Chapter 1: The Poisoned Oath
Moonlight cut through the high, narrow window of the armory’s hidden alcove, carving cold silver veins across the racks of polished steel. The air was still and thick with the ghosts of old iron and oiled leather, undercut by a faint, cloying sweetness. It was the scent of the night-blooming Jelara flowers from the ballroom, carried here on a sleeve or a breath, and it clung to everything. To the dust. To the forgotten ceremonial blades. To the remnants of a single shattered goblet lying in the corner, its wine long since dried to a purple stain.
Seo-hwan leaned against a worn practice dummy, his gloved fingers tracing a gouge in the wood. The porcelain of his mask felt cool, a permanent kiss against his skin. From here, the muffled music of the feast was a distant, pulsing thing, a world away.
The scrape of a boot on stone was his only warning.
A body slammed into him, all hard muscle and desperate force, pinning him against the cold wall. The breath rushed from his lungs. His head cracked back against stone, a bright spark of pain flaring behind his eyes.
“Mu-jin,” he gasped, the name more a wheeze.
The knight’s face was inches from his own, from the blank, smooth surface of the mask. Sir Kang Mu-jin’s broad shoulders blocked the moonlight, casting them both into deeper shadow. His eyes, usually so sharp and focused, were wide, the pupils dilated into black pools. His breath came in ragged, feverish huffs, washing hot over Seo-hwan’s cheek.
“Sir Kang,” Seo-hwan tried again, forcing his voice into a steadier register, the one he used for courtly functions. It sounded absurd here. “You’re not yourself. The wine. You must have tasted the wrong cup.”
Mu-jin didn’t seem to hear. One hand, still in its worn leather gauntlet, pressed into Seo-hwan’s shoulder, holding him fast. The other came up, trembling with a visible, terrifying effort. The fingers hovered a hair’s breadth from the lower edge of the porcelain mask.
“Remove it.” The voice was Mu-jin’s, but the growl in it was not.
“You are drugged,” Seo-hwan stated, his own heart hammering against his ribs. He didn’t struggle. To struggle would be to fight Mu-jin, and that was unthinkable. “The Knight’s Resolve. It was in the toast for General Kwon. It clouds the mind, twists duty into…”
“Remove it.” Mu-jin’s fingers spasmed closer. The sweet, cloying scent of the Jelara blossoms was strong on him. It mixed with the smell of his sweat, of his fear. “Let me see.”
“You have seen.” A cold stillness settled over Seo-hwan, a familiar dread. “You were there. You know what’s underneath.”
“I see a mask.” Mu-jin’s breath hitched. A tremor ran through the arm that pinned him. The drug was a war inside his veins, duty wrestling with a poison that whispered only of raw, unveiled truth. “I have given my life… every breath… to a piece of pottery.”
The words landed like physical blows. Seo-hwan swallowed, the sound loud in the intimate space between them. “You gave your oath to your prince. Not to his face.”
“They’re the same thing!” The shout was torn from Mu-jin, too loud, echoing off the blades around them. He flinched at the sound of his own voice, his grip tightening. He leaned in closer, his forehead nearly touching the brow of the mask. His next words were a raw, desperate whisper. “Or are they? Let me see what I’m truly protecting. Before I lose myself completely.”
Silence, thick and heavy, filled the alcove. The distant music swelled briefly, a jaunty, carefree tune.
Seo-hwan looked into the knight’s tormented eyes. This was the man who had stood watch over him for a decade. Who had eaten from the same plate to test for poison, who slept on a pallet outside his door, who had carried him, bleeding and broken, from the ashes of the old summer palace. This was Mu-jin, whose loyalty was the one unshakeable pillar in his life.
And he was breaking.
Seo-hwan’s gloved hand came up, slow and deliberate. He didn’t push Mu-jin away. Instead, he placed his hand over the knight’s trembling one, where it hovered near his cheek.
“You are not losing yourself,” Seo-hwan murmured, his voice low behind the mask. “You are right here.”
“I need to know,” Mu-jin insisted, but the fight was bleeding from him, replaced by a profound, drug-induced exhaustion. His weight sagged forward. “It’s all I can think. The poison… it screams it in my head. That I’m a fool. That I love a ghost.”
The word hung in the air. Love. It wasn’t meant like that. It couldn’t be. It was the loyalty of a sworn sword, twisted by the toxin. Yet it echoed in the stone chamber, undeniable.
Seo-hwan held his breath. He could shove him away now, call for the guards, have him restrained. It would be the safe thing. The prudent thing.
But Mu-jin had never asked. Not in ten years. He had accepted the mask as he had accepted his oath. And now, in this shattered moment, he was asking. Not as a knight, but as a man drowning.
Slowly, ever so slowly, Seo-hwan guided Mu-jin’s hand away from his face. He didn’t let go. He pulled the knight’s forehead down until it rested, with a quiet thud, against his own masked brow.
“You protect a man,” Seo-hwan whispered, the porcelain between them cool and absolute. “A man who trusts you with his life. With his back. Is that not enough?”
Mu-jin shuddered. A long, broken sigh escaped him. His other hand slipped from Seo-hwan’s shoulder, and he slumped, his weight fully supported by the prince against the wall. “It has to be,” he slurred, his eyes closing. “It’s all I have.”
The tension bled away, leaving only a deep, weary shame in its wake. Seo-hwan stood there, propping up the unconscious weight of his protector. The Knight’s Resolve did that—it burned through the system and left a corpse of exhaustion.
He looked over Mu-jin’s shoulder at the shattered goblet in the corner, the purple stain. A mistake. A servant’s error. Or something else.
Footsteps, light and careful, approached the alcove entrance. Seo-hwan didn’t turn. He knew the rhythm of that walk.
“He lives?” asked a soft, aged voice from the shadows. Lord Han, his spymaster.
“He lives,” Seo-hwan answered, his voice flat. “See him to his chambers. Quietly. Let it be known he overindulged in the general’s honor toast.”
“And the one who served the tainted cup?”
Seo-hwan finally shifted, maneuvering Mu-jin’s dead weight into a more secure hold. He looked at the peaceful, slack face of his knight, now free of its torment. “Find them,” he said, the words dropping like stones into the silent dark. “I would know who thinks to use my shadow against me.”
