The mountain eats the sunrise.

  That's what they say about the Aerie of Vows, that the peak is so high, so sharp, it swallows the light before it reaches the valley. Standing on the Bonding Grounds with sixty other cadets, wind tearing at my braid and the taste of ice on my tongue, I believe it. The sky above us is a bruise of violet and copper, and the plateau drops away on every side into nothing but cloud and stone and a fall that would last long enough to regret your misstep.

  Bond Day.

  The day that decides everything.

  I curl my fingers inside my gloves and press my boots harder into the frost-slicked rock. Sixty cadets in formation, arranged by legacy ranking, which puts me at the back, of course, three rows behind the gleaming sons and daughters of commanders and war heroes who've never had to wonder if their name would be enough.

  Mine isn't. Not anymore.

  The wind shifts. Somewhere below the lip of the plateau, a dragon screams. Not in pain, but in hunger. The sound hits my chest like a fist, primal and enormous, and the cadet beside me flinches hard enough that his shoulder knocks mine.

  "Sorry," he mutters. His face is the color of old parchment.

  I don't answer. I'm counting my breaths the way Kal taught me. Four in. Hold. Four out. Steady. You fly with your lungs first, Li. Everything else follows.

  Kal.

  My brother's voice lives in my chest like a second heartbeat, and today it's louder than usual. He stood on this same plateau four years ago. He was chosen by a dragon so fast the instructors said they'd never seen a bond snap into place like that. Instant, inevitable, like lightning finding iron.

  Two years later, he was dead.

  Searstruck. That's the official word. They said he pushed his bond too hard, too fast. Burned through his connection to the Well until the magic ate him alive. Reckless. Undisciplined. A cautionary tale the instructors trot out when first-years get too ambitious.

  The Vale name used to mean something at the Aerie. Now it means recklessness.

  Four in. Hold. Four out.

  I didn't come here to grieve. I came here to fly.

  "Cadets." Instructor Torvin's voice cuts across the plateau like a blade on whetstone. He stands at the front of the formation, tall and iron-haired, his rider's harness worn with the particular ease of someone who stopped thinking about it decades ago. Behind him, the Bonding Grounds open into a vast natural amphitheater of wind-carved stone, and beyond that, the dragon roosts. "You have been tested, evaluated, and deemed adequate to stand before the unbonded. Some of you will walk off this plateau as riders. Most of you will not."

  A ripple moves through the formation. Fear. Anticipation. The raw, animal awareness that the next hour will define the shape of their lives.

  "The dragons choose," Torvin continues, and his gaze sweeps the rows with the flat efficiency of a man inventorying cargo. "Not you. You do not impress them. You do not perform. You stand, and you endure, and if one of them finds you worthy..." His mouth twitches. Not quite a smile. "...you will know."

  His eyes find mine for half a second. Something in them, recognition, maybe. Or the particular contempt reserved for a name that's become a synonym for failure, and then he moves on.

  I hold still. I hold everything still.

  The first dragons come over the ridge.

  There's nothing, no training exercise, no lecture, no warning, that prepares you for the sight of forty unbonded dragons cresting a mountaintop at dawn. They rise out of the mist like the mountain itself is breathing, wings spread wide enough to blot out the bruised sky, scales catching the first razor-edge of sunlight in flashes of emerald and slate and deep, furious gold. The air pressure changes. My ears pop. The temperature drops as their wings churn the thermals, and the wind that hits us carries the smell of sulfur and old stone and something electric, something that makes the fine hairs on my arms stand straight.

  The cadet beside me makes a sound like he's forgotten how to breathe.

  I haven't. Four in. Hold. Four out.

  The dragons land along the rim of the amphitheater, talons gouging stone, and the plateau shakes. They fold their wings with a sound like war drums and settle into watchful, terrible stillness. Forty pairs of eyes, slitted, ancient, burning with an intelligence that has nothing to do with human cleverness, sweep the formation.

  This is the part where you realize that everything the academy taught you about dragons was a comfortable lie.

  They are not mounts. They are not weapons. They are not partners waiting politely for a handshake.

  They are gods of the sky who occasionally tolerate passengers.

  The choosing begins without additional ceremony. A blue-scaled dragon the size of a river barge unfolds from the rim, drops to the plateau with ground-shaking weight, and walks directly to a cadet in the second row, a broad-shouldered girl named Pella whose family has held a seat on the Veyran war council for six generations. The dragon lowers its massive head, and Pella raises a trembling hand to its snout, and the bond snaps into place with a sound I feel more than hear: a low, resonant hum that vibrates in my molars.

  Pella's eyes go wide. Then wider. Then she laughs, a wild, startled sound, half sob, and the dragon rumbles something that shakes the stones under my feet.

  Another dragon chooses. Then another. The rhythm is unpredictable. Some dragons circle the formation for long minutes, scenting the air, before selecting; others stride straight to their rider as if they've known all along. A green with scarred wings picks a wiry boy from a fishing village. A silver with eyes like mercury takes the daughter of the academy's head strategist.

  One by one, the front rows thin.

  Nobody comes to the back.

  I keep breathing. I keep my spine straight and my hands still and my face empty, because I learned a long time ago that the worst thing you can do in this place is show them what you want. Want is a leash. Want is a target.

  But I want.

  Gods, I want.

  Twenty minutes. Thirty. The plateau is half-empty now, dragons and their newly chosen riders being led toward the lower grounds by grinning instructors, and the cadets who remain are trying very hard not to look desperate. The boy beside me has gone from parchment-pale to faintly green. Across the formation, I catch Zara's eye, my roommate, my only real friend in this place, who was chosen ten minutes ago by a lean copper dragon and is clearly fighting the urge to whoop.

  She mouths something at me. It's coming. Hold on.

  I don't know what she thinks she sees. From where I'm standing, what's coming is the long walk back down the mountain. The Vale name, confirmed as cursed. My mother's face when I tell her.

  I clench and shove that image down so hard my teeth ache.

  The remaining dragons, maybe a dozen, have lost interest in the formation. Most are grooming or dozing on the rim, their enormous bodies radiating heat like forge stones. It's over. The instructors are already beginning to gather the unchosen, their voices carefully neutral, professionally kind in the way that makes it worse.

  Stolen content alert: this content belongs on Royal Road. Report any occurrences.

  And then the ground shakes.

  Not from a landing. From below.

  The vibration starts deep in the stone, a bass note that climbs through my boot soles and up my shins and settles in the pit of my stomach. The remaining dragons go rigid. The dozing ones snap awake, heads swiveling, nostrils flaring. Something is coming up from the lower roosts, the deep ones, the old caves where the ancient dragons sleep in darkness so complete that instructors don't bother mapping it.

  "What..." the nearby boy starts.

  The plateau cracks.

  Not breaks. Cracks, a single fissure splitting the stone ten paces in front of me, and from it rises heat. Real heat, the kind that warps the air, that makes sweat bloom on my skin despite the mountain cold. The smell of burnt air hits me like a wall.

  He comes through the mist.

  Bronze. Not the polished, pretty bronze of parade armor, the bronze of old shields, battered and dark, streaked with verdigris and the memory of a thousand battles. He is enormous, bigger than any dragon on the plateau by a full wingspan, and his scales are scarred. Deep gouges cross his flanks. One horn is cracked halfway down. His wings, when they spread, blot out what's left of the sunrise, and the membranes are torn in places, patched with scar tissue that catches the light like stained glass.

  He is the ugliest, most terrifying, most magnificent thing I have ever seen.

  The remaining cadets scatter. They don't decide to. Their bodies simply refuse to hold position in the presence of something this ancient and this clearly unimpressed by the ceremony it has interrupted. Even the instructors fall back, and I catch Torvin's face as the dragon passes him: shock, then something colder. Calculation.

  I should run. Every survival instinct I have is screaming at me to run.

  I don't.

  The dragon's head swings toward me. His eyes are the color of a storm seen from above, grey and gold and shot through with lightning. They fix on me with an intelligence that is not human, that has never been human, that makes human intelligence feel like a candle held up to the sun.

  Stone eroding. Pressure building. The taste in the air of lightning before a strike.

  The bond-echo hits me like a wave of freezing water. I gasp, can't help it, and my vision whites out for a heartbeat, two, and when it comes back the dragon is right there, his massive scarred head level with mine, close enough that I can feel the furnace-heat of his breath on my face. His nostrils flare. He smells me. He tastes the air around me.

  The plateau is dead silent.

  I raise my hand.

  It's trembling. I don't care. I don't care about the silence or the staring or the fact that half the instructors look like they've seen a ghost and the other half look like they're about to draw weapons. I raise my hand and I press it to the flat of his snout, and the scales are hot and rough and alive under my palm.

  The bond snaps into place.

  It's nothing like what the lectures described. It's not a handshake. It's not a gentle merging of consciousness. It's a detonation, a door blown off its hinges in the deepest part of me, and through it pours something vast and ancient and furiously, achingly aware. I feel his heartbeat in my wrist. I feel his wings in my shoulder blades. I feel the weight of his years, decades, maybe centuries, pressing against my mind like the ocean pressing against a sea wall, and for one terrifying moment I think it will break me, that I'm not strong enough, that the wall will crack and I will drown in everything he is.

  Storm. Rising. Hold.

  I hold.

  The bond settles. Not gently. It settles the way a mountain settles after an earthquake, with aftershocks and grinding stone and the promise that nothing will ever be the same shape again. But it holds. I hold.

  The dragon, my dragon, Scyllax, and I don't know how I know his name, only that it's carved into the bond like letters cut in granite, Scyllax makes a sound. Low. Not a growl, not a purr. Something older than both.

  Approval.

  "Impossible." Torvin's voice, stripped of its authority, raw with something that sounds almost like anger. "That dragon hasn't chosen a rider in..."

  "Forty-three years." Another voice. Deeper. Colder. The kind of voice that doesn't need volume because the silence around it is so complete.

  I turn, my hand still on Scyllax's snout, and see him for the first time.

  Commandant Dray stands at the edge of the plateau in full dress uniform, his expression carved from the same stone as the mountain. He is watching me with eyes that miss nothing and give back less. Behind him, arranged in a perfect formation that makes the other cadets look like scattered livestock, stands the senior wing, the Aerie's best riders, the ones who've already proven themselves in the sky.

  At their head, one step ahead of the rest because even standing still he looks like he's leading a charge, is Kade Dray.

  I know him the way everyone at the Aerie knows him. The Commandant's son. Top flyer. First in every ranking, every drill, every competition since the day he bonded three years ago. He flies an obsidian war dragon named Iskra who moves through the sky like a living blade, and the cadets who've trained against him say it's like dueling a thunderstorm. Beautiful, terrifying, and absolutely futile.

  He is also, by every account I've ever heard, a bastard of the highest order.

  The problem—the one I notice before I can stop myself—is that he looks exactly like the academy's stories about him. Not in the way of portraits, where everything is arranged to flatter. He looks like someone who has never once considered how he appears to anyone, and it turned out like that anyway. Tall. Dark hair wind-whipped across his forehead, completely unbothered by it. A jaw like it was cut rather than grown. And the scar through his left eyebrow that should diminish him somehow. But it does not, not even slightly.

  I catalogue this the way I would catalogue a threat. Because that's what he is.

  But there's a half-second, just one, the length of a single missed breath, where my mind does something I don't sanction. Where it stops counting threats and just... looks. Where I think: if Kal had lived, he probably would have hated this person on principle, and then asked me what I thought of him when no one was watching.

  I shove that thought down so hard I feel it bruise.

  Right now he's watching me with an expression I can't read. Something between contempt and shock and a third thing, buried deep, that his face shuts down before I can name it. His jaw is tight. His dark hair is wind-whipped across his forehead, and his sharp, grey eyes don't blink.

  The Commandant speaks. "It seems we have our final pairing of the day." His tone suggests he's discussing weather patterns, not a moment that just rewrote every expectation in the Aerie. "Instructor Torvin, log the bond. Scyllax and..." He pauses, just long enough for the silence to cut. "Cadet Vale."

  The name lands like a stone in still water.

  I feel the ripple. The whispers start immediately. Vale, that's the Searstruck one's sister, isn't it, what is she doing here, how did she...

  Scyllax's growl stops them dead.

  It starts low, a vibration more felt than heard, and it climbs until the stones under our feet hum with it. Every dragon on the plateau goes still. Every human being goes stiller. The message is clear, primal, and requires no translation: Mine. Question it and burn.

  The whispers die.

  But Kade Dray doesn't look away.

  He takes a step forward. Then another. His dragon, Iskra, a nightmare of polished obsidian scales, sleek and perfect where Scyllax is scarred and ancient, shifts behind him, her tail curling with predatory interest. The senior riders part for him without being asked.

  He stops three paces from me. Close enough that I can see the scar that cuts through his left eyebrow, the hard line of his shoulders under his flight leathers, the way his hands hang loose at his sides with the particular stillness of someone who's learned to make his body a weapon.

  His gaze drops to my hand on Scyllax's snout. Then lifts to my face.

  He is, I decide with something that is not warmth and absolutely not interest, the most infuriating kind of dangerous. He knows it. I can sense it from the flexing of his chest in front of me.

  "A Vale." He says it quietly, but the plateau carries sound like a cathedral, and every soul on the mountain hears him. "On Scyllax."

  I don't flinch. I don't drop my hand. I don't give him a single damned inch.

  "That a problem?" I say.

  His mouth curves. It's not a smile. It's the expression of a blade being drawn. Slow, deliberate, and edged with something that isn't quite cruelty but lives in the same neighborhood.

  "Your brother acted like he had something to prove, too," Kade says. "Look how that ended."

  The words hit my heart like a lance strike. Clean. Precise. Designed to wound.

  But… He said it the way you'd say something you've rehearsed too many times. Smooth on the surface, but underneath there was a catch. Like the word cost him something.

  Behind me, Scyllax's growl deepens into something that vibrates in my teeth. I feel his rage through the bond, white-hot, ancient, a dragon's fury at seeing his rider threatened, and it takes every scrap of control I have not to let it consume me. Not to let it show.

  Four in. Hold. Four out.

  I meet Kade Dray's grey eyes and I hold them, and I pour everything I am into the stillness of my face, the grief, the fury, the bone-deep determination that has kept me climbing this mountain every single day since they buried my brother's empty saddle.

  "I guess you'll get to watch," I say.

  Something flickers in his expression. Fast. Gone before I can catch it. He holds my gaze for one more heartbeat, long enough that the air between us feels like the space between a struck match and the flame, and then he turns and walks back to his formation without another word.

  Iskra's tail snaps once against the stone as she follows.

  The Commandant is already moving on, already issuing orders, already converting the chaos of a legendary dragon's choosing into neat administrative procedure. Torvin is scribbling in a log book, his face locked in an expression I can't read and don't trust.

  But I'm not watching any of them.

  I'm watching Kade Dray's back as he disappears into the senior wing, and I'm thinking about the thing I saw in his eyes in the half-second before his mask slammed shut.

  It wasn't contempt. It wasn't shock.

  It was fear.

  Scyllax presses his snout harder into my palm, and through the bond I feel something that might be laughter. Old, dry, and merciless

  Good, the bond-echo seems to say. Let them fear.

  I curl my fingers against his scarred scales and lift my chin.

  Bond Day is over. The war has just begun.
