that made up her body suddenly lost its form and dispersed, revealing Nero lying unconscious in her birthday suit next to the Holy Grail which lost most of its power along with the corruption within it.

After the Beast of Sodom vanished, Adam was in the state of daze. He was pondering the information given by the Beast of Sodom and he felt an ominous chill that suddenly felt at his spine.

Meanwhile Jeanne quickly acts and covers the unconscious Nero with her cape that is part of her outfit she summoned. As for Artoria, she retrieved the Holy Grail and secured it. Jalter secure communication with Chaldea to inform them of the situation and completion of the Singularity.

When Romani inform that the Rayshift is ready to go. Adam looked hesitant as the Servants he summoned within the Singularity would not be able to Rayshift back to Chaldea and would be left behind.

"Your worry filled us with immense joy, Milord. To once again fight by your side is the greatest wish any of us could ask for. To ask for more would be ungrateful." Kaldor Draigo said, representing the Grey Knights who cheered immediately.

"Therefore, go without worry, Milord. If The Emperor willed so, we will meet again in the future." Kaldor Draigo wished not to be the reason to hold Adam back.

Seeing their wish, Adam couldn't be unreasonable and could only leave them behind. Once he leaves and they lose their summoning anchor, the Grey Knights would also be unsummoned.

"Actually, since the Chaldea already recorded their Saint Graph. It's become possible to summon them again in the future through the Fate Summoning System." Olga chips in while Romani becomes increasingly restless as the Singularity is breaking apart now that the Holy Grail has been retrieved.

Hearing what Olga had said relieved his worry. He turned around to address his Servants and said.

"Let's go."

Blue pillar of light swallowed each of them as Romani Rayshifted everyone back to Chaldea.

———

"Great work, everyone."

Olga, Da Vinci and Malcador were waiting at the Rayshift room for the returning group.

"Everyone must be exhausted after this mission. You all are dismissed and should take a rest. The debrief will wait until tomorrow morning." Olga informed the returning Servant and Adam but her eyes stopped at Adam as she had other words for him. "As for you, Adam. Unfortunately I would need you to report to the Medical Bay to be diagnosed under Malcador's advice." She added.

Adam did not refuse and nodded before he turned to Malcador standing next to Olga with Da Vinci. He could already guess the purpose why. It would be rather odd if Malcador didn't bother to check on him after Slaanesh managed to breach into his mind.

After Artoria handed the Holy Grail over to Da Vinci for safekeeping and her research. Everyone left the Rayshift room either back to their room like Sigismund or to stop by the cafeteria like Artoria who is famished after a strenuous battle.

In the Medical Bay or Romani's actual workplace half an hour later.

Most important figures of Chaldea such as Olga, Romani, Da Vinci and Romani gathered in the room with Malcador performing arcane rites to probe Adam's mind for any sign of tampering by Slaanesh or the Beast of Sodom.

Over a dozen rites were performed by Malcador until his brow was sweating and his face showed signs of tiredness. But his face showed an expression of relief as he finished the final rite.

"His mind is in perfect condition without any sign of tampering. At least that is what I could probe." Malcador said with a rare look of uncertainty.

Adam was forged and modified by the best minds of the Imperium, by The Emperor himself. Even Malcador has difficulty performing check ups when normally, he wouldn't even need to spare any effort to lay bare the mind of a Space Marine. This tells just how fortified Adam's mind was. But still able to be breached by Slaanesh.

Malcador feared that history might repeat like how The Emperor's traitorous sons were corrupted by the machinations of the Chaos Gods. But thankfully, he couldn't find anything left behind in Adam's mind.

"I could sense a 'but' in your words." Da Vinci with her sharp mind immediately pointed out Malcador's uncertainty.

Olga and Romani cock their brow at Da Vinci's words and look over to Malcador for an answer.

"Well, even if I am one of the greatest Psyker that ever existed in my time. I am still no match to The Emperor himself and he designed Adam's mind to be impregnable even by the influence of the Chaos. Or so it was." He shrugged his shoulders. "As such, not even I could with my best ability to properly diagnose his inner mind." He sighed in both defeat and amazement.

"I see…" Olga mutters as her eyes drift over to Adam who is still deeply asleep under the effect of a rite similar to anesthetic injection to put Adam into a state of relaxation which is impossible with the physique of a Primarch without specialized chemicals available only within the depth of most secure vault in the Imperium.

Concerns flash over Olga's eyes as she bit the edge of her lips. Her secret romantic feeling aside, Adam is the best Master available to her and Chaldea's disposal. With him spearheading the Singularities, restoring Human Order is only a matter of time. However, if Adam is compromised and all other Masters are still in cryostasis without hope of being healed yet. The Chaldean could only cruelly rely on the inexperienced Ritsuko to resolve the remaining Singularities.

Romani, who felt the atmosphere was a little depressing, tried to instill some optimism.

"I am certain Adam would be fine. He didn't look like the kind of man that would ever give in to his enemies." He said mainly to Olga but Malcador nodded firmly with a sense of pride in his subtle smile.

"Naturally. Adam would rather kill himself first than to succumb to Slaanesh's influence. Not because we raised him that way. But it's his vow and conviction for those who he fought to protect, those who fought alongside him, his allies that believed in him and those who had fallen to pave path for his victory." Malcador said in almost a whisper at the end as his face twisted into sadness.

After all, Adam's strongest drive to fight was his guilt. He didn't become the way he is from the very start. But through accumulated journeys and campaigns, his innocent early self was baptized by the bloody war waged across the galaxy, from the Great Crusade to the Heresy and Black Crusades. He slowly grows into a mold of a cold and emotionless leader to protect his fragile mind.

The atmosphere of the room suddenly becomes heavy. While what Malcador spoke sounded normal to himself. It wasn't for Olga and Romani. As for Da Vinci, it's debatable if she is even interested about Adam's survival except for his worth in research material and knowledge. As such, she remained unaffected by the heavy atmosphere and tried to change it.

"Since we are done here. Why don't I share Malcador and my recent findings about the potential usage for the Holy Grail we retrieved from the Orleans Singularity?" Da Vinci suggested.

———

Waking up in his own room. Adam had a huge scowl as he touched his face.

In his artificially induced sleep, Adam once again meets the god.

"A congratulation is in order for your victory against one of your lifelong enemies, the Chaos Gods."

"However, the victor must be rewarded. Wouldn't you agree too?"

"Wonderful."

"What greater reward for the hero who slayed the Demon Lord than a princess to reward for your effort?!"

"Oh, don't worry. I don't kidnap a random lass. She definitely gave her consent for this. She wouldn't be able to disobey you either. Not that she would, she is rather 'infatuated' by you after all."

"Well, you can summon her later as your companion. So, go and lose your V-Card or something. Being a ten millennia old virgin is hardly something to be proud of."

"Adios!"

Those were all the conversations Adam could remember. Rather than call it a conversation, it's more like a one sided dialogue since he can't even respond. However, his interests are definitely stirred.

Female companions from his past universe are rare. But one that is infatuated with him should only be Alina or did he miss someone? As for the 'unable to disobey' part does make him wonder why it is necessary.

Driven mostly by curiosity, Adam open the Companion tab on his System display while also trying to summon Alina and Sif. He laid his eyes on the details of his newest companion before his eyes and mouth widened with a cocktail of emotions running through his mind and face.

"What in the Emperor's name is this?" He mutters in sheer disbelief and exhaustion from what he had just seen.

"I must still be dreaming… it has to be…" Adam canceled his thought of summoning his companions before laying back down on the bed and closing his eyes.

"I'm too sober to deal with this. I need some Amasec…" He mutters but then remembered that his Primarch physique made it near impossible to get drunk without drowning in gallons of Amasec.

(AN: Idk how to include this. But in the Companion Tab, there is an icon that differentiates pets, mounts etc from human companions. The former for Sif and latter for Alina. Let's just say that Slaanesh is the former.)
