As Siegfried was trapped at that moment, he then tried to adapt to his surroundings, he tried to observe what was around every corner, even though he knew that this was not even explained by logic. He then tried to create a general equation that he combined between Einstein's tensor and also a tensor that he created himself.
In several attempts, Siegfried failed because the two did not match at all, then Siegfried dismantled one by one the fundamentals in both equations. He found that one of the functions of Einstein's tensor could be combined with his, but by simplifying things again.
Gνμ, yes that's it, Siegfried reversed Einstein's equation, then he found a gap where this dimension is. He found something abnormal, it was right at the corner of each room, these rooms seemed to be created not from real matter, but from incompatible units of matter in Earth's understanding.
Siegfried was then suddenly pulled into the center of the room, his friend Retch was directly in front of him, with his head gripped by something disgusting, clawed, his teeth like extremely sharp fangs.
"Siegfried, you won't get out of here, ever, and ever." said a voice from above Retch's head.
Retch was screaming, he was panicking, but the entity was clawing and tearing slowly at Retch's body. This meant that the entity, Rothos, absolutely had the desire to mentally torture Siegfried deeply.
"This friend of yours, what a disgrace, more trash than a handicap." said Rothos, he then gradually increased the intensity with which he tore Retch apart.
Retch screamed even more, his blood was pouring out, Siegfried who saw it began to have mixed feelings, on the other hand, he had to maintain his principle of not killing, on the other hand, he still had an obligation to save his best friend, Siegfried was on the side of anger and sadness, he was starting to be a little naive, but he always managed to hold it all in.
Rothos then pierced Retch's eyes very sadistically, Siegfried who saw it cried out. "Retch!"
"Siegfried... my life, well, it won't be much longer than now, I hope we can meet again..." Retch said in a low tone, he was starting to bleed out.
"No! Retch, no matter what, you have to stay alive!"
Siegfried then tried to summon Nyarlathotep but to no avail. Rothos mocked him even more by torturing Retch even harder, Retch in a few moments later actually breathed his last breath from the world, he was already motionless, Siegfried then cried again, he no longer cared about controlling emotions, in the end he was an ordinary human.
Rothos then laughed even more at Siegfried. "Poor baby boy, you know, this friend of yours is so trashy, more trashy than anything, nothing more... nothing more than the most flawed thing!"
Siegfried then felt how he lived with Retch and created new things with Retch, he also remembered a letter from Retch which stated that: "If I am destined to be gone from this world, you Siegfried, you are my only friend who is closest to me. I consider you more than a friend, you are someone who is like a real brother to me."
Siegfried couldn't take it anymore, he tried to scream but to no avail, Rothos kept teasing him even louder, his voice ringing in Siegfried's head, Siegfried was getting more and more stressed at the situation, even he couldn't protect his own friend, the only friend he even had.
"You cripple! Idiot!" taunted Rothos, then he directed his attacks to the point that Siegfried was knocked back and his body had many wounds.
"You're too boring, Siegfried, you're a stupid bastard, you only rely on Nyarlathotep's power, right? What a fool."
"I'm not that guy, Rothos, not at all, I'm SIEGFRIED. DIDN'T YOU HEAR THAT? I AM SIEGFRIED." Siegfried shouted so loudly that his voice could have shattered several corners of the room.
"Baby is angry, huh? But you're still a Defect. NO MATTER HOW YOU TRY YOU'RE STILL A STUPID NAIVE CREATURE, CLINGING TOO TIGHTLY TO OTHERS." Rothos replied, his voice even louder.
Siegfried's previously injured body suddenly began to heal in an instant, who knows what power it was, but Siegfried could not stop it at all, the aura then enveloped very quickly into Siegfried's body, Siegfried's eyes turned green.
"I, am no longer human, Rothos."
Siegfried then immediately mutated quickly, his body really became strange, he mutated. Truly becoming a realized monster, his body then enlarged and naturally, Siegfried could control it like his own body.
"Rothos, I forever have no beginning or end. If you begin, then you are the end."
The current Siegfried named himself "Thanatos" which meant he was the bringer of death. However, he had to kill as a form of self-defense and as something that humanity should do. For there can be no salvation without killing.
Now, he strikes back and reflects all the attacks thrown at him, Rothos is not that easy to defeat, in fact, he is immortal. He has lived thousands of years without eating or drinking, even without sleeping, if he is injured his body will automatically regenerate intact.
After all that, Rothos fled back to Earth, Siegfried who had now given up his affiliation with Nyarlathotep completely followed suit. What Siegfried did not know was that the distance from that place to Earth was eight thousand light years away. Siegfried also did not fully recognize his new body, so he was quite pessimistic.
But to protect humanity, he then tried, he moved very fast towards the coordinates of Earth, the unexpected thing was that Siegfried was able to reach Earth with only thirty seconds of travel. Meanwhile, Rothos was still outside the solar system, far from Earth.
Surprisingly, on Earth, Retch was still alive, Siegfried who was now in a hurry also accidentally created an inscription on it right, it contained the warning he wanted to convey, he conveyed: "Evacuate immediately, because this arena will be destroyed."
Siegfried was well aware that he was only a shadow on Earth due to the dimensional difference, but it seemed that Retch could sense Siegfried's existence. Siegfried spontaneously flew up and hid Retch in a place that could not be detected by any detection device.
Rothos then arrived, after five minutes of traveling he crossed everything on the way. Rothos, who was basically an unpredictable villain, destroyed the town's residential area causing an explosion, killing at least ten people and severely injuring several hundred.
Siegfried who realized this immediately summoned a scythe that could and should take a life, regardless of physical condition. Siegfried then swung the scythe at Rothos, but failed, as Rothos was far more experienced in fighting. As a result, Siegfried's attack was completely meaningless. But still, Siegfried was Siegfried, there was no giving up for him.
"Rothos, you know? No matter how much you try, you will lose." Siegfried said in front of Rothos directly.
Siegfried then swung his scythe around like a red tornado, slowly, Rothos faded out of existence, leaving only a few parts of his body that turned out to be alive. When Siegfried really wanted to end it, Rothos' shadow then disappeared, his body was destroyed, but Siegfried really understood that Rothos would not just die.
Siegfried's body then returned to normal, his emotions completely stabilized, now he was much more relieved because no one could think that it was him, because he was basically invisible to Earth people. Siegfried then quickly stabbed Retch who he had hidden somewhere. After Retch was picked up, they went home.
On the way, Siegfried, who had become a three-dimensional entity as usual, was interviewed by Retch. "How did you survive that room?"
"A little push, you died there."
"Seriously? It's great that you can be provoked by that to bring out such terrifying power."
"Yeah, something like that." said Siegfried casually.
"By the way, what about Nyarlathotep?"
"He's gone, Retch. He was unable to unleash his power in that dimension." replied Siegfried spontaneously.
Then they got home, as usual, Siegfried was very diligent in making hot coffee with a little sugar before he finally took a shower. His favorite show started in a few minutes, Siegfried then took the time to watch the show.
After an hour of watching, Siegfried then went to take a shower to clean himself from unnecessary dirt. The clock also showed 22:00, meaning that he had been in the empty Rothos dimension for quite a while, at least he was almost crazy there, but still he was able to end everything quite quickly.
On the other hand, a solitary young man was then possessed by something abnormal, his nature spontaneously changed one hundred and eighty degrees from his previous nature. He secretly picked up a rifle quickly and neatly once at an illegal arms dealership without being noticed.
