The first heartbeat came through the stone.
The second came through her.
The Emerald Tempest Dragon stopped in midair.
Rain hammered her wings. Lightning crawled across the black canyon walls, illuminating hundreds of ash dragons circling beneath the storm clouds.
Across from her, the Iron-Wing Tyrant stopped too.
For the first time since the battle began, the ancient creature looked afraid.
Another pulse shook the mountains.
THOOM.
The canyon walls cracked.
Ash dragons scattered from the cliffs as boulders plunged into the abyss.
The Tempest Dragon looked down.
Far beneath her, the final storm rune burned emerald against the rock.
She had opened it only moments earlier.
She thought the rune would strengthen the vortex.
Instead, something underneath the mountain had answered.
THOOM.
The Iron-Wing Tyrant roared.
“Close it!”
The Tempest Dragon stared at him through the rain.
The Tyrant had attacked her nest at dawn.
He had brought the ash dragons into her territory.
He had driven her across the canyon and tried to force her away from the ancient runes.
Now he was ordering her to close one.
“You knew.”
The Tyrant’s iron-colored wings beat against the storm.
“Close the rune.”
“What is beneath us?”
Another heartbeat rolled through the canyon.
This time the ground moved visibly.
An entire ridge rose several feet.
Then settled.
The Tempest Dragon felt cold despite the lightning burning between her scales.
That was not an earthquake.
Something beneath the ridge had moved.
The ash dragons began retreating.
Their formation collapsed as dozens turned toward the northern peaks.
The Tyrant roared at them to remain.
They ignored him.
That told her more than his words had.
His army knew what the heartbeat meant.
She did not.
The Tempest Dragon folded her wings and dropped toward the rune.
The Tyrant intercepted her.
Their bodies collided above the canyon.
Iron talons struck emerald scales.
She twisted away and released a burst of lightning.
The Tyrant shielded his face with one wing.
“Don’t go near it!”
She circled him.
“You crossed half the continent to stop me from reaching these cliffs.”
“I crossed half the continent to keep you alive.”
She almost attacked again.
Then she saw his face.
There was no mockery in it.
No triumph.
Only urgency.
“You burned my western nesting ground.”
“To drive you east.”
“You sent hunters after me.”
“To keep you moving.”
“You brought an army.”
The Tyrant looked toward the retreating ash dragons.
“I brought witnesses.”
The Tempest Dragon stared at him.
“Witnesses to what?”
The mountain answered.
THOOM.
The storm vanished.
Not weakened.
Vanished.
Rain stopped in the air.
Thousands of droplets hung motionless above the canyon.
Lightning froze between the clouds.
The Tempest Dragon’s vortex disappeared.
For one impossible instant, the entire sky became silent.
Then every suspended raindrop fell at once.
The storm returned with a deafening crash.
The Tempest Dragon nearly lost control.
Below, the final rune had split open.
A narrow passage appeared in the cliff.
Emerald light spilled from it.
The Tyrant whispered one word.
“Vault.”
She heard him despite the thunder.
“What vault?”
He descended toward a ledge.
This time she followed.
The ash dragons remained far above them.
None came closer.
The Tyrant landed beside the opening.
The Tempest Dragon landed opposite him.
The passage was enormous by human standards.
For dragons, it was barely wide enough to enter with folded wings.
Symbols covered the stone.
She recognized the storm runes.
Seven of them.
Six were dark.
The seventh glowed.
The one she had opened.
Beneath the runes was an image she had never seen.
Two dragons.
One surrounded by lightning.
One wrapped in iron wings.
Between them was a third shape.
Much larger.
Its body had been carved beneath a mountain.
The Tempest Dragon touched the image.
The heartbeat came again.
THOOM.
Dust fell from the ceiling.
She pulled her claw away.
“Who is that?”
The Tyrant did not answer.
She turned.
“Who?”
He looked suddenly older than he had during the battle.
“The reason my wings are iron.”
The Tempest Dragon looked at the metal-like plates covering him.
She had assumed they were natural armor.
Every dragon knew stories about the Iron-Wing Tyrant.
Some said he had been born beneath a dead volcano.
Others claimed he had killed the last ruler of the northern dragons and coated his wings in enchanted metal.
The Tyrant had never corrected either story.
Now he extended one wing.
“Look.”
She did.
Beneath the overlapping iron plates were scars.
Hundreds of them.
The metal had been attached to his body.
“This was done to you.”
“Yes.”
“By whom?”
“Your ancestors.”
Lightning flashed outside.
The Tempest Dragon stepped back.
“My bloodline?”
“Not only yours.”
The Tyrant looked at the carved wall.
“Mine helped.”
Long before either of them had hatched, the canyon had been a prison.
The storm dragons did not create the storms around it.
They maintained them.
The storms were part of a seal.
The iron dragons served another purpose.
They reinforced the mountains themselves.
Storm above.
Iron below.
Two bloodlines maintaining one prison.
“For what?” she asked.
The Tyrant looked at the enormous carved creature.
“The Hollow King.”
The name meant nothing to her.
That frightened her more than if it had.
Dragons remembered their enemies.
They carved victories into mountains.
They carried names through generations.
If something powerful enough to require an entire mountain range as a prison had been forgotten, someone had wanted it forgotten.
“Why have I never heard of him?”
“Because forgetting him was part of the seal.”
She stared at the Tyrant.
“That makes no sense.”
“It wasn’t magic alone.”
He touched one of the inscriptions.
“Every generation was told less.”
The dragons who built the prison knew everything.
Their children knew the rules but not the prisoner.
Their grandchildren knew only the runes.
Eventually, the storm dragons remembered the canyon as sacred territory.
The iron dragons remembered only that they should never allow all seven runes to open.
The truth became ritual.
Ritual became legend.
Legend became instinct.
Until even instinct began to disappear.
The Tempest Dragon thought about the final rune.
“Why was it closed?”
“All seven were supposed to remain closed.”
She turned sharply.
“I found six already open.”
“I know.”
“Who opened them?”
The Tyrant looked toward the ash dragons.
“That is why I brought witnesses.”
One ash dragon finally descended.
Smaller than the others.
Its left wing was torn.
It landed near the passage but refused to enter.
The Tyrant spoke.
“Tell her.”
The ash dragon lowered its head.
“We found the first rune open nine winters ago.”
The Tempest Dragon looked at the Tyrant.
“Nine years?”
“The second opened the following winter,” the ash dragon continued.
Then the third.
Then the fourth.
No dragon was ever seen opening them.
Each rune simply awakened.
The ash dragons began watching the canyon.
Three years earlier, they saw something emerge from one of the openings.
Not a dragon.
A shadow.
It crossed the cliff despite having no body to cast it.
Wherever it passed, stone became pale ash.
That was how the ash dragons received their name.
They had once been red.
The Tempest Dragon looked toward the hundreds circling above.
Their gray scales were not natural.
They were scars.
“Why didn’t you tell me?”
The Tyrant answered.
“Would you have believed me?”
“No.”
“Exactly.”
“So you attacked me?”
“I needed you away from the seventh rune.”
“You drove me directly toward it.”
“I drove you toward the eastern ridge.”
“You underestimated the storm.”
The Tyrant gave her a bitter look.
“I underestimated you.”
That was not an apology.
But it was the truth.
The Tempest Dragon turned toward the glowing passage.
“Then we close it.”
The ash dragon backed away.
“You can’t.”
“Why?”
“The runes only open.”
The Tempest Dragon approached the seventh symbol.
She pressed one claw against it.
Lightning surged through her.
The rune brightened.
She pulled away.
The heartbeat beneath them accelerated.
THOOM.
THOOM.
The Tyrant grabbed her shoulder.
“Stop.”
She shook him off.
“There has to be a way.”
“There was.”
“Was?”
“The original keepers could seal it.”
“Then we find their descendants.”
The Tyrant stared at her.
“We are their descendants.”
She understood.
Storm and iron.
Her blood.
His blood.
“Then we do it.”
“We can’t.”
“Why?”
“Because there were three bloodlines.”
The Tempest Dragon looked again at the carving.
She had focused on the two dragons.
Now she saw a smaller symbol between them.
Not the prisoner.
Something above it.
A star.
“What was the third?”
The ash dragon answered.
“Celestial.”
The Tempest Dragon had heard stories of celestial dragons.
Everyone had.
Creatures with scales like the night sky.
Dragons who navigated by stars even when clouds covered the heavens.
They disappeared centuries earlier.
Some legends said they flew beyond the world.
Others claimed they had never existed.
The Tyrant looked toward the rune.
“The last celestial keeper died before my grandfather hatched.”
“Then the prison has been failing ever since.”
“Yes.”
“Why now?”
Nobody answered.
Then the heartbeat came again.
This time the Tempest Dragon felt something inside it.
Not sound.
Recognition.
She stepped toward the passage.
The Tyrant blocked her.
“No.”
“It knows I’m here.”
“That is exactly why you don’t go inside.”
She looked beyond him.
Emerald light pulsed along the corridor.
Once.
Twice.
Matching her heartbeat.
Not the one beneath the mountain.
Hers.
She pushed past the Tyrant.
He caught her tail.
She spun.
“Release me.”
“If you enter that vault, I can’t protect you.”
“You spent the morning trying to kill me.”
“If I wanted you dead, I would have let the ash dragons overwhelm you.”
She looked upward.
He was right.
Hundreds had descended.
Only a fraction actually attacked.
The others had formed a circle.
Witnesses.
The Tyrant released her.
“Whatever is beneath us wanted the seventh rune opened.”
“And?”
“It used the one thing powerful enough to open it.”
“The vortex.”
“You.”
The word settled between them.
The Tempest Dragon looked at the glowing tunnel.
She entered.
The Tyrant cursed and followed.
The ash dragon remained outside.
The passage descended.
Every few steps, another symbol appeared.
Storm.
Iron.
Star.
Storm.
Iron.
Star.
Then the star symbols stopped.
The Tempest Dragon counted.
“Why are these missing?”
The Tyrant examined the wall.
“They weren’t removed.”
He touched the stone.
“They were never carved.”
Farther down, the storm symbols changed too.
Their circular shape gradually became pointed.
Almost like—
“Stars,” she whispered.
The Tyrant saw it.
“No.”
The Tempest Dragon continued.
The emerald glow beneath her scales illuminated the walls.
She had always believed her coloring came from the storms in which she hatched.
Now tiny lights began appearing between her scales.
Not lightning.
Points of white light.
The Tyrant stared.
“What are you?”
She turned on him.
“You tell me.”
“I don’t know.”
The second heartbeat shook the corridor.
A crack opened beneath them.
The Tempest Dragon leaped.
The Tyrant caught the opposite wall with his iron claws.
Below them was a chamber.
At its center rested something enormous.
A shape covered by stone.
The Tempest Dragon descended.
The Tyrant followed reluctantly.
The chamber ceiling disappeared into darkness.
Ancient chains stretched across the floor.
Each chain was thicker than a dragon’s body.
Most had broken.
Three remained.
One emerald.
One black iron.
One pale silver.
The emerald chain was cracking.
The iron chain was rusted but intact.
The silver chain looked untouched.
The Tempest Dragon approached it.
The silver surface reflected her face.
Then her reflection changed.
Her scales became black.
Stars burned across them.
She jumped backward.
The reflection returned to normal.
The Tyrant had seen it.
“Celestial.”
“No.”
“Your bloodline—”
“I am a Tempest Dragon.”
“Maybe that isn’t all you are.”
The chamber moved.
The enormous stone shape in the center expanded.
Then contracted.
A chest.
They were standing beside a creature so large they had mistaken its body for part of the mountain.
The heartbeat sounded again.
THOOM.
Dust cascaded from its stone-covered scales.
The Tempest Dragon looked toward its head.
Two enormous horns disappeared into the darkness.
One eye remained closed.
The other—
Opened.
There was no pupil.
Only darkness filled with distant points of light.
Stars.
The Tempest Dragon could not move.
A voice entered her mind.
Not words at first.
Memory.
She saw dragons circling the canyon thousands of years earlier.
Storm dragons filling the sky.
Iron dragons carving the mountains.
Celestial dragons descending through clouds.
Then she saw the creature beneath them.
Not attacking.
Running.
Something followed it from the sky.
Something the ancient dragons feared more.
The vision vanished.
She staggered.
The Tyrant caught her.
“What did you see?”
She stared at the creature.
“We imprisoned the wrong thing.”
The Tyrant went still.
The eye closed.
A different sound came from above.
Screaming.
They raced back through the corridor.
When they emerged, the sky had changed.
The ash dragons were no longer circling.
They were fleeing.
Clouds opened over the canyon.
Something descended through them.
At first it looked like a star.
Then another appeared.
Then hundreds.
The Tempest Dragon realized they were not stars.
They were eyes.
Massive winged shapes moved above the storm.
Their bodies were almost invisible against the black clouds.
The Tyrant stared upward.
“What are those?”
The Tempest Dragon remembered the vision.
“The reason the Hollow King was hiding.”
The mountain shook.
The sealed creature beneath them struck once against its chains.
The emerald chain snapped.
A roar traveled through the entire range.
The creatures above stopped descending.
For one moment, predator and prisoner seemed to recognize each other.
Then every shape in the clouds turned toward the canyon.
The Tyrant spread his iron wings.
“Can he fight them?”
“I don’t know.”
“Can we?”
She looked at the hundreds of ash dragons.
Then at the storm gathering around her claws.
Then at the ancient enemy filling the heavens.
“We’re about to find out.”
The silver chain beneath the mountain began glowing.
The Tempest Dragon felt the same light ignite beneath her scales.
She finally understood why the final rune had answered her.
She was not merely descended from the storm keepers.
Somewhere in her forgotten bloodline, the last celestial line had survived.
And the prison had recognized her before she recognized herself.
Another heartbeat shook the range.
This one did not come from the Hollow King.
The Tempest Dragon looked toward the northern mountains.
A second peak split open.
Then a third.
Across the horizon, ancient runes began illuminating cliffs that had never belonged to the canyon prison.
The Iron-Wing Tyrant stared.
“There are more vaults.”
The Tempest Dragon watched distant mountains begin to move.
“No.”
She remembered the final image from the Hollow King’s memory.
The celestial creatures had not imprisoned one beast.
They had driven an entire species beneath the earth.
The canyon was never a single prison.
It was the first lock in a chain stretching across the world.
The second heartbeat sounded again.
This time, something beneath another mountain answered it.
