The screwdriver was in my hand. The house was still on fire.
Miasma breathed off the roof in thin, dirty threads. They settled along the places my body liked to move, the way a cat settles on the one shirt you actually need to wear. The brass ribs of the tower framed a pale, fake sky that fooled nobody. The Archduke didn’t rush. He closed the space around me like a craftsman closing a box—one neat, perfect side at a time. A veil sagged across my favorite entry point. An after-blade of solid miasma settled a hand’s width behind my shoulder, as patient as gossip.
He spoke, his voice quiet as someone giving advice to a friend they were about to execute. "No breath shall steady."
The roof put a cold finger on my throat. Not choking. Just a stutter that lived in every exhale, like my lungs had been told a bad joke mid-sentence. He pressed through it with a clean three-piece attack: a feint to make my eyes go up, a true cut right where a late parry wants to live, and a sleeve-check to nudge my pelvis toward a veil that pretended to be innocent.
Valeria’s bone-shell cracked again with a sound like breaking ice. "Rude," she said in my palm. "Invoice later."
He rotated his wrist. The miasma thickened at my elbows and my ankles, just enough to tax the corrections that mattered. I flicked a mean little sound-spell at his timing hand and got nothing but honesty back. He ignored the noise and put his edge where it was supposed to be. I was losing. The ring was closing. The day was going to end where this roof pointed.
He lifted his chin a hair. The next vow gathered in the air like thunder under your shoes.
And then a window opened where no window lived.
It wasn’t a sound. It was a change in the way the room felt about warmth and honesty. A subtle pressure shifted. The light in the far corner of the roof went white and black at the same time—not mixed, but side-by-side, like two crowns that refused to argue. The lattice of my own nine-circle circuits found a beat they liked without asking my permission first.
"Hello, Arthur," Lucifer’s voice said from the rim of the roof, as easy as someone stepping into a warm kitchen.
I didn’t look away from the red coat and the blade. I didn’t need to see him to know what had just stepped through. The air went sane for half a breath. The miasma veils shivered, unhappy with the new temperature. The Archduke glanced a single degree toward the new arrival and then re-centered his focus on me, like a man who has found a mistake on an invoice but intends to sign it anyway.
There was a small, cheap flicker of a feeling inside me that I killed before it could learn to stretch. Envy. He did this, changed the very feeling of a room, like he was playing a note. I had been bleeding for months just for inches. My Harmony flattened the feeling. The work was what mattered.
The Archduke cut, testing whether a new sun at the rim of the roof changed anything.
It did. Just a little.
"Don’t mind me," Lucifer said. He lifted his own blade, its edge a line of pale gold, and drew a simple circle in the warm air. His power, God’s Eyes, didn’t blink. He wasn’t here to be the hero of my fight. He was here to make the floor honest.
He traced neat, warm lines of light along the stone of the roof. Sunbrands. They didn’t burn. They didn’t attack. They simply revealed. The places where the floor liked to lie for the Archduke, where the vow "Distance is treacherous" was strongest, now had a faint, chalk-like outline on the stone. The invisible paths where his after-blades preferred to drift were now traced in soft, golden light. For the first time since the fight had started, I could see the shape of the cheating.
That didn’t fix the problem. But it made my feet honest.
"Use the air," Lucifer said, like a man mentioning the obvious. "Stop letting it decide where it wants to sit." He rolled his wrist. Heat rose in one corner of the ring by a fraction, creating an updraft as polite as tea steam. The nearest veil of miasma slid sideways, like soap under running water. No brute force. Just a preference.
I saw. I hated how clean and easy it looked. I wanted to be petty about his talent. Harmony ate that feeling before it could learn to talk and left me with only the instruction. I copied the idea, but made it my own. A swirl of Aegir’s cool to make the air heavier where it hurt me. A little air hook to encourage a veil to be somewhere else. Not divine, not clever. Just practical. For origınal chapters go to 𝔫𝔬𝔳𝔢𝔩⚫𝔣𝔦𝔯𝔢⚫𝔫𝔢𝔱
The Archduke didn’t waste a second pretending to be bothered. He slid his blade through one of Lucifer’s sunbrand strands while speaking a new vow. "Edges arrive late." The strand of light popped with a sharp hiss. A new oath-scar, small and mean, walked its way along his collarbone. He had paid a price in his own power to break Lucifer’s rule and keep his own.
"Deny-start," I told myself. "Ghost bind. Short thrust. Reset. Stack the starts."
We traded. The room didn’t tilt in my favor anymore. It just stopped tilting quite so much against me. His sleeve-check found bone. Valeria cracked and complained about her fees. He used a glass ribbon under my slide; I turned it into trash with a hip shield and stepped high instead, ugly and correct. He put a pressure needle at my mid-shin; I let it roll into a Grey seam that didn’t have any feelings.
Red Hunger tried a new flavor, a warm permission to take a bow when you do something right. Harmony called it weather and refused to draw the curtains. Lucifer, from the rim, pinned something I couldn’t see in the far corner—a thin, descending filament from higher up the tower that had been making the roof hum like a guilty tuning fork. The hum eased.
The Archduke rolled the miasma into a heavy crown over my hands, a steady weight that wanted to creep into my wrists and write its own rules in my tendons. I moved my Harmony out of my spine and into those joints, making them boring and honest. The weight found nothing interesting to bully and slid off to be useful somewhere else.
Lucifer’s sunbrands weren’t permanent. They were moments of truth. He would trace a new one, showing me a safe path, and the Archduke would counter by corrupting it or paying the price to break it. It was a constant, high-level duel of rules being written and unwritten around my own fight for survival.
"All courage will shake," the Archduke said again, and the room asked my body to wobble. The sunbrands showed me the lines where that vow was strongest. I simply chose not to stand there. Harmony flattened my courage into a choice that didn’t care about applause. The shake kept tapping at my wrist. I chose anyway.
There is a point in a fight where the choreography stops being clever and turns into a budget report. The Archduke still had more to spend. But now, I wasn’t tipping the room anymore.
He finally decided to say something directly to Lucifer. He turned his head a single degree and looked at the twin crowns of white and black. "You’re late," he said.
"The door was locked," Lucifer answered, his tone mild. He didn’t move from the rim. He just kept the floor honest, for a few seconds at a time.
He didn’t need to do more. The window he’d opened was enough. It gave me enough air to breathe without paying a tax on it.
I hit the wall again—the place where my choices were running out of budget. Where you either break or you break through. I wasn’t breaking. Not yet. But the window had shown me where the doorframe was, and that was the first truly useful thing that had happened all day. Lucifer didn’t speak. He just pinned a second descending filament with a quiet sunbrand so the tower would stop humming like a guilty instrument.
He could have taken this fight away from me if he wanted to. He didn’t. He made it honest, and he left it mine.
The Archduke made one more sensible, perfect cut that would have ended most days. I met it. And I felt something inside me, something that had been holding its breath, finally stop asking for permission.
