Chapter 1: Would You Say I‘m Worthy

Chapter Text

The field was wide enough for dragons.

Grass bent in long silver waves beneath a hard blue sky, and the wind carried the scents of salt and smoke from the distant sea. No walls. No towers. No frightened courtiers pretending not to stare.

Only sky.

Only fire.

Aerion Targaryen sat atop his dragon and tried not to feel small.

Morghul shifted at his shoulder, claws digging furrows into the earth. At three years old he was barely large enough to ride — all long limbs and restless muscle — but there was nothing ungainly in the way he held himself. Dark gray scales drank the sunlight, while white horns swept back from his skull like carved bone. Pale frills ran along his neck and down his tail, snapping in the wind like banners of war.

His breath smoked faintly.

Blue flickers danced between his teeth.

Across the field, Daemon watched them with the stillness of a drawn blade.

Behind him loomed Caraxes, the Blood Wyrm coiled upon himself in a grotesque parody of patience. His long neck curved like a question mark, crimson scales gleaming wetly in the sun. When he exhaled, the grass blackened.

Aerion swallowed.

“Again,” Daemon said.

He did not raise his voice.

He never needed to.


Aerion rested a hand against Morghul’s neck. Heat pulsed beneath the scales — a living forge, steady and familiar. Through their bond he felt the dragon’s agitation, the barely contained urge to burn, to leap, to devour the horizon.

Not yet, Aerion thought, pressing his palm more firmly to the warm hide. Listen.

Morghul’s tail lashed once, dragging a white arc through the grass.

“Morghul,” Aerion said, steady as he could make it. “Sōvēs.” Fly.

The dragon crouched, wings half-unfurling — then hesitated. His head turned, pale horns catching the light as one molten-blue eye fixed on Aerion, waiting.

Waiting for certainty.

Aerion set his jaw.

“Sōvēs.”

Morghul leapt.

Wind exploded beneath his wings. Dust and grass tore skyward as he climbed in a crooked spiral, still mastering the art of lift. His white frills snapped like sails, and for a heartbeat Aerion felt the wild, dizzying joy of shared flight — the world falling away, the sky opening its endless door.

“Control him,” Daemon called from below. “Not with hope. With will.”

Aerion tightened his grip on the saddle straps. “Lykiri.” Calm.

Morghul’s wings steadied.

The spiral smoothed into a glide.

Below, Daemon gave a single, sharp nod.

Praise.

It struck harder than any blow.


They landed in a rush of wind and flattened grass. Morghul folded his wings with a rasp of membrane and bone, shaking his broad head — a wobble of bright frills and muscle.

“Dracarys,” Daemon said.

The word fell into the field like a stone into still water.

Aerion’s heart lurched.

Morghul felt it — the spike of uncertainty, the flicker of hesitation. The dragon’s head tilted, nostrils flaring, uncertain himself.

“He will not obey a coward,” Daemon said, voice quiet as a grave. “If you fear his fire, he will too.”

“I do not fear him,” Aerion exclaimed in an instant.

Daemon’s pale eyes held his. “Then prove it.”


Aerion placed his hand against Morghul’s tense shoulder.

The scales were warm. The muscle beneath them coiled with terrible strength. His was a small dragon and yet a single careless snap could take his arm to the shoulder. He knew it. Morghul knew it.

Trust was a blade balanced on its edge.

Aerion leaned in close, hand rooted in place.

“Dracarys!”

For a heartbeat, nothing happened.

Then Morghul inhaled.

His chest expanded, ribs stretching against dark scales. Blue light flared in his throat — not the red-orange of common flame, but something hotter, stranger, alive with a cold intensity that turned the air sharp.

Fire erupted.

A lance of blue flame tore across the field, striking a line of practice targets — straw men soaked in brine — and reducing them to blackened skeletons of thin wood in an instant. The heat rolled back over Aerion in a suffocating wave, eyes watering at the impact.

Morghul roared.

Not in rage.

In triumph.


Silence fell, broken only by the crackle of smoldering straw.

Aerion’s heart pounded so hard it hurt as he slowly turned toward his father.

Daemon was smiling.

It was not a kind expression.

Rather a warrior’s smile — sharp, proud, and edged with something dangerously close to hunger.

“Again,” he said.


They drilled until the sun dipped westward.

Each command carved deeper into the bond between boy and dragon, until Aerion could no longer tell where his will ended and Morghul’s began. Exhaustion set his limbs trembling, but he did not ask to stop.

Daemon had not.

Caraxes watched it all, yellow eyes unblinking. Once, the great wyrm uncoiled and stretched his vast wings, releasing a scream that shook the clouds. Morghul answered instinctively — a smaller, courageous echo.


At last, Daemon raised a hand.

Morghul’s final gout of blue flame guttered into smoke. The dragon lowered himself to the grass with a weary huff, sides heaving. Aerion slid from the saddle, legs threatening to give way beneath him.

Daemon approached.

Up close, he smelled of steel, ash, and something faintly metallic — blood remembered by leather and mail. His gaze swept over Morghul first, assessing the set of wings, the clarity of eye, the steady rise and fall of breath.

Only then did he look at Aerion.

“You did not flinch,” Daemon said.

Aerion straightened. “No,”

A pause.

The ghost of a nod.

“Blood of my blood,” Daemon smirked.

It was not affection.

It was something older.

Something fiercer.

Aerion felt warmth bloom in his chest all the same.


As they turned toward the distant towers of Driftmark, Morghul limped after them, wings dragging faint furrows in the grass. The day’s training had pushed him to his limits, but his head remained high, blue eye bright with smoldering pride.

Caraxes slithered past, vast and terrible, his long body carving a drag path through the field. For a moment, the Blood Wyrm’s gaze met Morghul’s.

Ancient fire regarded newborn flame.

Then Caraxes rumbled — a low, approving growl that vibrated through the earth itself — and turned toward the sea.

Morghul preened.

Aerion laughed, breathless and boyish despite himself.
