For parents and teachers: Equandia blends real science with magical realism. AMI, the Guardians' gifts and Umbra are fiction: in the real world no person or technology can predict an earthquake.

We recommend reading with an adult you trust. This book does not replace emergency services: in a real emergency, call your country's emergency numbers. More on fiction, safety and how it was made.

CHAPTER 3

The Screaming Wind

Gael gives instructions into a microphone from a stage and Luna raises the portable siren while people walk hand in hand to the shelter and a tornado crosses the plain

Biome: Ember Plains

Signal: Ventus (changes in wind direction)

Disaster: EF-3 Tornado

Gadgets: Crystal Anemometer, Portable Alert Siren

Lesson: Trusting local knowledge and teamwork


June arrived with dry heat and enormous skies.

Luna, now with two successful predictions under her belt, had earned a bit of a reputation in Spring Village. People greeted her in the streets. Some grown-ups asked her for advice about the weather. Others still looked at her with skepticism, as if she were a trick that would eventually be exposed.

Luna wasn't sure which was worse: the fame or the doubt.

That Friday, her third grade class took a three-hour bus trip out to the Ember Plains, an endless prairie of golden grass where the horizon stretched so far you could see the curve of the Earth. It was the time of the Annual Agricultural Fair, where farmers from all over Equandia showed off their crops, livestock, and farm technology.

Luna carried AMI, as always. And her notebook, now with sixty-three observations.

As the bus rolled along the straight road that cut across the prairie, Luna gazed out the window. The scenery was hypnotic: kilometer after kilometer of rippling grass, windmills turning lazily, silver silos gleaming in the sun. And sky. So much sky it made you feel small.

"Luna?"

She turned around. Mateo, her first ally since the day of the earthquake, was sitting in the seat behind her.

"Yes?"

"Are you going to detect any disasters today?"

There was no teasing in his voice. It was genuine curiosity.

"I hope not," Luna answered honestly.

"But if you do..." Mateo lowered his voice, "you'll warn us, right?"

Luna nodded.

"Always."


Ember Agricultural Fair - 10:30 AM

The fair was organized chaos. White tents in perfect rows. The smell of popcorn, cotton candy, and livestock. Giant tractors displayed like works of art. Kids running between the pens of sheep and cows. A stage where a country band played cheerful music.

Luna walked with her class, but her attention was somewhere else.

On the wind.

There was something strange about it.

She took out her notebook.

Friday, June 7, 10:35 AM

Biome: Ember Plains

Temperature: 28°C

Wind: from the south, moderate speed (~15 km/h)

Sky: clear to the west, cumulus clouds to the east

Observation: steady wind, no changes

She put the notebook away and tried to enjoy the fair. She ate cotton candy. She saw enormous pink pigs. She listened to a farmer explain drip irrigation systems.

But the wind kept pulling at her attention.

At 11:15 AM, it changed.

Suddenly, the wind that had been coming from the south shifted and began to blow from the west. Hard. Luna felt her hair fly to one side.

She took out the notebook.

11:15 AM - Wind shifted from south to west. Speed increased (~25 km/h).

"Luna, are you coming to see the horses?" Sofía called.

"In a minute," Luna answered, looking to the west.

The cumulus clouds had grown. And they were moving fast.

Fifteen minutes later, the wind changed again.

Now it came from the north. And it was cold. Luna felt a shiver despite the June heat.

11:30 AM - Wind shifted from west to north. Temperature dropped ~5°C. Clouds building to the west.

Three changes of direction in one hour.

Luna felt something in her stomach. Something that wasn't cotton candy.

She opened AMI and spoke in a low voice.

"I need to measure the wind: how fast it's going and which way it's blowing."

The backpack buzzed. Luna pulled out a device the size of a small bottle, made of something that looked like crystal but was unbreakable. It had a little propeller on the tip and a built-in digital compass. An anemometer: the instrument that measures the wind.

She raised it toward the sky.

SPEED: 32 km/h (RISING)

DIRECTION: North (358°)

ALERT: Abnormal changes in direction - Possible atmospheric rotation

Luna looked to the west.

The clouds were no longer just cumulus. Now they formed a wall. A dark, greenish-gray wall, with a base that seemed to hang from the sky like a curtain.

Wall cloud. Visible rotation.

"No," Luna whispered.

She ran to where Miss Mendoza was standing.

"Miss Mendoza, I need to talk to you. Now."

The teacher was buying lemonade.

"Luna, can you wait just a...?"

"NO." Luna had never interrupted an adult like that before. "Miss Mendoza, there's a tornado forming."

Miss Mendoza froze.

"What?"

"The wind changed direction three times in one hour. The clouds formed a wall with rotation. The temperature dropped suddenly. Those are the signs of a tornado. We need to get to a shelter. NOW."

The teacher looked up at the sky. The clouds did look... strange, yes. But a tornado?

"Luna, tornadoes are rare this time of year..."

"MISS MENDOZA, PLEASE!" Luna felt tears in her eyes. "If I'm wrong, we miss an hour of the fair. If I'm right and we do nothing, we could be gone."

Miss Mendoza looked at Luna and understood this was no whim. She remembered the earthquake. The river. The two times this girl had been right.

"All right. I'll gather the class."

"No." Luna looked around. "The whole fair. We need to evacuate everyone."

"Luna, I don't have the authority to..."

A shout interrupted the conversation.

"LOOK AT THE SKY!"

Everyone turned toward the west.

From the base of the wall cloud, something was descending. A bulge. A funnel. Spinning. Slow at first. Then faster.

A tornado.

And it was heading straight for the fair.


Gael shouts instructions from the fair stage as the tornado closes in and the crowd runs for shelter

11:45 AM - Chaos

Panic exploded like a bomb.

People screaming. Children crying. People running in every direction with no idea where to go.

Luna searched her memory for everything she had read about tornadoes.

Shelter: low places, away from windows, interior walls, a blanket over your head.

But here there were only tents and open fields.

"THE SCHOOL!" someone shouted. "The school has a basement!"

Luna spotted a brick building three hundred meters from the fair. Ember Elementary School. A low, solid building.

But three hundred meters was too far. The tornado was moving fast. Too fast.

Then a boy appeared at her side. He was about nine years old, with brown skin, dark wavy messy hair and brown eyes. He wore a cowboy hat and work boots.

"You're Luna Solari, right? The Guardian."

"Yes, who...?"

"Gael. I live here." He pointed at the tornado. "That's an EF-2, maybe an EF-3. We have about five minutes before it hits. The school is too far. We need the town hall shelter. It's a hundred meters north."

"Where?"

Gael pointed to a small concrete building with a flat roof.

"There. The basement is a tornado shelter. It holds two hundred people."

Luna felt instant relief. Local knowledge. Exactly what she needed. There was something strange about Gael: he smelled like wet earth after rain, even under the scorching midday sun.

"How do we organize the evacuation?"

Gael was already running toward the stage.

"FOLLOW ME!"

Luna ran after him. Gael climbed onto the stage, grabbed the microphone, and SHOUTED in a voice that didn't seem possible from a nine-year-old boy. Luna noticed it sounded like distant thunder, like earth shifting beneath her feet:

"ATTENTION! TORNADO IN FIVE MINUTES! SHELTER AT THE TOWN HALL, ONE HUNDRED METERS NORTH! RUN, DON'T WALK! LEAVE EVERYTHING! GO, GO, GO!"

Luna pulled out the Portable Alert Siren she had asked AMI for. She switched it on. A deafening, wailing sound, like the tornado sirens she had seen in videos, filled the air.

People reacted. The universal signal of danger.

They began to run toward the town hall.

Miss Mendoza gathered the twenty-four children of her class.

"EVERYONE IN LINE! HOLD HANDS! DON'T LET GO!"

Luna saw Mateo helping a little girl who had fallen. Sofía was carrying a baby whose mother was in a panic. Everyone helping.

The tornado was roaring now. A sound like a freight train, but multiplied by a thousand.

Luna looked back.

The funnel had touched down. It was massive. Easily a hundred meters wide. Spinning with a violence that defied logic. It ripped up grass, threw up soil, destroyed everything in its path.

And it was coming straight for them.

"RUN!" Gael shouted.

Luna ran. Her legs burned. The wind pulled at her hair, at AMI, at her clothes. Debris flew all around her. A piece of wood whistled past just centimeters from her head.

A hundred meters.

Fifty meters.

Twenty-five meters.

The town hall door was open. People were heading down the stairs to the basement.

Luna reached the door. She turned. Her class was twenty meters away, running in a line, holding hands.

"COME ON, COME ON!" Luna shouted.

Mateo got there first. Then Sofía with the baby. One by one, they all went in.

Miss Mendoza came last, pushing the stragglers along.

"LUNA, GET IN!"

Luna went in. Gael slammed the metal door shut with a dull thud.

"TO THE BASEMENT! NOW!"

They went down the concrete stairs. The basement was a rectangular space with thick walls, no windows, lit by emergency lights. Two hundred people packed tight. Families holding each other. Children crying. Adults praying.

"EVERYONE TO THE CENTER!" Gael shouted. "AWAY FROM THE WALLS! GET DOWN! COVER YOUR HEADS!"

All two hundred people obeyed without question, as if they recognized an authority older than reason.

Luna crouched down next to Mateo and Sofía. She covered her head with her hands.

And then the world exploded.


Luna and Gael step out of the shelter and look at the fairground flattened by the tornado

The Tornado

The sound was indescribable.

As if the Earth itself were being torn apart. A roar that rattled your bones. Pressure in your ears that made you feel like your head was going to burst.

The building above them groaned. It creaked. Luna heard windows shattering. Walls breaking apart. Things being ripped away.

Thirty seconds.

Sixty seconds.

Ninety seconds that felt like hours.

And then... silence.

Not total silence. People breathing heavily. Babies crying. But the roar was over.

"Is it over?" someone whispered.

Gael raised his head cautiously.

"Wait. Tornadoes can have several vortexes. Give me a minute."

They waited. Luna counted to a hundred in her head.

Nothing. Just normal wind.

Gael nodded.

"It's over. But stay here until I check."

He went up the stairs and opened the metal door with a creak.

Silence.

Then:

"Oh my God."

Luna ran up after him. She stepped outside.

And she stopped.

The fair was gone.

The tents, the pens, the stage, the tractors... everything had been flattened. All that was left were concrete foundations and debris scattered for kilometers. Some trees had been torn out by the roots. Others were stripped bare, without a single leaf. A car lay overturned fifty meters from the road.

But the shelter was intact. The town hall building had lost its roof, but the walls were still standing.

And everyone was alive.

"Two hundred people," Gael whispered. "Two hundred people evacuated in five minutes. Without a single casualty."

Luna felt tears on her cheeks. Not from sadness. From relief.

Miss Mendoza came out of the shelter and hugged Luna so hard it almost knocked the wind out of her.

"You saved us. Again."

"No," said Luna, pointing to Gael. "He saved us. I just saw the signals. He knew where to go."

Gael blushed.

"Teamwork."


Two Hours Later

The rescue teams had arrived. Ambulances, firefighters, news helicopters. The tornado had been classified as an EF-3, with winds of up to 265 km/h. It had flattened three kilometers of the fair and the fields around it.

And no one died. Everyone was safe. Only minor injuries: cuts, bruises, a twisted ankle.

The reporters crowded around Luna and Gael.

"How did you know the tornado was coming?"

Luna held up her crystal anemometer.

"The wind could not make up its mind: it swung three times in a single hour. And the clouds built a wall that turned on itself. Those are the classic signs of a tornado forming."

"And you?" they asked Gael.

"I grew up here. I know where the shelters are." He shrugged. "Luna saw the danger. I knew how to respond. That's why it worked."

One reporter was scribbling furiously in his notepad.

"Guardians working together?"

Luna and Gael looked at each other.

"Are you a Guardian?" Luna asked.

"Not officially. But my family has read the sky since the sky first existed." Gael smiled. "I guess that's one way of being a Guardian."

Luna felt something warm in her chest. Local knowledge. Ancient wisdom. Combined with modern science.

"We should work together more often."

"Definitely," Gael replied.


That Night - Bus Back to Spring Village

Luna gazed out the window as the bus crossed the Ember Plains on the way home. The sun was setting on the endless horizon, painting the sky orange and purple.

She took out her notebook.

Friday, June 7

Biome: Ember Plains

Signal detected: Changes in wind direction (South → West → North in 60 minutes)

Secondary signals: Wall cloud, visible rotation, temperature drop

Disaster: EF-3 Tornado (265 km/h)

Action: Evacuation to a tornado shelter with Gael's help

Result: 200 people evacuated, everyone safe

Lesson: Local knowledge is as valuable as science. Working as a team multiplies your effectiveness. You can't save everyone on your own.

Mateo sat down next to her.

"Luna, can I ask you something?"

"Sure."

"Are you scared? When you see the signals, are you afraid of being wrong?"

Luna thought about her answer.

"All the time. But I'm more afraid of NOT acting and having people die."

Mateo nodded.

"You're really brave."

"It's not bravery. It's responsibility." Luna looked at her notebook. "And I don't do it alone. Today Gael was just as important as I was. Maybe more."

Mateo smiled.

"Do you think we could learn? The rest of us and me. To read the signals."

Luna looked at him, surprised.

"You really want to learn?"

"Yes. We all do. After today... we saw what's possible when someone knows how to read the warnings." Mateo lowered his voice. "We want to help."

Luna felt tears again. But this time they were tears of hope.

"Yes," she said. "Yes, I can teach you."

She closed her notebook and looked ahead, to where Miss Mendoza was chatting with the driver.

Three disasters. Three successful predictions. Everyone safe, all told.

But most important of all: Luna was no longer alone.

She had found Gael. And now her own classmates wanted to learn.

The network was beginning to take shape.
