Xié Yīnyù (邪音玉): The Devil’s Voice in Heaven

The Celestial Spy Turned Traitor
Era: The Ascendant Purge (250,000 to 180,000 years ago)

The Celestial Realm has long held itself as the pinnacle of enlightenment and moral superiority, even if it occasionally behaves like a bureaucratic aunt clutching a clipboard and issuing sanctimonious warnings about “proper conduct.” Within that glittering hierarchy lived a woman whose legacy became both a cautionary tale and a prophecy. Her name was Xié Yīnyù, remembered as the Devil’s Voice in Heaven, reviled as a traitor, feared as a mastermind, and admired by a very quiet minority who mutter that perhaps the heavens needed a good shake.

This is her story. Or at least, the fragments that survived the Celestial attempt to scrub her from history. The heavens may rewrite archives, but stories have a habit of clinging to reality like stubborn moss.

The Woman Behind the Mask

Before she became a disgrace marked for erasure, Xié Yīnyù was a respected minister of the Celestial Court. She was one of those maddeningly competent officials who glided through government chambers like a swan through a duck pond. She possessed impeccable posture, a serene expression, and the unnerving ability to remember every tiny detail of an archive stretching across hundreds of thousands of years.

She was breathtaking as well. Celestial beauty tends to run to the “ethereal glow” end of the spectrum, but Yīnyù managed to look both celestial and dangerous, which was a novelty that few appreciated at the time. Her hair fell in a raven-black cascade reminiscent of ink pouring from a calligrapher’s brush. Her eyes shimmered like cut rubies. Her lips curved as though she always knew more than she ever intended to say.

Her wardrobe was strategic. White silk for daytime court appearances to maintain the illusion of purity that the Celestials loved to congratulate themselves on. Black silk at night. In the moonlight, she became harder to see and even harder to read. For Celestials, whose lives were built on the pursuit of order, ritual, and predictability, she was the beginning of a nightmare they had not yet recognised.

Most Celestials never questioned her loyalty. She did her job with precision. She spoke softly and smiled politely. Who would ever suspect the archivist who upheld records, history, processes, and protocols to be the one quietly setting the stage for the greatest internal catastrophe the Celestial Realm had ever seen?

Anyone with common sense, perhaps. But common sense is not a celestial specialty.

A Celestial Scholar with a Devil’s Heart

The origins of Yīnyù’s disillusionment lie buried under layers of sanitised reports. What remains suggests a mounting disdain for the Celestials’ rigid arrogance. The Celestial Realm prizes harmony as though it invented the concept. It sees itself as the keeper of cosmic balance. It views its own rule as inherently justified.

Yīnyù saw something different. She saw stagnation disguised as stability. She saw hypocrisy disguised as principle. She saw a civilisation that revered perfection yet punished independent thought. Whatever seeds of rebellion existed inside her found fertile ground in the quiet hours of solitary recordkeeping.

Enter the Devil Prince.

Records insist he was nameless. In truth, Celestials simply refused to write it down, possibly out of pettiness, possibly out of fear that speaking him into memory might summon him. He came from the Devil Realm, a place defined by subterfuge, cunning, and the rather admirable ability to discuss betrayal with the same tone one might use to discuss the weather.

He saw Yīnyù. Not the minister, not the archivist, not the ornamental gem of a well-kept court. He saw the fury she smothered under silk and serenity. He whispered promises of a realm that rewarded brilliance without demanding conformity. He tempted her with freedom and flattery and a vision that the Celestial Realm had never offered.

If the Celestials had bothered paying attention, they might have noticed the increasingly sharp glint in her ruby eyes. They might have noticed the shadows that clung to her robes. They might have noticed the way she withdrew from her colleagues and poured more and more time into the archives she alone controlled.

Instead, they slapped another merit on her file and congratulated themselves for raising such a model official.

The Birth of a Double Agent

Yīnyù’s role in the Celestial Court made her dangerous in a way no obvious warrior could ever be. She was a guardian of information. She had clearance to archives sealed behind layers of protection. She had authority to update records, adjust records, delete records, and create new ones.

Letting her near the system was like handing a matchbox to someone who had always wondered how quickly a palace might burn.

She began subtly. She altered incidental footnotes. She mislabelled a few low-threat Devil visitors. She allowed a summoned envoy entry without the standard cross-realm check. Then she began crafting false trails in earnest. She adjusted celestial intelligence logs to redirect suspicion toward minor officials who lacked the influence to defend themselves. Stirring up internal paranoia was easy. Celestials, after all, are remarkably good at pointing fingers once someone gives them permission.

Meanwhile, she smuggled Devil spies through celestial inspection points. She modified border surveillance reports. She ensured the Devils always remained one calculated step ahead.

And still, no one suspected her.

Not until the Night of Falling Stars.

The Night the Heavens Cracked

It began with a tremor. A subtle shiver through the Celestial Realm that most dismissed as atmospheric turbulence. Then the first star fell. A streak of light across the sky. Then another. Then another. Soon the heavens blazed with falling starlight, each streak a herald of calamity.

The attack that unfolded was not a battle. It was a slaughter. Devil assassins infiltrated the heart of the Celestial Court with terrifying ease. High ministers fell in clusters, their golden blood soaking into the jade floors. The Celestial generals, caught entirely unprepared, found their protective arrays collapsing around them as illusions clouded their senses.

At the centre of it all stood Xié Yīnyù, playing her flute.

Her instrument, Huàn Yǔ, meaning Whisper of Illusions, was an artefact of immeasurable danger. In her hands, it created illusions so vivid that the mind simply accepted them as truth. A single note from the flute could make an ally appear as an enemy. A phrase could alter battlefield perception. A melody could send legions marching into their own doom with smiles on their faces.

On that night, her music twisted the senses of the Celestial armies. Soldiers turned upon one another. Commanders attacked their own aides. Guardians abandoned their posts because the illusions had shown them a threat elsewhere.

The Celestial Realm teetered on the brink of collapse. Had the Devil Realm pushed harder, the heavens might have fallen entirely.

Instead, the unthinkable happened.

The Devil Prince abandoned her.

Whether he panicked, calculated her expendability, or simply wanted to save himself remains unknown. Regardless, he fled, leaving her exposed.

She had fought for him. Betrayed for him. Reshaped reality for him. And at the moment of his greatest need, he vanished like smoke.

The Celestials captured her soon after.

The Fall of Xié Yīnyù

Her arrest was public. Humiliating. The heavens paraded her through the capital in chains of heavenly jade. This was a woman once greeted with bows and reverence, now treated like a spectacle. Celestial crowds lined the streets. Some screamed. Some cried. Some trembled from fear alone.

Her face remained impassive.

When asked to confess, she refused. When pressed for motives, she remained silent. When confronted with her crimes, she said only one sentence:

“Your end will come from within.”

It was neither a threat nor a plea. It was a simple truth. A prophecy that struck fear through thousands.

Her execution came soon after. The heavens believed they could bury her legacy by burying her body.

History proved otherwise.

A Legacy Carved in Shadows

After her death, the Celestial Realm scrubbed her name from official records. They altered histories, sealed documents, and purged entire archives. Yet the Celestial Realm is enormous. Stories wander. Secrets linger. Rumours survive.

Today, Yīnyù remains a symbol of fear and rebellion in equal measure. Celestials cite her name when reminding junior officials not to “question the natural order.” The Devil Realm, naturally, views her as a tragic romantic, which is entirely on brand for Devils attempting to wash their hands of inconvenient truths.

Some ask whether she foresaw something the Celestials refused to acknowledge. Perhaps she glimpsed a flaw so deep that the only solution she could imagine was destruction. Perhaps her betrayal was not simply treason but an act of defiance against a realm that demanded perfection at the cost of authenticity.

Whatever her reasons, the Celestial Realm never recovered its former certainty. A quiet vulnerability lives beneath its polished exterior, a reminder that even the heavens can bleed.

Illustrative Scene

The Devil’s Whisper

The wind carried a faint trace of incense through the Celestial Archive. Spirit lanterns glowed softly, their light flickering over scrolls that held millennia of recorded truth. Xié Yīnyù moved silently between towering shelves, her black silk robes brushing against jade tiles. She reached for the scroll bound in gold thread, the one she had sworn never to touch.

A quiet laugh drifted from behind her.

She did not look up. She knew that laugh too well.

“You hesitate,” the Devil Prince murmured as he stepped closer. His crimson eyes gleamed with amusement. “You fear the choice you are about to make.”

“I do not fear,” Yīnyù answered. Her tone was steady, though her fingers trembled ever so slightly over the scroll.

He brushed a strand of hair from her cheek. The gesture was gentle. Possessive. Calculated. “Your hands disagree with you.”

She drew in a slow breath. “Once the seal breaks, the heavens will never forgive me.”

His smile deepened. “Then let them choke on their own sanctimony.”

She paused. The weight of her future rested in her palm.

“Would you go back, if given the chance?” he asked.

She lifted her gaze and met his.

“No.”

Her fingers tightened. The seal snapped.

A star fell outside the window.

And fate shifted.

Frequently Asked Questions

Why did Xié Yīnyù betray the Celestial Realm?

Her motives appear layered. She disliked celestial rigidity and hypocrisy. She genuinely believed the Celestial Realm had become stagnant and oppressive. Her relationship with the Devil Prince complicated matters further. Whether love or manipulation drove her is debated, but her ideological resentment was real.

Was she the mastermind behind the Night of Falling Stars?

Yes. She crafted the infiltration, altered the records that enabled it, and used her flute to manipulate the battlefield. Without her, the Devil Realm would never have breached the Celestial Court so deeply.

Was she evil?

Celestials say yes. Devils say no. Mortals shrug and say the heavens are dramatic. In truth, she occupies a morally grey space. She was brilliant, disillusioned, and ultimately betrayed by the very man she helped empower.

What happened to the Devil Prince?

He fled. There are whispers he met a miserable end. Others believe he remains active, manipulating events from the shadows. Devils enjoy good gossip, so the truth may never be known.

Did her prophecy come true?

“Your end will come from within.”
Many scholars argue this warning predicted later internecine conflicts in the Celestial Realm. Others suggest she glimpsed something deeper. Celestials hate this question because it implies she might have been right.

Why is her name still known if the Celestials erased her?

Secrets never stay buried in a multi-realm universe. Some texts survived the purge. Some demons preserved her story deliberately. Some celestial archivists hid records out of curiosity or guilt. History is stubborn like that.

Is Xié Yīnyù considered a villain or antihero in Mortal Redemption lore?

She is more an antihero. Dangerous. Rebellious. Flawed. Brilliant. Not noble but not senselessly cruel. She acted with intent, not carnage for carnage’s sake. Her legacy shapes celestial politics long after her death.
