Arlecchino x Columbina
The Lunar Eclipse of the Hearth
The heavy white overcoat lay discarded on the floor like a fallen cloud, a silent witness to the shattering of Arlecchino’s iron-clad composure. In the heart of the Zapolyarny Palace, where every breath was measured and every glance was a gamble, the Fourth of the Fatui Harbingers stood stripped of her professional veneer. Her hands, stained black to the mid-forearm by the curse of her lineage, were trembling—not from the biting Snezhnayan cold, but from a heat that threatened to consume her from the inside out.
Columbina stood before her, a vision of pale, unearthly beauty. The faint, pearly light emanating from her skin illuminated the dark corners of the room, turning the shadows into a soft, violet haze. She was small, delicate in a way that defied the terrifying power she held as a Moon Goddess, and as she looked up at Arlecchino, her eyes were wide and filled with a curiosity that was almost childlike in its intensity.
"You are burning, Peruere," Columbina whispered, her voice a dual-toned harmony that vibrated against Arlecchino’s skin. "I can feel the fire licking at the air between us. It wants to be let out."
Arlecchino reached out, her fingers tracing the curve of Columbina’s jaw. The touch was a collision of extremes—the searing, cursed heat of Khaenri'ah meeting the ancient, marble-cool authority of the Trilune Goddess. "If I let it out, Columbina, it might destroy everything in this room. Including you."
Columbina laughed, a sound like glass chimes in a storm. She stepped closer, closing the final inch of space until her bare chest pressed against Arlecchino’s silk shirt. "I have seen the sun die and the moons shatter, little flame. Do you truly think your fire can harm a creature that was born from the void?"
She reached down, her hands moving with a terrifyingly serene confidence to the waistband of Arlecchino’s trousers. The Fourth Harbinger’s breath hitched, a sharp, ragged sound that betrayed the war raging within her. For years, she had buried her desires beneath layers of duty and the heavy mantle of "Father." She was a protector, an executioner, a leader—she was not supposed to be a creature of the flesh.
But Columbina was not a person; she was an inevitability.
As the fabric of Arlecchino’s trousers fell away, the secret she had kept hidden even from her closest subordinates was revealed. Her body, tempered by a thousand battles and cursed by an ancient bloodline, bore the mark of a duality that few could fathom. Her lineage was one of creation and destruction, and that power manifested in a physical form that was as imposing as her reputation.
Columbina’s eyes dropped, her gaze fixing on the sight with a mixture of awe and genuine, wide-eyed concern. She reached out, her fingers hovering just inches away from the heavy, pulsing length that now stood between them, dark and marked with the same obsidian veins that stained Arlecchino’s hands.
"Oh," Columbina breathed, her voice losing its melodic chime for a moment of mortal shock. "Peruere... it is... very substantial. Are you sure? The space within me was crafted for moonlight and whispers, not for such a... formidable flame."
Arlecchino felt a rare flush of heat creep up her neck, her obsidian eyes darkening until the red 'X's seemed to glow with a predatory light. She leaned down, her voice a low, dangerous growl. "You were the one who spoke of gravity and stars, Columbina. You were the one who said the moon has no shadows to hide behind today. Are you afraid now?"
Columbina tilted her head, her hand finally making contact. Her touch was like ice on a fever, a sensation so sharp and cooling that Arlecchino nearly buckled at the knees. "Not afraid," the goddess murmured, her thumb tracing the crown of Arlecchino’s heat. "Just... wondering. It is like trying to fit the entirety of a volcano into a single, small cave. It seems mathematically impossible."
"Then let us redefine the mathematics," Arlecchino replied.
She swept Columbina up into her arms, the girl feeling weightless, as if the gravity of Teyvat had no hold on her. Arlecchino carried her to the bed, the charcoal silk sheets still carrying the scent of their shared morning. She laid the goddess down, the magenta highlights in Columbina’s hair spilling across the pillows like a sunset over the tundra.
Arlecchino moved over her, a dark shadow eclipsing the moon. She used her knees to nudge Columbina’s thighs apart, revealing the soft, damp heat that waited for her. The air in the room was thick with the scent of ozone and Glaze Lilies, a divine perfume that made Arlecchino’s head swim.
"You are so small," Arlecchino whispered, her hands pinning Columbina’s wrists to the bed.
"And you are so much," Columbina replied, her breath coming in short, rhythmic gasps. Her eyes were wide, the sparkling patterns within them spinning in a frantic, beautiful dance. "Please, Peruere. Show me. Show me the fire that keeps the House warm."
Arlecchino guided herself to the entrance of Columbina’s heat. The goddess let out a soft, sharp intake of breath as the first tip of the intrusion made contact. She was tight—impossibly so—her body resisting the sheer scale of what Arlecchino was offering.
"Wait," Columbina gasped, her back arching off the mattress. Her hands gripped Arlecchino’s forearms, her nails digging into the blackened skin. "It... it feels like I am being stretched by the horizon itself. I don't think... I don't think it will all fit."
Arlecchino paused, her muscles corded with the effort of restraint. She looked down at Columbina, seeing the genuine tremor in the girl’s lips. "I can stop," she offered, her voice strained. "I do not wish to break you, even if you are a god."
Columbina shook her head, her magenta-streaked hair whipping across the pillow. A few white feathers manifested in the air, dissolving against Arlecchino’s sweating skin. "No. Do not stop. I want to be full of you. I want the fire to reach the very back of my soul. Just... be slow. Even the moon takes time to move the tides."
Arlecchino nodded, her jaw set in a line of grim, focused determination. She began to push, a slow, agonizingly steady inching forward. She felt every ripple of Columbina’s resistance, the way the goddess’s body fought to accommodate the sheer mass of her. It was a battle of wills and anatomy, a slow-motion collision of two celestial forces.
Columbina’s eyes rolled back, a low, keening sound escaping her throat. It wasn't a sound of pain, but of a profound, overwhelming sensory overload. To a being that usually existed in a state of ethereal detachment, the physical reality of Arlecchino was a revelation.
"It’s... it’s so hot," Columbina whimpered, her legs curling around Arlecchino’s waist, pulling her deeper. "It feels like you are branding me from the inside."
"I am," Arlecchino growled, her control finally snapping as she felt the last of her length vanish into the goddess’s depths.
The fit was perfect, a pressurized, suffocatingly tight embrace that made Arlecchino’s vision go white at the edges. She stayed still for a moment, letting Columbina adjust to the fullness, watching as the girl’s chest heaved and her skin flushed a delicate, rosy pink.
"You did it," Columbina whispered, her voice a breathless wonder. "The volcano is in the cave. And it hasn't collapsed yet."
"Not yet," Arlecchino said, and then she began to move.
The rhythm was not the slow, graceful glide of a goddess; it was the relentless, driving force of a soldier. Arlecchino moved with a primal intensity, each thrust carrying the weight of her lineage and the frustration of her years of solitude. She was no longer "Father" or "The Knave." She was a force of nature, a wildfire burning through a field of snow.
Columbina met her with a surprising, frantic energy. She was no longer the serene, unbothered statue. She was a woman possessed, her hips rising to meet every strike, her voice rising in a series of melodic, wordless cries that filled the room. The air around them began to crackle with static, the Hydro-like essence of her power clashing with Arlecchino’s Pyro in a silent, invisible storm.
"More," Columbina pleaded, her eyes snapping open to fix on Arlecchino’s. The glowing highlights in her pupils were blinding now. "Give me all of it. Burn the shadows away, Peruere!"
Arlecchino didn't hold back. She drove into the goddess with everything she had, her hands moving to grip the headboard as she hammered against the divine heat. The bed creaked under the weight of their union, the silver ornaments on the nightstand rattling as the very foundations of the room seemed to tremble.
The fire in Arlecchino’s blood was no longer a curse. It was a fuel. It surged through her, focusing entirely on the point where she was joined with Columbina. She felt the goddess’s internal muscles clenching around her, a rhythmic, pulsing suction that threatened to draw the very life out of her.
"I’m... I’m going to—" Arlecchino started, her voice breaking.
"Yes!" Columbina screamed, her voice reaching a frequency that shattered a crystal vase across the room. "Fill me with the flame! Let the moon burn!"
Columbina’s body suddenly stiffened, her eyes glazing over as a wave of pure, lunar ecstasy washed over her. Her power erupted, a blinding flash of white light that filled the room, turning everything into a world of silver and shadow. At the same moment, Arlecchino let out a roar of triumph, her own release flooding into the goddess with the force of a breaking dam.
The heat was absolute. For a few seconds, there was no Arlecchino and no Columbina. There was only the white-hot center of a star, a place where fire and water were the same thing, where the past and the future were consumed in a single, eternal moment of connection.
As the light faded and the air began to settle, the room returned to the grey, cold reality of Snezhnaya. But the silence that followed was different. It was the silence of a battlefield after the final blow has been struck—a peaceful, exhausted quiet.
Arlecchino collapsed onto Columbina, her chest heaving, her skin slick with sweat. She felt drained, her cursed fire reduced to a low, comfortable ember that no longer clawed at her mind.
Columbina lay beneath her, her eyes half-closed, a dazed, blissful smile on her lips. A few stray white feathers were stuck to her damp skin, and her hair was a tangled mess of black and magenta. She looked utterly spent, a goddess brought down to earth by the simple, violent beauty of the flesh.
"Did it... fit?" Arlecchino asked, her voice a raspy whisper.
Columbina let out a soft, shaky laugh, her hand moving to stroke Arlecchino’s asymmetrical bangs. "It fit, Peruere. It fit so well that I think I have forgotten how to be a goddess. I think I am just... Columbina now."
Arlecchino shifted, pulling herself out of the girl’s warmth with a slow, lingering reluctance. She rolled onto her side, pulling the charcoal sheets over them both to shield them from the returning chill.
"The Jester is going to kill me," Arlecchino murmured, looking at the smashed vase and the discarded coat on the floor. "I have missed the briefing by two hours."
"Let him come," Columbina said, snuggling into Arlecchino’s side, her head resting on the Harbinger’s shoulder. "I will tell him that the Fourth was occupied with a matter of celestial importance. He wouldn't dare argue with the moon."
Arlecchino closed her eyes, feeling the steady, rhythmic purr beginning to vibrate in Columbina’s chest again. The fire was quiet. The shadows were still. And for the first time in her life, the Knave felt as though she had won a battle that actually mattered.
"You are a menace, Columbina Hyposelenia," Arlecchino whispered.
"And you are my sun," the goddess replied, drifting off into a deep, dreamless sleep.
In the hallway outside, the staff of the House of the Hearth had finally dispersed, the rumors of the morning replaced by a respectful, bewildered silence. They didn't know what had happened behind those heavy oak doors, and they would never truly understand. All they knew was that for a few hours, the cold heart of their Father had been warmed by a light that didn't belong to this world.
And as the sun finally began to set over the palace, casting long, purple shadows across the snow, the two Harbingers remained locked in each other's arms—a fire and a moon, finally at peace in the dark.
