The sanctum was built from paradox.
It lay beneath the skin of reality, woven between the folds of time where silence reigned eternal and memory refused to decay. The walls were not made of stone or spirit or soul—but of stillness, enforced so profoundly that even thought moved slower here. It was the prison of an idea, locked away so thoroughly that the world above had almost forgotten its name.
Rin stepped into the threshold of this impossible domain, his steps echoing like sins in a temple that had not heard prayer in an epoch. Shen followed behind, silent as his namesake, his mirrored eyes flickering with disquiet. Even he—eroded of emotion, hardened into a weapon of despair—hesitated here.
Before them lay the inner sanctum: a vast obsidian chamber ringed by concentric chains of celestial script. The ceiling arched endlessly, painted with constellations no longer recognized by any living sect. Each star was a sigil — a ward. Each flicker of their cold, blue light pulsed with the intent of a hundred forgotten gods who had once ruled this reality.
And in the center of the chamber, bound beneath a shrine of petrified prayers, knelt the god who had tried to kill death.
It did not look like a god, not anymore.
Its form was fluid, halfway between light and bone, with joints that fractured time when they moved. Thousands of threads impaled its flesh, each one a promise of punishment spoken by divine tongues lost to the ages. Its mouth had no lips. Its eyes had no irises. And yet it saw Rin—not with sight, but with memory.
"You have come," it whispered, voice blooming in the marrow of Rin's bones. "You, who carry the scent of graves not yet dug. You, who refine the endings."
Rin said nothing. He walked closer, feeling the Death Core in his chest pulse once—twice—as if aware it was in the presence of its conceptual antithesis.
This was not a being who defied death.
It was the idea of denying death. The god whose name had been struck from all tablets, who had tried—through cult, through doctrine, through twisted rituals—to sever death from existence itself. Its followers had called it Thassir, the Breath Unending. Others knew it only as The Withholder.
But none dared speak of it now, not in any living domain.
"You fear me," the being said, voice rich with old grief. "And yet, you pity me."
Rin's expression did not waver. "No. I understand you."
At that, the god stilled.
Rin continued, circling the shrine slowly, gaze taking in the metaphysical bindings that encased the god. Chains of petrified time. Shackles crafted from oaths sworn in the tongues of origin. A collar of endless return, which pulled the god back into existence each time it tried to dissipate.
The only reason this god still existed… was because it couldn't die.
"You tried to rip death from the cycle," Rin said at last. "To erase endings. Why?"
A low chuckle rolled across the chamber like a wave of cracked bones. "Because death… hurts."
The god's form flickered, momentarily becoming a radiant mother cradling a decayed infant, then a youth kneeling beside his slain love, then a thousand other echoes, grief without cease.
"I was born of mourning," it said. "From a world that screamed at the sky, begging for permanence. I heard their prayers. I answered."
Rin's eyes narrowed. "And you failed."
"No." Its voice sharpened, almost indignant. "I succeeded. For one sliver of time, I severed death. The cult that bore my will—The Immortal Choir—transcended the cycle. They lived. And lived. And lived. Until madness rotted their minds, until identity eroded into endless stasis. They could not die. They could not change. And so… the world moved on without them."
Shen spoke then, cold and analytical. "And the forgotten gods who bound you here?"
"They feared the infection of permanence," the god rasped. "They knew immortality was not a blessing, but a trap. So they wove the sanctum. They made me stay. Not as punishment—but as proof."
It paused, head tilting toward Rin. "And now you, child of refined death, have come. You wear pain like armor. You shape it into knives. Finish it. End me. Erase what should never have been born."
Rin studied the being. Not with hatred. Not with awe. But with the clinical gaze of one who saw the usefulness buried inside the rot.
"No," he said at last.
The god recoiled, its myriad forms shifting in confusion. "Why?"
"Because destruction is a luxury I cannot afford," Rin said. "What you are—what you represent—is not meaningless. It is a truth. An infected, shattered truth... but a truth nonetheless. That immortality must hurt to mean anything. That to be unkillable is to become hollow."
He stepped closer, drawing Ny'xuan—the sentient dagger forged from a death god's bone—from its sheath. The blade hissed in approval.
"I won't destroy you," Rin said. "But I will refine you."
He raised the dagger. The air thickened. Chains screamed as the act defied all expectations.
The god trembled. "You would take from me?"
"I will take only enough," Rin whispered.
Then he plunged the blade into the god's essence—not into its flesh, but into the concept of its immortality. The blade drank deep, pulling from the being not its power, but its contradiction.
A sliver of essence flowed into the dagger, and the weapon changed.
The bone darkened, etched with fractal runes that pulsed with paradox: death that devours eternal life. The blade now held a conceptual edge, one honed to sever the unseverable.
Ny'xuan pulsed, alive with new hunger.
And Rin... felt a shift within.
He had not killed the god.
He had made it useful.
The being sagged, its chains slackening as it slumped forward, hollowed but not gone. Its eyes—if they could be called that—looked at Rin not with anger, but with a strange gratitude.
"You carry my ending," it said softly. "And so... I live in a truer way than I ever did."
"Then stay," Rin said. "Watch. One day, I'll kill a world that thought itself eternal."
He turned away, sheathing the newly transformed dagger. Shen followed, silent, but his mirrored eyes were no longer empty. Within them shimmered a new kind of fear: that Rin could look at something as monstrous as an undying god and not reject it, but absorb it.
They exited the sanctum together, the doors closing not with sound, but with finality. Behind them, the god wept—not in sorrow, but in release.
Outside the sanctum, time moved again. Winds that hadn't blown in centuries stirred dust along the path of the broken temple. Shen looked to Rin.
"You refined immortality," he said. "Into a weapon."
"I refined the lie of it," Rin corrected. "What is immortal can be killed. You only need to understand what keeps it alive."
He looked down at his hand, where Ny'xuan now pulsed with impossible potential.
"To kill an idea," Rin murmured, "you don't just destroy it. You make it obsolete."
And so the dagger now bore the name of its essence: Vermis Eternum — the Worm of Eternity, a blade that devours unkillable truths.
For Rin had learned something crucial in that sanctum:
Hate was a waste.
Everything, no matter how monstrous, had its place. And his path—the Death Refinement Dao—would not waste anything. Not gods. Not grief. Not even immortality.
