The Heroine is My Stepsister, and I'm her Final Boss
Chapter 359 - 348: Aurora’s return
CHAPTER 359: CHAPTER 348: AURORA’S RETURN
The black-flamed torches hissed in the still air of the citadel. Their smoke curled like the breath of sleeping titans, heavy with brimstone and prophecy.
Atlas stood at the center of the great hall, surrounded by his fallen archangels. Their armor was battered and soot-stained, halos dimmed to mere rings of trembling light. The stone beneath their feet still pulsed with faint, residual mana — echoes of the faith that had once kept Hell itself trembling.
"Michael..." Uriel murmured again, her voice uncertain. "If the First truly walks again—"
"Then the heavens will stir," Raphael finished, his tone as sharp as the edge of his spear. "Their silence has lasted too long. Something’s coming."
Atlas’s gaze drifted toward the shattered windows of the hall. Beyond them, the red horizon trembled faintly, as though some unseen leviathan shifted beneath the skin of the world.
Before he could speak, a sound like cracking stone rolled through the chamber — slow, rhythmic, deliberate. The torches dimmed, bowing as a presence older than faith itself entered the room.
From the shadows beyond the gate, the Elder emerged.
He was cloaked in robes of ember-stained ash like usual, his eyes two pits of dim silver light. Time seemed to bend around him — the air thickened, the whispers of the dead grew silent. Even the angels felt the weight of him and lowered their heads in instinctive reverence.
"Guide....or should I call you Prophet," the Elder’s voice rasped, deep as the groan of mountains shifting. "You kneel on victory’s ash, and yet your hands tremble. You know what still waits below."
Atlas’s expression didn’t change. "...Asmodeus," he said flatly.
The Elder nodded once. "The final King of the Third. Keeper of the Gate to the Fourth Layer. The Warden of Desire." His voice carried a strange reverence, even fear. "He does not bow to faith, nor flame, nor crown. He bends only to purpose. And his purpose has not changed since the dawn of Hell."
The hall fell silent. Even the angels’ armor seemed to grow cold.
Gabriel’s wings shifted uneasily. "You’re saying he still guards the gate? After all this time?"
"He guards more than a gate," the Elder murmured. "He guards ’the will of Hell itself’. Slay him, and the Fourth opens — but with it comes the Reckoning."
Atlas’s gaze hardened. "Then so be it."
Uriel’s voice cut through the quiet. "Do you even know what lies in the Fourth? You’d drag all of us deeper into the pit on a whisper of prophecy?"
Atlas didn’t answer. He didn’t need to. His silence was its own conviction. As his conviction was the key. Not prophecy, not Guidance, only the key, only the Amrit.
But before the Elder could continue, the torches flickered violently — the flames bending away from the northern corridor as if recoiling from a greater light.
A new presence entered — steady, calm, unhurried — a whisper of motion against the tense heartbeat of the hall.
Aurora.
Her name rippled through the chamber like a forgotten prayer.
She moved through the fractured light with the gravity of something half divine, half broken. Each step echoed softly against the cracked obsidian floor, deliberate and weighted with the dust of war.
Her armor — once pristine white — was splintered now, its plates veined with molten gold, light leaking through the fractures like a dying star trying to remember how to shine. Her hair, once the color of sunlight, now burned silver-white, as if the brilliance had seared itself clean through her mortal hue.
She knelt slightly before Atlas, her head bowed. The motion was not subservience — it was ritual.
"Atlas...," she said, her voice a fragile thread woven from exhaustion and grace. "Forgive my intrusion."
All eyes turned toward her. Even the restless firelight seemed to draw back in recognition. She was supposed to be in the outer lands — beyond the ashen plains, leading the scouting host through the northern expanse of the third layer. No messenger had been sent, no word had arrived. And yet here she stood — whole, alive, luminous amid ruin.
The Elder, shrouded in his midnight cloak, tilted his head — his eyes gleaming faintly gold beneath the hood. When he spoke, his tone carried both reverence and suspicion.
"Child," he murmured, "how are you still whole?"
Aurora’s gaze lifted. Her eyes reflected the dim glow of the dying fires outside — twin mirrors catching the dance of fading embers.
"Because I met him," she said simply.
A pause, like a blade drawn across silence.
Uriel’s expression fractured. Her lips parted, a question forming, disbelief trembling behind her eyes.
"Who?"
Aurora’s answer came not as a cry, but as a whisper — yet it filled the room like the sound of thunder rolling over mountains.
"Asmodeus."
The word crashed into them.
Even the torches flickered.
For a heartbeat, the world itself seemed to flinch. The Fallen shifted, armor scraping against stone, wings rustling uneasily. Some whispered prayers, others curses.
Gabriel’s face hardened, his usual calm splintering.
"That’s impossible," he said sharply. "The King of Desire does not meet with anyone. He devours all who step within his dominion. Even demons fear to speak his name aloud."
Aurora did not answer at first. Instead, she reached for the clasp of her cloak. Her fingers trembled slightly — not from fear, but from something deeper, more unknowable. The fabric fell away in silence, pooling at her feet like liquid shadow.
Gasps echoed through the chamber.
Across her skin — her neck, her arms, even beneath the shattered plates of her breastplate — faint sigils glowed. They were not scars or brands. They pulsed with dim, rhythmic light, like veins carrying the blood of the cosmos. Each one was drawn in patterns too precise for mortal hands — geometry that bent perception if one stared too long.
"He didn’t devour me," Aurora said softly. "He spoke. He knew of you, Atlas."
Her voice trembled now, the calm cracking.
"He called you by name."
Atlas had been silent all this time, unmoving, but now his head tilted slightly — the faintest sign of disturbance. His eyes, twin voids ringed with gold, locked on her.
"...What did he say?"
Aurora hesitated. Around them, the others leaned forward, breathless. Even the flames seemed to still, their flicker arrested mid-motion.
When she spoke again, it was not a confession — it was prophecy.
"He said," she began, her voice dropping low, "that the Prophet
, the guide walks a darker path than any king of Hell ever dared. That when you reach his gate, Hell will already be damned."
The words fell like stones into a still lake, each one sinking deeper, leaving ripples that reached every soul in the hall.
No one spoke.
The silence that followed was not emptiness — it was a living thing. It pressed against their ribs, filled their lungs with cold.
Aurora lowered her gaze, her fingers tracing one of the glowing sigils across her wrist — the motion absent, almost reverent.
"He said he sees the end," she whispered. "Not of kingdoms. Not of gods. But of meaning itself. He said... when the Prophet stands before him, even the word faith will have no place left to hide."
Her words lingered — fragile and absolute.
Atlas stood motionless. The dim firelight played across his features, cutting his face into planes of shadow and gold. Inside him, something ancient and heavy stirred — not fear, not yet, but the echo of it.
For the briefest instant, he remembered the moment Dagon had smiled before erasure — that same quiet acceptance before the end.
He felt the weight of it settle on his shoulders again.
Outside, the black rivers of Hell shifted course, as if stirred by unseen winds. The banners of the fallen fluttered weakly against the dying heat. Somewhere far below, a distant bell tolled — though no one had built such a thing in this realm.
And still, Atlas said nothing.
Only the faint hum of divine energy around him betrayed his restraint. His jaw flexed once, then stillness again.
The others waited for his answer — for prophecy to reply to prophecy.
But all he said, finally, was quiet and terrible:
"Then let him wait."
Before anyone could answer, the heavy doors of the hall burst open with a crash that echoed like thunder. A Fallen soldier stumbled inside, his armor shattered, his wings mangled and half burned. He collapsed to one knee before them, gasping for breath, blood trailing down his face.
"My lord," he wheezed. "The northern watch—"
Uriel was already at his side. "What happened?"
The Fallen coughed, choking on soot and pain. "The northern army... they came... out of the fog." His voice trembled. "They weren’t demons. They weren’t angels. They were half-bloods—with eyes of gold and flesh of light."
Gabriel froze. "Demigods?"
The word struck the hall like a tolling bell.
Atlas stepped forward, his expression finally breaking into something fierce, cold, and knowing.
"So Heaven sends its children after all."
The Elder’s voice rumbled low. "The last barrier breaks, Prophet. The war of layers begins."
The torches flared white-hot, then guttered out — plunging the hall into a darkness lit only by the faint, trembling radiance of the Prophet’s eyes.
