Chapter 4 – The Obsidian Scar

The heavy reverberation of iron-shod boots multiplies across the cavern ceiling. Gwen’s holy tuning fork hums a sickening, high-frequency note that vibrates directly into the marrow of my teeth. The inquisitors are descending, fanning out across the upper ledges, casting their harsh yellow torchlight into the deep shadows.

I let my jaw unhinge slightly. The back of my throat ignites, a low, tectonic rumble building in my chest. One breath. That is all it will take. I can turn the spiraling stairwell into a vertical chimney, flash-boiling the moisture in their lungs before they even see the glow of my fire. I step forward, ready to erase the threat.

Eira’s hand clamps hard around my wrist.

Her fingers are cold, small, entirely human. I look down at her grip, then at her face. "Let me melt them," I whisper, the words dripping with sulfur.

"No." She shakes her head, her grip tightening. "If you burn them, the ambient temperature in the cavern spikes. The cathedral’s deep-wards will detect the thermal anomaly and drop the iron floodgates. We will be locked in here permanently."

She does not wait for my argument. She releases my wrist, presses her back against the bedrock, and cups a hand over her mouth. She inhales, finding the exact resonance of the holy tuning fork above, and then hums a flat, dissonant minor third. She projects the sound perfectly, bouncing it off a jagged stalactite to our left. The note warps, echoing up a false ventilation shaft on the far side of the chamber.

Above us, the boots instantly pivot. The commander barks an order, and the heavy footfalls rush away, chasing the phantom acoustic signature. I am a creature forged to crush mountains, and this choir cast-off just outmaneuvered an entire inquisitor squad with a breath.

We slip deeper into the fissure, descending beyond the reach of the iron spikes. The rough, damp basalt of the prison level smooths out, transitioning into a slick, frictionless tunnel of solid black obsidian. Eira trails her fingers along the glassy wall, her pace slowing.

"This isn’t carved," she breathes, feeling the seamless, melted ripples in the stone.

"It is a scar," I say, my voice flat, echoing off the perfect acoustics of the glass. "Three centuries ago, the first choir cornered me in a valley near the northern coast. I did not want the iron. So I breathed until the sand melted, until the river boiled, until the limestone crystallized into this."

I wait for her to flinch. I want her to pull her hand away from the wall. I want her to look at me and see exactly what is walking beside her—a beast that incinerated a settlement of three thousand humans for a single, desperate moment of freedom.

She stops walking. She stares at the black glass, tracing a hardened teardrop of melted rock. Then, she turns and looks directly at my left wrist, at the raw, silvered grooves where the iron eventually won anyway. She doesn’t pity the burned valley. She pities the fact that my fire was not enough to save me.

Before either of us can speak, the hum of the tuning fork suddenly spikes in volume. It pierces the obsidian tunnel. They realized the echo was a trick. The blinding sweep of a torch beam cuts around the bend ahead of us.

I grab Eira by the waist and haul her backward into a narrow, vertical crevice in the glass wall. It is entirely too small. My shoulders scrape the edges. I pull her flush against my front, crushing her into the dark just as the yellow light sweeps past the opening, missing us by inches.

We cannot move. Sight is entirely stripped away. There is only the suffocating confinement of the stone and the devastating proximity of her body. Eira’s chest heaves against mine. I can smell the salt of her sweat, the sharp copper of the magic she just used, the sweet, terrifying scent of her fear. Her pulse hammers a frantic rhythm directly against my sternum.

My internal temperature surges in response. My draconic blood, dormant for centuries, tries to manifest scales to armor us, but my heat is a weapon. I force the fire down, swallowing the magma rising in my throat so I do not cook her alive in this crack. She gasps, her lips brushing the pulse point at my collarbone as she struggles for air in the superheated space.

The magic in her veins is still awake, restless from breaking my locks, demanding a toll. In the pitch black, I slide my hand up her arm. I take her trembling fingers and press them flat against the base of my own throat, right over the heavy thud of my draconic vocal cords.

"A minor seventh," I murmur, my lips brushing her hair. "Inverted. Sung directly against this hollow." Her fingers twitch against my scalding skin. "Sing it, Eira. It is the override chord. It will bind my will to your voice. You won’t have to fear what my fire does."

It is a desperate, pathetic offering. A monster volunteering for a new leash just to prove she won’t bite.

Eira’s breath hitches. Her fingers rest over my fatal flaw for one long, agonizing second. Then, she curls her hand into a fist and pulls it sharply away from my throat.

"I didn’t come down here for a pet," she whispers fiercely into the dark.

The heavy boots finally pass our crevice, fading back toward the upper stairs. The torchlight vanishes. I step out of the crack, letting the cool, damp air rush between us. The ambient, bruised amber glow of the deep magma illuminates the tunnel once more.

Eira exhales a shaky breath, pushing her tangled hair back from her face with her right hand.

She pauses.

She looks down at her palm. Stretched across her lifeline, bright and angry in the dim light, is a perfect, pink scorch mark. It is a negative imprint of my collarbone, burned into her fragile human skin simply because I could not suppress my own ambient heat fast enough when I held her. She rubs her thumb over it, her expression unreadable. She doesn’t complain. She doesn’t accuse.

But I stare at the blistered skin, the realization freezing the magma in my veins. Can a creature of pure combustion ever hold something without leaving a scar?
