Prologue: Arrival of Destruction
"The birth of the universe is a mistake. If civilization is a cancer emerging quietly from the boundless stars, then war is the only common language known to all intelligent life. To correct this mistake and to clean up this tainted universe, I have become the avatar of entropy and ascended to godhood while denying all gods. Destruction is not a process, but the outcome. On the path I promised, all Paths and Aeons will terminate in the heat death of the universe."
…
"I wonder, were those the thoughts going through whichever entity threw me into this body?"
Somewhere in an unknown galaxy, a human-looking man asked.
"Human-looking" was the best description for him, for his humanity existed only in appearance, and even that was a stretch.
After all, what human could survive in the void of space without a suit? What human could survive with a gaping wound in their chest? What human bled golden blood? What human's arm could separate from their body, unraveling entirely?
The answer was simple: no human.
That begged the question: what was he, then?
The answer could be distilled into one word: Aeon.
A mortal mind could barely grasp the concept of an Aeon, at best defining them as "mysterious beings of the stellar seas, embodiments of condensed philosophical concepts."
But that definition, poetic though it might sound, fell short. It was like trying to depict a star's collapse with a child's drawing: technically correct in shape, utterly wrong in weight.
For an Aeon was not merely a concept given form.
An Aeon was the consequence of a concept taken to its absolute extreme by a mortal.
A mortal mind can hold a concept.
A mortal heart can dedicate itself to something.
A mortal will can push beyond its limits.
But an Aeon is what occurs when a mortal takes that concept too far—so far that their humanity or identity collapses, and the concept consumes them.
The key to Aeonhood lies in one word: experience.
As for who—or what—this Aeon was, his idle musings left little doubt. The talk of entropy, of the end of all paths, of the heat death of stars and civilizations… it all pointed to a single entity:
Aeon of Destruction—
…
"Nanook." The white-haired man uttered his new name, arms crossed as he floated upside down in the endless expanse of space.
This Aeon had risen to power as a consequence of The Swarm, remnants of Propagation, and the Mechanical Empire. He had only watched as his homeworld was annihilated before his eyes. In that moment, he realized the truth—
The creation of the universe was a mistake, and thus he rose as the avatar of entropy.
Destruction, one of four Paths that would push the universe toward the end of Finality.
"Hah~ Even in another universe, Nanook can't escape being a villain capable of destroying the universe." Nanook—or rather, the Transmigrator who had become Nanook—sighed, shaking his head in exasperation.
Unlike the original Ruin Author, he had not been disillusioned by the universe, nor sought to destroy it. He had been an average joe, living an average life, writing average fanfics.
What reason could I have to destroy the universe? Nanook fell silent, pondering.
…
The answer came moments later.
"Boku no Pico."
Revulsion welled up in the gold-eyed man, and a distant star—millions of light-years away—that he had been observing brightened for a moment, then exploded, collapsing into a black hole.
"Ah, oops?" Nanook did not panic, calmly raising his hand toward the distant black hole. The concept of distance was obliterated in an instant, and the city-sized black hole appeared in his palm, no larger than a basketball.
Despite achieving such a godlike feat, Nanook remained level-headed. The information imprinted on his mind upon transmigration kept him grounded.
World: Lord of Mysteries.
A universe teeming with unspeakable horrors, whose very names could render even divine beings pregnant, regardless of gender.
"I was wrong," Nanook said, loosening his grip on the black hole. "A universe where men can get pregnant really is a mistake."
He finally understood why he had been sent here, especially as the Ruin Author.
The underlying principles of this universe leaned toward chaos and madness. This was not merely him echoing Klein Moretti's words, but a perception unique to an Aeon.
His gaze extended beyond the Physical World he occupied, shifting to the other two planes overlapping reality: the Astral World and the Spirit World.
Innumerable concepts—Darkness, Death, Omniscience, Change, and more—assaulted his senses instantly.
The concept that drew his attention most, however, was Lord of the Astral World and Dominator of the Spirit World. Both radiated a sense of… majesty. That was the closest mortal approximation of what he perceived. More importantly, he could see the "fingerprints" on these two concepts.
Both concepts bore multiple individuals' fingerprints, yet the first mark on each was deeply entrenched, while the later ones were faint, insufficient to create what humans would call evidence contamination.
"So Klein has already transmigrated," Nanook muttered, shifting his gaze back to the starry expanse while spinning the black hole on his finger. "Earth…"
From what he could sense, he was not in the Milky Way. Had he been, the Great Old Ones would have noticed the moment he transmigrated.
If he was being honest, he preferred it that way. Before engaging the fray, he needed to create a few Emanators, perhaps recreate the Antimatter Legion, and then sweep across the universe as a tide of Destruction.
"I wonder… can the Astral Barrier truly stop me?" Shrinking the black hole to marble size before swallowing it, Nanook thoughtfully stroked his chin as he reflected inward.

And for those who are familiar with star rail, yes, I made the titles of Nanook his Symbolism, cause that's how it is for Outer Deities/GOO's.
