Chapter Text
The Dokkaebi’s forehead was pressed so hard against the obsidian dais that blood had begun to well beneath his skull, dark and glistening under the purple light of the flames. He didn’t dare lift his head. None of them ever did, not when the air itself had gone thick and wrong, as if the whole assembly was holding its breath alongside him.
“Master.” the Dokkaebi rasped, its voice raw from groveling. “I only came to serve you. I only came to be useful.”
Gwi-ma didn’t answer right away. He rarely did when the lesser creatures came crawling to him like this. Silence was a weapon he wielded better than any form of punishment, and he let it stretch now, savoring how it made the Dokkaebi’s claws scrape nervously against the floor as he waited.
The demon king held no body, his essence and strength contained instead in the roiling purple flame that towered over the dais. Its edges were flickering, showing nothing more than lazy disinterest. When he finally spoke, his words came out low and edged with menace.
“Useful.” he repeated, tasting the word like something sour. “That’s an interesting choice for a creature that’s wasting my time with groveling instead of information.” A few motes rose from the tips of his flame and swirled impatiently while he considered the trembling form before him. “You said you had a secret worth my time. So far, all you’ve given me is the sound of your own voice.”
“I… yes, Master, of course, forgive me…”
“Don’t apologize.” Gwi-ma’s flame shifted, sending a wave of searing heat outward. “Apologizing wastes more time. Just tell me.”
Around the open dais, in the deep shadows beyond the reach of the purple light, other demons watched without watching, the particular skill of creatures who had survived long enough in the Underworld to know that curiosity, here, could be fatal.
“There is…” the Dokkaebi began, then stopped himself, some last flicker of self preservation warring with the certainty that he had already gone too far to turn back now. “There is a child, Master. A living child born of Saja parents. I’ve seen him with my own eyes.”
The roiling fire drew inward, contracting and brightening, and the heat pouring off it intensified until it felt less like warmth and more like forged iron held too close to the skin.
“Say that again.” Gwi-ma spoke softly. But softness from Gwi-ma was infinitely worse than shouting.
“A child.” The Dokkaebi repeated, his voice cracking. “Born of forbidden love between two Sajas. I… Master, I thought you would want to know. I thought it would please you. I thought…”
“You thought.” The flame surged, a tendril of fire lashing out and coiling around the Dokkaebi’s throat without ever quite touching flesh, but close enough that the creature’s skin began to blister from the proximity alone. “Do you know what displeases me more than betrayal?”
The lesser demon said nothing. There was no answer that would save him.
“Not being told everything.” The tendril tightened, and the Dokaebi’s whimper turned into a strangled sound. “Whose child.”
“I don’t… I don’t know. I only saw the face of the child. I swear it on my own soul I don’t know which of them…”
The coil of fire pressed closer, and a thin line of smoke began rising from where it hovered around the Dokkaebi’s throat. “Then you’re not as useful as you promised me, are you.”
“Please Master, I’ll find out, I’ll bring you a name, just give me time, I only wanted to serve…”
“You had your chance to serve me when you first learned of this. Instead you kept it. Weighted it. Decided how best to spend it for your own gain before you even thought to bring it to me.” Gwi-ma’s voice dropped lower, and something in it cracked open, ancient and raw beneath the fury, something that sounded almost like grief wearing the mask of wrath. “Do you understand what a child like that means? Do you understand what it costs me, to have something of mine slip through unaccounted, hidden, growing somewhere without my knowledge?”
The Dokkaebi just whimpered, resigned to his fate now.
“Everything in this realm belongs to me.” Gwi-ma continued, and now he was speaking less to the creature before him and more to the assembly of demons beneath the dais. “Every soul that crosses into my realm. Every drop of power my Sajas collect in my name. Every one of you… I allow you all to live, and in return, some of you thought they could hide things from me.”
The flame flared, blinding white at its core for one terrible instant.
“Trying to hide what’s mine.” Gwi-ma spoke quietly, more to himself. “We’ll see about that.” The Dokkaebi began to scream before the fire even reached him. The tendril wasn’t made of ordinary flame. It didn't flicker or dance, but threaded itself through the Dokkaebi’s veins like it was searching for something, burning him from the inside with a cruelty designed to inflict the most pain before the body gave out.
It didn’t take long until the screams stopped. When the fire finally receded, drawing back into the great column at the dais’s center, there was nothing left on the stone but ash and the faint smell of scorched bone.
Gwi-ma let the ash settle before he began the search. He reached outward, pouring his magic into the black rock of the Underworld and threading it down into the deep places, the old tunnels, the forgotten cellars where things liked to believe they could hide simply because no one had thought to look. Then further, through thin, worn places where the realms pressed close together, out into the mortal world itself, searching.
It shouldn’t have needed to come to this.
The bitterness was sharper than anything he let show outwards. His demons knew the rule. Every one of them knew it, had always known it, from the first day they knelt before him and traded whatever pathetic lives they had before for a place in his service. No children. No exceptions. There was no room in the Underworld for anything so soft. Love had no place here.
It had been an age since this had happened last. Long enough that he had allowed himself to believe, foolishly, that the lesson had finally taken, that the example he had made out of the last fools that thought they could still carry a mortal heart tucked somewhere deep inside was enough. Apparently it hadn’t been. Apparently there was always another fool who believed otherwise.
The search was costly, his power pouring out of him faster than he could easily replace it. Across the Underworld, the ground began to split and glow, thin veins of fire crawling out from beneath the dais in every direction, cranching and forking like something alive, seeking.
Water demons scattered from where the veins surfaced, hissing when the heat came too close. Faceless one froze in the open, the blank smoothness where their features should have been somehow conveying dread all the same, and didn’t move again until the fire passed them by. No one spoke. No one dared ask what was happening. They only pressed themselves deeper into the shadows and waited for the fire to pass.
Gwi-ma barely registered any of it. He was spread too thin to space attention for the terror of his own subjects. Every part of him was focused on. the task, threading through stone and shadow and the thin layer between worlds, searching, searching, reaching into the mortal realm now, brushing past mortal lives too quickly for any of them to ever know they had been touched at all, hunting for the child, for a flicker of what didn’t belong to the living.
There. Threads of him caught on something faint, hidden beneath layers of ordinary mortal life, but unmistakable once he knew to look for it. Not one thread, but four.
Something in him went very still, even as the rest of him kept unravelling outwards to be certain, to be thorough, to leave no possibility that he was missing a fifth, a sixth, some deeper rot he hadn’t yet found the edges of. Four children.
The search ended exactly when he willed it to and not a moment before, the vast reach of him drawing back inward all at once, the glowing veins turning black behind it until the last of the light folded itself back into the roiling fire at the dais’s heart. What remained there afterwards burned lower than it had in centuries, thin and unsteady, flickering at the edges like a candle does when it’s little more than a pool of wax. The effort had cost him more than he liked to admit even to himself. It would take time to rebuild what this search had taken.
But no matter. That was what the rest of them were for. His other Sajas would just need to work harder, deliver him more, feed him faster, until he was made whole again. They would not complain. They knew better than that. Some of the Sajs were the reason he had needed to spend this power at all. That debt too would be collected. In time. In full.
“Bring them.” he said, turning his words towards the Dokkaebi brave enough to still be standing around the edges of the dais. “All four. And their parents.”
“Yes, Master. ” a chorus answered him immediately.
“And spread the word.” His voice had gone quiet again. “I want every soul in this realm to witness, so they will be reminded of what happens to things that try to hide from me.”
~~**~~
The dais sat at the heart of the Underworld, a wide platform of black rock open to the bruised sky and surrounded by the horde of demons that had answered Gwi-ma’s summons. There was no roof over it, no walls. Nothing in the Underworld required shelter from a sky that never rained, that only ever hung low and red at the edges like it was still smoldering.
The great purple flame burned at the dais’s center as it always did, its light casting everything below in a sickly, restless glow. In front of it, chained at the wrists to iron rings sunk deep into the stone, knelt seven prisoners. Three sets of parents and one mother alone, her jaw set, refusing even now to look anywhere but straight ahead.
They didn't look like demons anymore. Whatever had marked them as such had been stripped from them when the Dokkaebi guards had dragged them onto the dais. What knelt there now looked achingly ordinary. Humans. People who might have been anyone’s neighbors, anyone’s parents, anyone at all, kneeling small and powerless beneath a sky that has never seen mercy.
At the edge of the dais, held fast in the grip of Dokkaebi guards, were four children. They were young, young enough that none of them understood what was happening or why, or what any of this had to do with them. They didn’t know what a demon was. They didn’t know this place had a name, or that the flame at the center of it was anything other than the single most terrifying thing they had ever seen in their short lives. All they knew was that they had gone to sleep in their own beds, in their own world, and woken somewhere else entirely, surrounded by monsters, watching their parents chained on the ground in front of something made of fire.
Su-bin strained against her restraints, reaching towards a boy with dark pink hair and eyes that hadn't stopped darting around since he had been dragged into this nightmare. “Abby.” she called, and her voice cracked. “Abby, listen to me.”
The boy, tall for the age of ten and already carrying himself with defiance too old for his face, twisted hard against the Dokkaebi holding him, and the creature had to dig his claws into him until the grip surely bruised.
“Let go of me.” Abby snarled, more animal than child at that. “Let me go, let her go, what’s this, what's happening? Let go!”
“Abby.” His mother’s voice, now sharper, brought his thrashing to a stop the way only a mother’s voice could. “Listen to me.”
Abby stopped, just for a moment and met her eyes.
“Whatever happens.” she said, low and urgent, each word costing her another piece of her soul. “You look away. Do you understand me? You don’t watch. You close your eyes and you don’t open them until it’s quiet again.”
“Mom, I don’t understand, What’s going on, why are we here?. What is that…” His voice broke and his eyes flicked towards the towering column of purple fire.
“Promise me you’ll look away.”
Abby couldn’t do it, couldn’t bring himself to speak the words, not with his whole body shaking in both fear and anger, not with none of this making any sense at all. But something in his face must have satisfied her anyway, some flicker of understanding even through the panic, because she nodded once like it was settled, and turned her gaze forward again.
Beside Abby, a smaller boy sobbed openly, his face streaked and swollen. He was straining towards a single kneeling figure, his mother. She hadn't spoken a word since she had been dragged up there. Her jaw was locked tight and her eyes fixed somewhere past the crowd, past all of it, as though she could will herself somewhere else entirely if she just refused hard enough to be present.
But as the final moments drew close, she finally spoke without turning her head. “Mystery. Stop crying.”
“Mom, please, tell them, just tell them whatever they want to know and they’ll stop, please, I don’t want..”
“I said stop crying.” Her voice didn’t rise. “You don’t beg. Not ever.”
Above them, Gwi-ma surveyed the scene, and though it had no face, no eyes, nothing that should have been able to convey expression at all, something in the shift of his flames made it plain that he was watching, weighing, savoring. It let the silence stretch, like he always did, giving the whole gathering a chance to sit inside the dread a little longer, to really understand the weight of what was about to happen before it happened.
“You all know why you’re here.” Gwi-ma said finally, and his voice carried across the Underworld, a trick of demonic power that made every word land in every ear as though spoken directly to them alone. “So I won’t waste my time explaining it. You knew the rule before you broke it. Every one of you knew, and every one of you decided your own wants mattered more than your service.”
The flame pulsed, brightening, and the seven kneeling former demons flinched as one.
“A realm without rules is just chaos wearing a crown, and I have no interest in ruling chaos.” The words swept over the crowd, and every demon went rigid. “But let’s be honest with each other, since honesty is apparently in such short supply among you. This isn’t only about order.”
A tendril of fire drew closer to Mystery’s mother, hovering just above her. The blistering heat singed the tips of her long, lavender hair and made sweat bead on her forehead.
“This is about the fact you took something that belonged to me...” Gwi-ma said, the words now holding that dangerous softness. “... and you decided, all on your own, that I didn’t have the right to know about it. That I didn’t deserve the truth. You built a whole secret life, with a child in it, and never once thought I might have something to say about what’s mine growing up somewhere I couldn’t see it, couldn’t shape it, couldn’t claim it.” His voice sharpened, just at the edges. “Give me his name.”
Silence.
“The father’s name.” Gwi-ma said again, patient like a predator. “Give it to me, and I promise you, this goes easier. For you. Possibly even for the boy.”
The woman’s throat worked once, a visible swallow, and for a moment something flickered behind her eyes that might have been temptation, the instinctive pull towards any offer of mercy, however thin. Then it passed, and her jaw locked tighter than before.
“No.” she said.
Gwi-ma studied her for a long moment, his flame dimming and flaring as he thought. Then the tendril pulled back, and the edges of the flame shifted as Gwi-ma admired the particularly stubborn demon. “Loyalty.” he mused. “How touching. How useless.”
Again the silence stretched, and when he spoke again, his voice had shed all pretense of patience.
“I gave you purpose. I gave you power. In return, I asked for very little. Obedience. And this one rule, this unbending rule, that none of you can claim to have not understood.” The flame surged upward, and the violet light bent and rippled across the assembly, gathering itself into something enormous. “You decided that wasn’t enough for you. That you deserved more than what I gave. So now you’ll learn what that decision costs.”
The children began screaming before the fire even touched their parents. They didn’t understand what was about to happen, only that the terrible burning thing above the dais had grown huge and bright and hungry, and that it was reaching for the people they loved.
“Mom!” Abby was fighting again, wild and useless against the Dokkaebi’s grip, screaming the word over and over like it might undo what was about to happen. “Mom, Mom, MOM!”
Su-bin found his eyes one last time through the chaos, through the fire beginning to spill outward and down towards the ring of kneeling parents, and even as her own mouth opened in unwilling agony as the flame began to take her, she mouthed the same words she’d given him earlier. “Look away.”
He didn’t. He couldn’t. His eyes were locked open, and he watched.
Closeby, Baby, the smallest of the children, barely old enough to understand any of the words being said around him, only that something terrible was happening to the two people who had always kept him safe, had gone past screaming and into wailing. His whole body shook as he reached with both hands towards his mother and father, fingers grasping at empty air because the Dokkaebi holding him wouldn’t let him go to them.
“Mommy.” he sobbed over and over, the word losing its shape the more he repeated it. “Mommy. Mommy!”
Somewhere in the crowd, pressed among the silent, watching ranks of demons who had come because attendance was mandatory, a Saja stood very still.
Jinu had seen executions before. In the countless years of service to Gwi-ma, he had seen more death than most mortal minds could hold without shattering and had learned to build walls around himself until watching didn’t have to mean feeling. It was a survival skill. It was the only way he had made it this far without losing his sanity.
But the walls he had built weren’t strong enough for this.
Baby’s voice cracked on the words again, high and raw and utterly desperate, a sound that belonged to nothing but pure grief, and something in Jinu’s chest split open along a seam he had thought had healed shut centuries ago.
Suddenly, he was somewhere else, beneath a different sky, standing at the gateway to a palace that may no longer exist, hearing his little sister call his name in exactly that voice, that same unbearable pitch of a child reaching for someone who couldn’t or wouldn’t reach back.
Jinu hadn’t reached back to her. He had chosen his own well being over his family. But he had told himself that story so many times, in so many different ways, that he had almost worn the pain and shame enough to almost be able to bear it. He had left his little sister and mother to die, and it had broken something in him that had never really finished breaking, that had only become something cold over the centuries, something that let him keep walking, keep serving his Master.
He looked at Baby, reaching uselessly towards flames that were about to take the only two people in the world who loved him.
Not this time.
He didn’t fully understand yet where the words came from and what he meant by that, standing frozen in the crowd with his heart slamming against his ribs. He only knew, with an unshakable certainty, that he wasn't going to let four children be swallowed by the cruelty of the Underworld. Not while he drew breath.
The fire finished its work, leaving nothing behind but drifting ash and the hard, ringing silence that followed the screams. The children had all gone quiet by the end, not because the fear and horror had passed, but because it had gone past screaming, into something wordless and hollow.
Gwi-ma’s flame settled, its light dimming to something lazy and sated.
“There.” he said, embers drifting off him. “Let that settle the matter, for anyone still tempted to test me.” Almost as an afterthought, his attention slid towards the four small figures still held fast by the Dokaebbi, still trembling and staring at the empty spot where their parents had knelt moments ago. “Now. What to do with these.”
He said it lightly and the casualness of it was worse than any cruelty he had shown before.
“They are not yet truly demons.” he mused and let a tendril of fire drift above them in a slow circle, studying each small, tear streaked face with the detached interest of an appraiser. “Whatever they are will finish emerging on its own, given time. But someone will need to see them through it. Someone will need to teach them what they are, and quickly, before they’re old enough to be a liability instead of an asset.” The flame stilled, and Gwi-ma's voice rose, carrying out over the gathered crowd. “So. Who will take responsibility for turning four orphaned souls into something useful?”
Demons throughout the crowd shifted, some looking at each other, others at the children themselves, calculating how much trouble a thing was worth before deciding if it was worth it at all. A few exchanged glances that were less concerned and more ugly, and that made Jinu’s stomach twist. He could guess what some of them were thinking. Four newly orphaned children, still weak, still reeling. There were demons in the crowd who would see that as opportunity rather than tragedy.
His legs carried him forward before he had fully decided on the matter.
“I will.” His voice carried across the dais and every head turned towards him at once, Gwi-ma himself included, his flame brightening with something between surprise and interest.
“Jinu.” Gwi-ma said, drawing the name out like he was tasting it. “Volunteering. That’s not a word I associate with you.”
“They need someone.” Jinu kept his voice leveled. “I can teach them what they need to know.”
Gwi-ma’s attention settled on him fully, and Jinu made himself hold still.
“How noble.” Gwi-ma said finally, and there was nothing kind in the words. “Very well. I’ll grant your request.” The flame seemed to draw closer, and heat pressed against Jinu’s skin. “But let’s be clear about what you’re asking for, Jinu Saja, because I don’t think you’ve thought this through.”
“Master…”
“These children are mine.” Gwi-ma said, cutting him off. “They were mine from the moment they drew breath, and they remain mine now that their parents are ash. Nothing about that changes.” A tendril of fire curled lazily near Jinu’s jaw, never quite touching but close enough to singe. “What you’re volunteering for isn’t rescue. It’s responsibility. You will answer to me, personally, for their obedience. For their training. For every single choice they make from this moment until I decide otherwise. If they fail me, you will fail me. If they defy me, that failure sits on you as much as it sits on them.” The heat pressed closer. “This isn’t kindness I’m granting you, Jinu. Do you understand?”
Jinu understood. This was a leash, yet another way Gwi-ma would control him. But the way Baby’s voice cracked on the word “Mommy!” rang in his ears. Then he thought of his sister’s voice calling his name from a doorway he had never been able to walk back through.
“I understand.” he said.
“Good.” The tendril withdrew, already losing interest. “Then they’re yours. Try not to disappoint me. It would be such a waste to have to do this all again so soon.”
~~**~~
The walk to Jinu’s house took them through the lower streets of the ruined cliffside city, through narrow paths cut into black rock, lit by scattered lanterns that did little to push back the deepening dark.
Jinu kept the four children close, one hand resting on Mystery’s shoulder, though the boy hadn't reacted to the touch at all, hadn’t reacted to much of anything since they had left the dais, walking forward with the mechanical steps of someone whose mind had gone somewhere else for safekeeping. Beside him, Romance cried openly, tears sliding down his cheeks while his small hand gripped Jinu’s sleeve like it was the only solid thing left in the world.
Abby and Baby were proving themselves more difficult.
“We have to go back.” Abby said for the third time, twisting against Jinu’s grip on his arm with a desperation that hadn't dimmed at all since the dais. “Maybe it’s not too late, maybe they’re not really… Maybe it was some kind of trick, maybe…”
“Child.” Jinu kept his voice as steady as he could manage. “There’s nothing to go back for.”
“You don’t know that.” Abby’s voice cracked, high and furious and terrified at the same time. “You don’t know anything, you don’t know them, let me go, let go!”
“I’m not letting go of you in the middle of the Underworld.” Jinu said, firm but not unkind, tightening his grip enough to keep the boy from bolting. “I know this is the worst night of your life. I know that. But I need you to trust me for a little longer, just until we’re somewhere safe.”
“Nowhere’s safe.” Abby spat, and the fact that it was true made Jinu’s heart ache.
Meanwhile, Baby had gone quiet and clingy, one small fist wound tight into the fabric of Jinu’s coat while he glanced constantly over his shoulder. “Are we going to see them again?” he asked, small and hopeful, adding to the ache inside Jinu’s chest. “Later? When it’s not dark anymore?”
Jinu didn’t have an answer that wouldn’t be a lie or a cruelty, so he said nothing, and let his silence be its own kind of answer. Baby was young, but he seemed to understand, because his face crumpled and he pressed closer to Jinu’s side instead of asking again.
They had made it to the edge of what passed as the trading quarter when they came across the Dokkaebi.
There were three of them, prowling near the mouth of an alley with the loose ease of creatures who knew this stretch of street belonged to them. They straightened as the small group approached, and one of them grinned, showing too many teeth, then pushed off the wall and fell into step alongside them.
“Well, well.” The Dokaebi’s eyes raked over the four kids with hunger. “What’s this, Saja? These little morsels look like humans, wonder if they taste like humans too.”
“Move along.” Jinu said, not slowing.
“No need to be rude., Saja. I'm just… admiring.” He gestured lazily at the children with one clawed hand. “Fresh little morsels, aren’t they? Still smell like the Human Realm.” He leaned down slightly, sniffing near Romance, who shrank back and nearly stumbled. “Mmm. Bet they’re sweet.”
Baby made a small, frightened sound and pressed himself so tightly against Jinu’s side that Jinu had to adjust his stance just to keep them both upright.
The change in Jinu happened all at once. One moment he was walking, and the next he had turned, positioned himself between the children and the Dokkaebi, and the air around him had gone very still and very cold. His expression hadn't changed much, but that was the most unsettling part of it all.
“I said…” he repeated, quiet and level. “...move along.”
The Dokkaebi laughed, though it sounded a little too forced. “Or what, Saja? This is not your turf. You going to…”
Jinu didn’t so much as raise a hand, but the air around him shifted, becoming suffocating and pressing down on the whole alley. He was one of Gwi-ma's own, one of the Sajas who walked between realms and answered to no one but the Demon King himself. The lanterns nearest to him flickered, their flames bending sideways as if trying to lean away.
The Dokkaebi’s grin faltered. His two companions further back had gone very still, their predatory ease draining out of them.
“I’m only going to say this once.” Jinu said, his voice still not rising. “These children are under my protection. If you’d like to test whether that protection is worth anything, I’m happy to indulge you. But I promise you, you won’t enjoy the lesson.”
For a long moment nobody moved, then the Dokkaebi took a slow step back, hands raised. “No offense meant, Saja.” he said, his voice pitched higher than before. “Just talk. We were just talking.”
“Then go talk somewhere else.”
The three of them melted back into the alley, and the pressure in the air eased as quickly as it had come. Jinu let out a slow breath and turned back to the children.
All four of them were staring at him.
Abby was frozen in place while Baby was holding on to his arm. Mystery seemed to be present for the first time, watching Jinu with wide eyes. Romance had stopped crying, hiccupping softly as he looked up at the man who had just made three monsters back away without lifting a finger.
Nobody said anything as they resumed walking, but something had changed in the way the kids looked at Jinu. Whatever he was, he had teeth, and he had chosen to use them on the evil monsters. He was a good monster, then.
The rest of the walk went quietly. No more pulling, no more questions, no more attempts to break free. Baby’s small hand found its way back into Jinu’s coat before long, and Romance stayed close at his other side along with Mystery. Only Abby still held a hint of defiance, his jaw tight and eyes flicking towards every side street they passed, measuring, calculating. Jinu glanced down at him once, understood what was happening, but said nothing, letting Abby keep counting his odds in silence.
~~**~~
Jinu’s house sat at the far edge of a residential quarter, half swallowed by shadow, a weathered structure of dark wood that had seen better centuries. The door hung slightly crooked on its hinges, and a single window near the front showed no light at all.
He stopped in front of it, tapped the lock with one claw, and looked back at the four small, exhausted faces watching him.
“This is it. It’s not much. But it’s safe and you can keep warm inside.”
He pushed the door open and the children shuffled closer together, peering past him into the dark interior. There wasn’t much to see, just shadows and the shapes of unfamiliar furniture.
Mystery, who hadn't spoken a single word since the dais, finally broke his silence, his small voice barely above a whisper. “Are there monsters inside?”
Jinu looked down at him. “Not yet.” he said and stepped inside, and one by one the children followed him into the dark.
