Thiago pressed his shoulder to the damp trunk, breath cracking, as the forest closed around him; something vast moved upriver and the air tasted of hot metal and wet stone.
The village of Vila Verde had not heard such a sound in a living man's memory.
Dona Marta's warning arrived that night like a bruise: seven rearing heads, a lake of fire, rivers that ran against their banks. By dawn the elders passed fear like a cloth through the huts. Thiago—sixteen, untested, with a face that stayed too serious in moments of play—felt a pull he could not refuse.
The Dark Prophecy
Vila Verde sat along a slow, winding river. People planted by hand, traded fish before sunrise, and watched the water for small changes. Then the omens came: fish with blackened scales, a wind that smelled of hot stone, a hush where birds had nested.
Dona Marta told the council of the vision—seven heads, a roar that would swallow the valley. Elders argued over meaning and remedy, but fear moved faster than debate. Thiago rose and said, "I will go."
The council fell silent; some scoffed, others folded their hands. João only tightened his jaw and handed Thiago a cloth-wrapped knife.
The Chosen One
João had the thin body of many winters but the hands and posture of a man who had stood in battle. He taught Thiago how to set an ambush, how to find a trail by the way leaves lay, and how to make his breath small so the forest didn't mark him.
"Courage is what you do with fear," João said on the morning Thiago left. It was not a speech but a rule for one day at a time.
Thiago packed a sword, a bow, arrows, a small pot, and the little knife João sharpened each week. He wrapped a scrap of his mother's cloth around his wrist for luck and stepped into the green.
The Departure
The canopy closed like a hand; light turned the color of old coins. Vines tugged at his sleeves, and the path became a line of choices—step here, push through that, avoid the soft black mud that swallowed boots.
Night in the forest was not empty. It was full of low sounds: water on leaves, a branch's slow snap, insects that prayed in the dark. Thiago slept badly and kept the fire low so smoke would not tell the forest he was near.
Once, near a low bank, he woke to a voice threading the air like silk.
"Why do you move toward that noise?" it asked.
He sat up and saw a woman at the water's edge. Her hair moved like wet moss; her eyes shone the color of moonlight on water.
"To keep my people safe," he answered.
"You move for a clean thing," she said, each word a ripple. "Iara. I will guide you for a while."
The Forest Guardians
Iara showed him how to read the forest's small betrayals: a patch of ground trampled in a way that meant an animal had passed, a bird's call that had a question in it. She spoke in half-sentences and made Thiago listen with his whole body.
She told of the dragon's origin: a curse born of a sorcerer's hatred, hard as stone and hungry for fear. The curse held the beast and bit at the land, and each time the dragon fed on that fear the forest grew colder.
They moved toward a cliff where the waterfall dropped white into a black throat. Fog lay along the lip like breath.
At the cliff edge, Iara dipped her hand into the spray and let it catch the light. "This place keeps memory," she said. "It remembers the old quarrels."
Thiago felt small against the wall of water and large behind it at once.
The First Encounter
The mist clung like a wet cloak. The air took on the bite of sulfur and iron. Something moved in the trees, and then the world rose with seven heads, each taller than the highest house.
"Who dares enter my domain?" one head hissed, voice like stone scraping metal.
Thiago stepped forward with his hand on the hilt. "I am from Vila Verde. I will stop what harms my people."
Laughter rolled across the valley like distant thunder. The dragon struck—claws that gouged soil—and Thiago ducked and moved with the small, economy steps João had trained into him.
Iara's warning threaded through him: Aim for the eyes. They hide the beast's edge.
He drove his blade into an eye. Steam and flame shot out; the head convulsed and bled black fire, but other heads turned and struck.
