This night in the town of Gary Indiana, a man huddles over with his face between his hands in an ally. His surroundings are quiet with the exception of the occasional gunshot echos, heard from the outside. His garments are old jeans and a stained white shirt, which looked more like homeless rags than real clothing. A stench emanated from him due to the long period he had gone without having a decent shower.
A pop sound echoed from the darkness of the ally and the man lifted his head from between his hands slowly, looking in its direction. He could see a fading glow, outlining a book. The glow faded from the book and the atmosphere returned to normal. The man stared soullessly towards the book in the dark corner of the ally. He didn't move immediately but just stared into space for a while. His stare was filled empty and sad, like a man who had no hope anymore. Eventually, the man mustered up the last remains of his dwindling curiosity keeping him from completely disconnecting from the real world and becoming catatonic, to move and take a look at the book that had appeared.
He lifted the book in his hands and rubbed his thumb across the edge of the cover. It was a metallic color, dark green, and mysterious. There were markings and glyphs that had strange gears, machinery, and technologies that looked like magic. The cover constantly changed and morphed like a moving photo, turning into a handprint in the shape of a human hand on the cover. The man watched the book's changes quietly before smoothly placing his hand on the handprint.
Wrrrrrr** Hummm**
The book clanked and ground like a machine starting up. A dark green light filled the surroundings and the man dropped the book in fright. His eyes showed fear, breaking his apathetic state. No matter who you are, even if you want to escape from the world. Death will scare you. The man staggered back as the green light began to swallow the surroundings, including the man himself. The man didn't speak, but he opened his mouth in a silent scream. The man was mute, a man born without vocal cords. All he could do was widen his eyes as he disappeared from this world. The book shot into his right hand, highlighting his palm with a dark green shade, proving he is connected to it.
The man disappeared, but he finally understood what the book was and what was happening. The book transferred the knowledge into his mind the moment it merged into his right hand. This was a powerful multiverse artifact: the Corpum Mechanica. And he just became the trial taker. And now he was going to prove worthy of it. After this thought entered his mind, his consciousness faded into darkness, his existence disappearing from this world.
================================
Unknown Time, Taras Nabad
"We must move quickly. There are those who would seek to stop this." A hooded figure in red robes leads the way toward a large machine surrounded by heat and fire.
Standing behind him is a large marine in green armor. His right palm is completely dark green. He walks calmly through the surroundings as if everything is within his grasp. This was the man who was once homeless and placed his hand on the Corpum Mechanica. He had arrived in this universe as a marine almost a decade ago. He had been sent on mission after mission to kill the demons of hell, barely succeeding in his endeavor. And now, he had been captured by these aliens and this priest was leading him to what they call the divinity machine. Even after all this time spent in this cursed universe, he still doesn't understand how to progress in his trial. He has long forgotten about the Corpum Mechanica in his right palm. He has long given up the memories of his life on earth as a homeless.
Now, all that he focuses on is living past today. This universe he is in... is not a playground. Since the day he was brought here, he realized this world was familiar, but it also was a cursed universe. There is no hope here and the lights of the stars are slowly going out. The universe was dying and all these alien races keep trying to save it, justifying their slaughter of the human race and saving themselves by saying they will preserve the universe with their Ardent energy.
Of course, the man doesn't care about their reasons. In his mind, he only keeps his sanity by pouring his rage into the forces of hell. His thoughts are for what he can use to rip and tear next. He does not need to care about anything else. The Kahn must be stopped. The forces of hell cannot be used by them, they have been corrupted.
"... help you on your journey." the hooded figure finishes talking as the divinity machine glows in front of him with yellow and gold arcane symbols.
He steps into the strange coffin-like chamber and the pod door closes over him. The hooded figure turns on the machine and the golden light fills him up, connecting with the dark green palm print on his right hand. He feels himself becoming immortal (No life span limit, not unkillable), filled with super strength, speed, and agility. The green light of the Corpum Mechanica also arcs across his body, combining with the golden light of the divinity machine.
This day was the birth of the greatest Doom Slayer in the multiverse: The Doom Guardian.
================================
"... you fool. You have doomed all of creation. The light will go out. The universe is ending. You have destroyed everything! You are worse than the creatures of hell, more selfish than all of creation, you brought the end of everything with your hands." An unknown demon lurches forward as it dies.
The Doom Guardian leans over the dying hell abomincation without emotion, taking the final component of hell's greatest artifact into his hands.
"The last starlight has gone out," VEGA announces to the Doom Guardian in his robotic voice.
Buzzz*** Hummm**
The dark green light arcs out from Doom Guardian's palm, materializing the Corpum Mechanica book. Its light passed through the artifact of hell in his hand, absorbing it into the book. The light flickers and spreads, enveloping the Doom Guardian.
"Unknown energy detected, contact lost with Praedar Suit nexus," VEGA announces mechanically.
After 1 minute, Doom Guardian disappeared from his location. This Doom Slayer universe was doomed to die at the start, it was a dark parallel. It was a fallen universe, eroded by unnatural decay caused by a time loop of the Doom Slayer, but the original Doom Slayer died due to outside forces. This was the last time the cycle repeated, and the man became the new Doom Slayer to finish what needed to be done. This was a universe without its heroes, without its fated survival, a broken loop. A universe with a doomed fate, just like all 'dark parallel' universes. It was hopeless to expect any saving in a `dark parallel` with a time loop paradox like this one in the first place. All the Doom Guardian could do was hope that in the next one, there might be a chance to stop the total destruction.
