The Obsidian Vow

The wind atop the Razor Peaks didn’t just blow; it hunted. It tore at the flight leathers of the forty graduating seniors lined up on the Launch Deck, seeking any gap to bite the skin beneath.

Commander Varic “V” Slade didn’t feel the cold. He stood at the very edge of the obsidian precipice, his boots half-hanging over a three-thousand-foot drop. Behind him, the massive bulk of Kuros, his black-scaled dragon, was coiled around a spire of Star-Iron, absorbing the sunlight until the beast looked like a shadow cut from the void.

Varic waited. He let the silence stretch until it was heavy enough to crush a lung.

“Look down,” Varic said. He didn’t shout. He didn’t have to. The kinetic pressure in the air spiked—a subtle, heavy flex of his signet that shoved the command into their chests.

The seniors shuffled forward. They weren’t the trembling seventeen-year-olds who had arrived four years ago. They were twenty-one, scarred, hardened, and arrogant. But looking over the edge into the swirling mist of the Gauntlet—a labyrinth of jagged canyons that twisted through the mountain’s roots like a broken ribcage—even they looked pale.

“The Gauntlet is the final cull,” Varic said, his voice rough, like gravel grinding under a boot heel. “The currents down there change every hour. The wind shear can snap a wyvern’s wing like a dry twig. If you hesitate, you crash. If you crash, The Spire does not waste healers on corpses.”

He walked down the line, meeting the eyes of the students. He was the Wing Commander, the Master of Flight, the terrifying “Butcher.” He expected perfection because the world outside demanded it.

“Speed is your only god today,” Varic said, stopping in front of a cocky senior named Jace, who sat atop a nervous green wyvern. “You do not stop for fallen comrades. You do not slow down to navigate. You trust your beast, and you fly fast enough to outrun the gravity that wants to kill you. Is that clear?”

“Incomplete.”

The word cut through the howling wind with razor-sharp precision. It wasn’t shouted, yet it drowned out the roar of the wyverns.

Varic didn’t flinch. He suppressed a sigh that had been building in his chest for two decades. He knew that voice. He heard it in his nightmares. He heard it in the silence of his empty quarters.

He turned slowly.

Emerging from the archway of the Tactical Tower was Soraya Kaine. While Varic was armored in battered black dragon-hide and scarred steel, Soraya was a vision of severe elegance. She wore high-collared robes of deep midnight velvet, embroidered with silver threads that seemed to writhe like living smoke.

She walked toward him, her golden gryphon, Aurelius, padding silently at her heel, his eyes fixed on Kuros with a predator’s intelligence.

“Professor Kaine,” Varic said, his voice flat. “Do you have something to add to my briefing?”

Soraya stopped three paces from him. She didn’t look at his face. She looked at his shoulder, at the insignia of the Wing Commander, as if the man beneath it didn’t exist.

“You failed to mention the thermal pockets in the third sector,” Soraya said. Her voice was cool, melodic, and terrifyingly calm. “If they enter that sector at the speed you just commanded, the temperature differential will stall their mounts immediately.”

Varic’s eyes narrowed. “They are seniors, Mistress Kaine. If they cannot feel a thermal shift through their saddles by now, they deserve to stall. I am testing their instincts, not their ability to follow a checklist.”

“You are testing their luck,” she countered.

Her voice dropped an octave. The Siren signet vibrated in the air, a low-frequency hum that made the students’ teeth ache and the wyverns hiss in discomfort. “There is a difference between a test and a trap. We have spent four years training these assets. I will not have you discard them on a technicality just to satisfy your fetish for ‘hard lessons’.”

She turned to the students, dismissing the Wing Commander entirely. The shift in authority was absolute.

“Sector Three,” she commanded, her voice projecting clear and bell-like over the wind. “Bank left into the shadow of the overhang to avoid the thermal updraft. Maintain velocity, but watch your altitude. Your beasts will want to climb. Do not let them.”

She finally glanced back at Varic. Her eyes were the color of a frozen lake, beautiful and utterly inhospitable.

“Unless, of course,” she added softly, “the Commander intends to mourn another squad today.”

The accusation hit him like a physical blow.

The air between them crackled, thick with unspent Aether. The students looked between the two legends—the Unstoppable Force and the Immovable Object—terrified to breathe.

Varic felt the familiar ache in his chest, the phantom weight of a crumbling stone anchor in his hands. The bridge. She was talking about the bridge. She always was. Even twenty years later, she looked at him and saw the man who let her brother fall.

He hardened his face into the mask she expected. The mask he had worn since the funeral.

“Tactics are useless if you’re too slow to execute them, Mistress Kaine.”

“And speed is useless if you’re dead, Commander,” she replied smoothly, turning her back on him to face the drop. “Initiate launch sequence on my mark.”

Varic clenched his jaw, the leather of his gloves groaning under the strain. She hated him. God, she hated him.

And as usual, she was right.

Soraya nodded once. “Launch.”

Forty leather-winged beasts tucked their wings and dropped. The sound was like a thunderclap—a mass displacement of air that shook the dust off the Obsidian stones. They vanished into the mist of the Gauntlet.

Varic didn’t stay at the edge. He turned and strode toward the Oculus, a raised circular platform where the faculty monitored the run via magical projection.

Two figures were already waiting there.

“Ten gold on the redhead with the Scarab-Wyvern,” said a deep, booming voice. Merrick “Ric” Stone leaned against the railing, looking like a boulder that had decided to wear clothes. He was eating an apple the size of a melon with a crunch that echoed. “He’s got good hands.”

“He’s got slow eyes,” a voice chirped from the other side. Zola “Zo” Vane was perched on top of the stone railing, her legs dangling over the abyss. She was juggling three vials of bubbling purple liquid. “I put twenty on Jace. Arrogance is a great fuel source until it explodes.”

Varic stepped up to the console, ignoring Merrick’s offered apple. “Soraya just gave them the cheat codes to Sector Three. Jace will be fine.”

Soraya swept onto the platform a moment later, the velvet of her robes settling around her like armor. She stood as far from Varic as the small platform allowed.

“It’s called intelligence, Varic,” Soraya said, her eyes fixed on the shimmering air above the console where ghostly images of the students flickered. “Not everyone believes in flying blind.”

“I heard you undressed him in front of the kids, Ray,” Zola teased, catching a vial mid-air. “Careful. If you generate too much heat, you’ll set off the thermal alarms yourself.”

Soraya shot Zola a withering look, but Zola just grinned, her teeth stained slightly blue from tasting her own potions.

“Quiet,” Merrick said, dropping the apple core. He pointed at the projection. “Look at Sector Four. The shadows.”

Varic leaned in. On the magical display, the students were a blur of motion, navigating the twisty canyons. But in the deep shadows of Sector Four—the deepest part of the ravine— something was moving against the current.

“Interference?” Varic asked. “Wind shear?”

“No,” Soraya whispered, her face paling. She tapped the glass of the console, zooming the projection. “Movement. Biological. But... wrong.”

On the screen, the shadows detached themselves from the canyon wall. They weren’t shadows. They were creatures—sinuous, oil-black, with too many limbs and mouths that glowed with a sick, pale light.

“Void-Beasts?” Merrick swore, the stone beneath his boots cracking as he tensed. “Here? That’s impossible. The perimeter wards are solid.”

“They aren’t Void-Beasts,” Varic said, his kinetic sense buzzing in his teeth. “They’re faster.”

On the screen, the lead student—Jace—dove his wyvern into the turn. As he did, one of the creatures leaped. It didn’t just jump; it phased, blurring through the air like smoke before solidifying on the wyvern’s back.

The wyvern screamed—a sound that carried all the way up to the platform.

“Jace!” Zola yelled, dropping her vials.

The creature tore through the wyvern’s wing membrane in a spray of blood. The beast tumbled. Jace was thrown loose, falling toward the jagged rocks below.

“They’re targeting the mounts,” Soraya realized, her voice turning to steel. “They’re smart.

They’re hunting.”

Varic didn’t say a word. He didn’t have to.

He vaulted over the railing of the Oculus.

“Varic!” Soraya shouted.

He didn’t wait for Kuros. He fell into the open air, a three-thousand-foot drop. Mid-fall, he extended his hand. The air pressure around him slammed downward, a kinetic blast that propelled him toward the canyon floor like a human missile.

“Merrick, secure the perimeter!” Soraya barked, abandoning the console. “Zola, prep the infirmary!”

“Where are you going?” Merrick roared as the ground began to rumble at his command.

Soraya was already sprinting toward the edge, Aurelius shrieking a war cry as he dove to catch her. She leaped, her robes flying, and landed perfectly on the gryphon’s back.

“I’m going to get the boy,” she shouted, drawing a hidden dagger from her sleeve as Aurelius tucked his wings. “Before that idiot gets himself killed doing it!”

The wind roared in Varic’s ears, a deafening tunnel of sound. He was falling faster than gravity allowed, pushing himself downward with pulses of kinetic energy.

Below him, Jace was a flailing speck, tumbling end-over-end toward the razor-sharp spires of the canyon floor. The boy was unconscious, limp.

Too far, Varic’s mind calculated. Impact in four seconds.

Varic grit his teeth and shoved his hands downward. The air pressure beneath him exploded. He didn’t slow down; he accelerated, turning himself into a kinetic bullet. He caught up to Jace just two hundred feet from the ground.

Varic grabbed the boy’s flight harness with one hand and slammed his other hand toward the rushing rocks below.

Stop.

He unleashed a massive cushion of kinetic force. It hit the ground like a physical barrier, bouncing back up to meet them. The deceleration was brutal. It felt like being hit by a hammer, but it worked. They didn’t splatter; they slammed into the canyon floor, rolling through the dust and shale.

Varic groaned, spitting grit. He checked Jace. Broken arm, ribs likely shattered, but a pulse. Alive.

A screech tore through the canyon.

Varic looked up. The creature—the shadow-thing—had followed them down. It clung to the canyon wall like a spider, its body flickering in and out of existence. It hissed, and the sound made Varic’s vision blur.

He thrust his hand out, throwing a punch of pure force intended to shatter the creature’s spine.

The air warped. The kinetic blast passed harmlessly through the creature as it turned into smoke. It reformed instantly, lunging for Varic’s throat with claws that glowed with necrotic light.

Physical attacks don’t work, Varic realized with a jolt of horror. I can’t hit it.

Then, the sky turned gold.

Aurelius dropped out of the sun, a screaming comet of feathers and rage. But it wasn’t the gryphon that stopped the beast. It was the rider.

“SUBMIT.”

Soraya’s voice hit the canyon floor like a gavel. It wasn’t a shout; it was a command woven with pure Aether. The Siren signet slammed into the creature’s mind.

The beast froze mid-lunge. Its flickering form locked. It turned solid, paralyzed by the sheer weight of her will.

Soraya didn’t wait. As Aurelius swooped low, skimming the ground, she didn’t cast a spell. She didn’t weave a net.

She jumped.

She hit the ground in a roll, coming up with a fluidity that betrayed decades of muscle memory. In her hand, a dagger made of white Star-Steel flashed. It wasn’t a ceremonial blade; it was a trench knife, balanced for killing.

She moved faster than a mage should. She ducked under the creature’s paralyzed claw and drove the dagger upward, under the jaw, into the brain stem.

Black ichor sprayed across her velvet robes.

The creature didn’t scream. It dissolved, crumbling into ash that smelled of ozone and rot.

Soraya stood panting, the dagger already wiped clean and vanished back into her sleeve before Varic could even blink. She spun toward him, her eyes wide and frantic.

“The boy?” she demanded, rushing to Jace’s side.

“Alive,” Varic rasped, pushing himself up. His shoulder throbbed where he’d hit the ground. He looked at the pile of ash, then at her. “You solidified it.”

“And you caught him,” she said, her hands glowing with diagnostic magic as she assessed Jace’s injuries. She didn’t look at Varic. “If you hadn’t created that air cushion, he would be paste. And if I hadn’t locked that thing’s phase-shift, you would be headless.”

Varic stared at her. He had seen her cast spells a thousand times. He had never seen her move like that. The jump from the gryphon, the knife work—that was infantry movement. That was assassin work.

“Ray,” he started, using the nickname before he could stop himself. “Where did you learn to use a knife like that?”

Soraya stiffened. The mask slammed back into place. She stood up, her face cold and impassive, though there was a smudge of black ichor on her cheek.

“I read a book on anatomy, Commander,” she said violently. “Now, are we going to discuss my curriculum, or are we going to get this student to a healer before he bleeds out internally?”

A shadow fell over them. Kuros, the massive black dragon, finally arrived, landing with a ground-shaking thud, his jaws snapping at the air as if looking for the threat he had missed.

Varic looked at the ash again. “That wasn’t a Void-Beast. It phased through my kinetics. It was hunting the mount to get to the rider.”

“It’s evolving,” Soraya whispered, the anger draining out of her, replaced by fear. She looked up at the sliver of sky far above them. “The wards didn’t even trigger. Varic... if there are more of them...”

“Then the students are sheep,” Varic finished grimly. He looked at her, really looked at her, for the first time in years without the filter of resentment. They were both covered in dust, blood, and adrenaline.

“We need to get to the Headmaster,” Varic said, offering a hand to help her onto Kuros, since Aurelius was circling above.

Soraya looked at his hand. For a second, he thought she would refuse. Then, with a curt nod, she took it. Her grip was iron-strong.

“Agreed,” she said. “The curriculum just changed.”
