Three months in the Underworld changed Kauã in ways he hadn't expected.
Not physically—although his daily training with Hades had begun transforming his body from “boy who carried fishing nets” into “boy who might actually survive a real fight.” The change was something else. It was in the silence.
Kauã had learned to listen to silence. In the Underworld, silence wasn't the absence of sound—it was the presence of something older than sound. In the first few days, it drove him crazy. He talked to himself, sang, drummed his fingers on the table—anything to fill the emptiness. After three months, silence had become company. He heard things within it—the river flowing, the shadows moving, the pulse of the Underworld like a gigantic heart beating slowly.
And the shadows had begun to obey.
Not much. Not enough to impress Hades, who continued watching the training with the same expression as someone reading a particularly tedious report. But enough for Kauã to darken a small room for a few seconds, and enough for the shadows around his feet to move when he concentrated—not like extensions of his body yet, but like curious animals that had decided to come closer and investigate.
“You're not training today,” Hades said that morning, appearing in Kauã's doorway while Nyx tried to lick his face for the hundredth time.
Kauã pushed Nyx's right head away and looked at Hades.
“Did I die and not notice?”
“If you had died, I'd know before you did.”
“Fair enough. So why aren't I training?”
“Because you're going to Olympus today.”
Kauã froze. Nyx took advantage of the distraction and licked his ear with the dedication of someone who had found her calling in life.
“Olympus,” Kauã repeated.
“You know what it is.”
“I know what it is. I just didn't expect to go so soon.”
“It's not soon. You're my spokesperson. You need to know the place where you'll represent me. You need to meet the other apprentices. You need to learn how to walk among gods without causing a diplomatic incident in the first five minutes.”
“Two minutes, you said last time.”
“I revised my estimate. Downward.”
Persephone appeared behind Hades with a basket covered by an embroidered cloth.
“I made honey bread and walnuts for the trip,” she said, handing the basket to Kauã with a smile that suggested it contained much more than bread. “And I packed dried figs. And cheese. And a little cured meat. And...”
“He'll be gone for the day, not a month,” Hades said.
“He's a growing boy. Growing boys eat.”
“He eats more than Cerberus.”
“Cerberus has three mouths. Kauã has one. That makes his achievement even more impressive.”
Kauã took the basket. It weighed as if Persephone had put rocks inside it.
“Thank you,” he said.
Persephone held his face between her hands, as she did every time he went somewhere, and studied him with those green eyes that seemed to contain every season of the year.
“Be polite. Be kind. Don't provoke Ares. Don't look Aphrodite in the eyes for more than three seconds. And if anyone bad-mouths Hades in front of you...”
“I ignore them and keep my composure?”
“You tell me their name, and I'll take care of it personally.”
Hades sighed. It was a sigh Kauã already knew—the sigh of a god who ruled the realm of the dead and still couldn't rule his own wife.
The ascent to Olympus was different from the descent into the Underworld. Where the descent had been black stone stairs plunging into darkness, the ascent was a rocky path opening along the side of a mountain—not Mount Olympus as mortals could see it, but something overlaid upon it, like a shadow that existed in the same place but on another layer of the world.
Hades walked beside Kauã as far as the entrance. Then he stopped.
“I won't go any farther,” he said.
“You can't enter Olympus?”
“I can. I shouldn't stay away from the Underworld for too long. And I don't like going.”
There was something in that sentence Kauã couldn't ignore. It wasn't bitterness—Hades didn't do bitterness. It was something closer to weariness. The weariness of someone who had gone somewhere a thousand times and felt, every time, that he didn't belong there.
“They don't like you there,” Kauã said. It wasn't a question.
Hades looked at him. For an instant, something moved in those dark eyes—not surprise, because Hades was never surprised, but something close to recognition. As if Kauã had said aloud something Hades had carried in silence for millennia.
“They respect me,” Hades said. “Respect and affection are different things.”
“That sucks.”
“Language.”
“This is a deeply unfair and unfortunate situation.”
“Better.” Hades paused. “Hermes will meet you at the entrance. He's... tolerable. He'll show you Olympus. Don't believe everything he says, don't bet anything with him, and for the love of everything sacred, don't accept any gifts.”
“Why?”
“Hermes doesn't give gifts. He makes investments. And the interest is always higher than you imagine.”
Kauã nodded. He looked at the path rising ahead. Then he looked at Hades.
“I'll represent you well,” he said.
Hades didn't answer. But when Kauã turned to climb, he heard behind him, so softly it could have been the wind:
“I know.”
Olympus was loud.
After three months in the silence of the Underworld, the noise hit Kauã like a wall. Voices, laughter, metal striking metal, music coming from somewhere he couldn't identify, the distant roar of some creature he sincerely hoped was locked up.
And it was enormous. Not enormous like the Amphitheater of Olympia, which was large in a way the human mind could process. Olympus was enormous in a way the mind refused to accept. White marble temples rose on terraces climbing the mountain like the steps of giants. Gardens spread between the buildings—not Persephone's strange, luminous gardens, but green, living gardens exploding with colors Kauã recognized from the world above. Fountains sprayed crystal-clear water that glowed with a light of its own. Training arenas opened onto natural plateaus, and inside them, figures moved with a speed that didn't seem human.
Because it wasn't.
“Kauã Padoan! The boy from the Underworld!”
Hermes appeared out of nowhere—literally nowhere, as if the air had decided to turn into a person. He was younger than Kauã had expected, or at least he looked younger. A sharp face, golden eyes that moved far too quickly, a smile that seemed to hold three jokes at once. He wore winged sandals that floated two inches above the ground and moved with the energy of someone who had drunk the divine equivalent of ten cups of coffee.
“Hermes,” Kauã said.
“The one and only. Messenger of the gods, guide of souls, patron of travelers, merchants, and thieves. In that order. Or not. Depends on the day.” Hermes looked him up and down. “You're shorter than I imagined.”
“Everyone says that.”
“Everyone's right. Come on, I'll show you everything. Hades asked me to be your guide, which is ironic because Hades hates me.”
“He said you're tolerable.”
“Coming from Hades, that's practically a declaration of love. Let's go.”
Hermes walked fast. Not fast like someone in a hurry—fast like someone incapable of going slowly. Kauã practically had to run to keep up while Hermes pointed out buildings, explained their histories, greeted people, and stole an apple from a fruit stand, all at the same time.
“That over there is Athena's Temple. Library, strategy room, place where fun goes to die. That's Hephaestus's Forge—don't go near it without an invitation; he's territorial about his tools. Those are Apollo's Baths—the water heals minor injuries, but he charges you by making you listen to him recite poetry. Not worth it. Over there...”
“Hermes.”
“Yes?”
“Who are those people?”
Kauã pointed toward the nearest arena. Half a dozen young people were training inside. Not the way Kauã trained with Hades—alone, in silence, failing repeatedly while a god watched without saying a word. Those young people trained together, in pairs, with weapons that gleamed and movements that looked choreographed.
“Apprentices,” Hermes said, and for the first time, some of the lightness left his voice. “Mostly second-tier. Apprentices of Ares, Athena, Artemis. They train here during the day. It's part of the routine.”
“What about the Big Three's?”
Hermes smiled. It was different from his earlier smiles—less joke, more knowledge.
“The Big Three's are another story. Your brother trains with Zeus at the top of the mountain. No one sees him. And Poseidon's apprentice trains in the sea caves beneath Olympus. The three of you are... different. Everyone knows it. Everyone's watching.”
“Watching how?”
“With fear. Envy. Curiosity. Depends on the person.” Hermes glanced at him. “You're Hades's apprentice. The first in centuries. Chosen underage. People will want to know what you are. Some will want to be your friends. Others will want to test you. Learn the difference quickly.”
Kauã swallowed. He nodded.
Hermes led him through Demeter's gardens, where apprentices rested between training sessions, ate fruit that grew on trees that shouldn't exist, and talked in groups that seemed to have invisible hierarchies. Kauã felt the eyes on him. Not all of them—some ignored him, others didn't even notice his presence. But the ones who looked stared with an intensity he could feel on his skin.
“That one is Damon,” Hermes said, discreetly pointing toward a red-haired young man training alone in a corner of the arena, striking a straw dummy with methodical brutality. “Ares's apprentice. Second year. Good with a sword, better with a spear, terrible with people. Don't talk to him unless you want to lose a tooth.”
“Got it.”
“That one's Lyra. Athena's apprentice. Smarter than anyone you'll ever meet, and she knows it, which makes her equally unbearable and fascinating.”
“And that one?”
Kauã pointed toward a young man sitting beneath an olive tree, playing a lyre with his eyes closed. The music was beautiful—not beautiful like a tavern song, beautiful like a sunset, in a way that made his chest ache for no reason.
“Theron. Apollo's apprentice. First year, like you. He's...” Hermes searched for the word. “Good. Genuinely good. The kind of person who makes you feel bad for not being better. You'll probably get along.”
Theron opened his eyes at that moment, as if he'd sensed them talking about him. He looked at Kauã. He smiled—an open smile, without calculation or evaluation. Just a smile.
Kauã waved. Theron waved back.
“See?” Hermes said. “Easy. Now come on. There's one more person you need to meet, and this one won't be as easy.”
Hermes took him to the lower part of Olympus, where the marble terraces gave way to natural rock and the sound of the sea began to drown everything else out. The path spiraled down to a stone platform jutting out over a cliff. Below, the Aegean Sea stretched to the horizon, too blue, too alive, as if it were breathing.
Someone was training on the platform.
Kauã stopped.
The girl moved like water. Not as a metaphor—as a literal description. Each movement flowed into the next without pause or apparent effort, as if fighting were the most natural thing in the world. She wielded a short trident, spinning it between her hands with a familiarity that suggested the weapon was an extension of her body. Dark hair tied in a loose knot that was coming undone with her movements. Skin bronzed by sun and salt. And her eyes—when she turned and saw Kauã, her eyes were the color of the sea on a stormy day. Not blue. Not green. Something between the two that changed with the light.
She stopped training. Looked at Kauã. Looked at Hermes. Then looked back at Kauã.
“Who's this?” she said, in the same tone as someone finding an insect in their food.
“Ária,” Hermes said, in the tone of someone introducing two people he knew would either hate or love each other, and was equally interested in both possibilities. “This is Kauã Padoan. Hades's apprentice. Kauã, this is Ária. Poseidon's apprentice.”
“The Underworld boy,” Ária said. It wasn't a question.
“The one and only,” Kauã said.
Ária studied him. Not the way Hades studied him—with neither coldness nor calculation. She studied him like someone deciding whether something was worth her time. Her eyes passed over his face, shoulders, and hands, then returned to his face with a conclusion she didn't bother to hide.
“You're skinny.”
“I get that a lot. Should I be worried?”
“Depends. Do you know how to fight?”
“More or less.”
“More or less won't survive the Tournament.”
“The Tournament is four years away.”
“Four years go by fast when you're not ready.”
Kauã looked at her. She looked back. There was something in that gaze he couldn't classify—not hostility, not interest. A test. She was testing whether he would back down.
He didn't.
“Are you always like this?” Kauã asked.
“Like what?”
“Welcoming. Warm. Making people feel at home.”
Hermes made a sound that might have been a stifled laugh or a choke. Ária narrowed her eyes. For one second—a second Kauã almost missed—the corner of her mouth moved. It wasn't quite a smile. It was the shadow of a smile, murdered before it could be born.
“I'm honest,” she said. “I thought you, of all people, would appreciate that.”
“I do. I just didn't expect it to hurt this much.”
“Get used to it.”
She spun the trident, drove it into the stone beside her, and walked away without saying goodbye. Kauã stood there, watching her leave. The sea wind struck him, carrying the smell of salt, and for a moment he was back in the village—back in the smell of home, fishing nets, everything simple.
“Is she always like that?” he asked Hermes.
“Usually worse. You got lucky. She almost smiled.”
“That was almost smiling?”
“For Ária, that was practically a declaration of friendship.” Hermes slapped him on the shoulder. “Come on. I'll show you where the apprentices eat. You'll need allies, and the best way to make allies is to share food.”
“Persephone gave me a basket.”
“I know. I smelled her honey bread from three hundred yards away. Half of Olympus did. You'll be the most popular apprentice today.”
Hermes wasn't wrong.
The apprentices' dining area was on a broad terrace overlooking Demeter's gardens. Stone tables, long benches, and a confusion of voices reminiscent of the market in Olympia. When Kauã opened Persephone's basket and the smell of honey bread and walnuts spread through the air, three apprentices he'd never seen before appeared as if they'd been summoned.
Theron was first. He sat beside Kauã without asking permission, his lyre resting in his lap and a smile that seemed incapable of malice.
“Persephone's honey bread,” Theron said, as if identifying a sacred relic. “I've heard stories about this. They say it's the best thing that exists in any realm.”
“Want a piece?”
“I'd sell my lyre for a piece.”
“You don't have to. Take one.”
Theron bit into the bread and closed his eyes. The expression on his face was that of someone who had just discovered the meaning of life.
“Is this real?” he said around a mouthful. “Does this really exist?”
“Persephone makes it every morning.”
“I need to go to the Underworld.”
“You probably wouldn't like it. It's pretty quiet.”
“I'm Apollo's apprentice. Silence is what I need most. Apollo talks. A lot. About everything. Mostly about himself. Do you have any idea how many times I've heard the story about how he killed the serpent Python?”
“How many?”
“I stopped counting at forty-seven.”
Kauã laughed. Theron laughed with him. And just like that, without ceremony, without ritual, without any of the protocols Kauã had imagined existed between apprentices of gods, a friendship began. The way the best friendships begin—with shared food and an honest laugh.
Lyra appeared afterward. Athena's apprentice didn't sit—she stood beside the table, arms crossed, looking at Kauã with gray eyes that seemed to be conducting a real-time evaluation.
“You're Hades's apprentice,” she said.
“Seems like everyone knows that.”
“Everyone knows everything about everyone here. Privacy is a mortal concept.” She looked at the basket. “Is that from Persephone?”
“It is.”
“May I?”
“Sure.”
Lyra took a dried fig, bit into it with surgical precision, and chewed while analyzing Kauã as if he were a geometry problem.
“Sixteen years old,” she said. “Below the minimum age. Hades's first apprentice in centuries. Brother of Zeus's apprentice.” She tilted her head. “You're statistically impossible.”
“Thank you?”
“It's not a compliment. It's an observation. Statistically impossible things tend to be interesting or dangerous. Sometimes both.”
“And which do you think I am?”
Lyra looked at him for another three seconds. Then she took another fig.
“I'm still calculating.”
Damon, Ares's apprentice, didn't approach. He stayed in the arena, training, and every so often glanced in Kauã's direction with an expression that was neither curiosity nor hostility. It was measurement. Like a predator assessing whether something was prey or competition.
Kauã noticed. He decided not to care. Hades had taught him that reacting to every glance was wasting energy that could be used for more useful things—like eating Persephone's honey bread before Theron devoured it all.
The day passed quickly. Kauã met more apprentices than he could memorize—names, faces, gods, weapons, personalities, all blending together in a whirlwind of information. But three things stayed with him.
Theron was someone he could trust. Kauã knew it the same way he knew the sun rose in the east—not through logic, but with certainty.
Lyra was someone he needed to respect. Not out of fear, but because underestimating her was the kind of mistake you only made once.
And Ária.
Ária was something he still didn't know how to define.
At the end of the day, when the sun began to descend and the apprentices dispersed to their domains, Kauã returned to the platform over the cliff. He didn't know exactly why. He told himself he wanted to see the sunset over the sea, which was true, but it wasn't the whole truth.
She was there. Sitting on the edge of the platform, feet swinging over the abyss, her trident beside her. The wind tossed her hair to one side, and the late-afternoon light painted everything gold—the stone, the sea, her.
Kauã sat six feet away. He said nothing. He looked out at the sea.
The silence lasted a full minute. Then:
“You came back,” Ária said without looking at him.
“The sunset is nice from here.”
“It is.”
More silence. The sea struck the rocks below in a rhythm that sounded like breathing.
“There are no sunsets in the Underworld,” Kauã said.
“I know.”
“Or a sea.”
“I know.”
“There are rivers. But they're black and silent and carry souls. It's not the same.”
Ária turned her head and looked at him. For the first time, there was no test in her gaze. There was something else—something Kauã recognized because he felt it too. Longing. Longing for a simple place, the smell of salt, a life that didn't include gods and training and the weight of being something greater than you were.
“I grew up in a fishing village,” she said. “On the coast of Corinth. The sea was the first thing I saw in the morning and the last thing I saw at night.”
“Me too. A village on Ithaca. My mother sold fish in the market.”
“Mine repaired nets.”
Kauã looked at her. She looked at him. And for a moment, they weren't apprentices of the Big Three, they weren't representatives of gods, they weren't pieces on a cosmic game board neither of them had asked to play. They were two fishermen's children sitting on a cliff, looking at the sea they'd left behind.
“Your brother,” Ária said. “Zeus's apprentice. Do you two talk?”
“Not since the Initiation.”
“Three months.”
“Yeah.”
“Does that bother you?”
Kauã thought about it. Really thought about it, the way he had when Hades asked him a similar question months earlier on a stone bench in Olympia.
“Yes,” he said. It was the first time he'd admitted it out loud.
Ária said nothing. She didn't offer comfort, say that everything would be okay, or do any of the things people did when someone admitted something difficult. She simply nodded. As if she understood. As if that were enough.
The sun touched the sea. The sky caught fire.
“I'll be here again tomorrow,” Ária said, standing. “Same time. If you show up, I won't throw you out.”
“Is that an invitation?”
“It's a non-threat. Take it or leave it.”
She picked up her trident and walked away. Kauã remained seated, watching the sea swallow the sun, feeling the wind on his face, and thinking that “I won't throw you out” was, coming from Ária, probably the kindest thing she'd ever said to anyone.
He descended back into the Underworld when the first stars appeared. The way back was easier than the way there—as if the mountain knew he belonged down below and guided him home.
Hades was waiting for him at the entrance. Standing, hands behind his back, in the same posture as always. Nyx was beside him, all three heads raised, her tail wagging.
“How was it?” Hades asked.
“Loud.”
“It always is.”
“I met some apprentices. Theron, Apollo's apprentice. Lyra, Athena's apprentice. Damon, Ares's apprentice, who seems to want to kill me.”
“Damon wants to kill everyone. He's Ares's apprentice. It's part of the job.”
“And I met Ária. Poseidon's apprentice.”
Kauã said her name the same way he had said the others. Same tone, same cadence, same neutrality. But Hades was Hades—the god who read people like open scrolls, who noticed things other gods ignored, who had lived long enough to recognize every possible variation in the human voice.
Hades said nothing. But his eyes narrowed for a fraction of a second. Such a tiny fraction that a normal person wouldn't have noticed.
Kauã wasn't just anyone. Three months with Hades had taught him that the smallest reactions were the most significant.
“What?” Kauã said.
“Nothing.”
“You made a face.”
“I don't make faces.”
“You made a micro-face. A face so tiny it almost didn't exist. But it did.”
Hades looked at him for a long moment. Then he turned and walked toward the palace.
“Go eat dinner. Persephone made lamb.”
“You're changing the subject.”
“I'm telling you to eat. Those are different things.”
Kauã followed Hades, with Nyx trotting alongside him, her right head trying to lick his hand, the center head staring straight ahead with dignity, and the left head growling softly at a shadow that probably didn't exist.
At dinner, Persephone wanted to know everything. Every detail, every name, every impression. Kauã told her about Theron and the lyre, Lyra and the figs, Damon and the stares. Persephone listened with shining eyes, asking questions and laughing at all the right moments.
“And Poseidon's apprentice?” Persephone asked.
“Ária. She's...” Kauã searched for the word. “Direct.”
“Direct how?”
“Direct like a spear to the face.”
Persephone laughed. She looked at Hades. Hades ate in silence, staring at his plate and not participating in the conversation. But Persephone had known him for millennia. She saw something in his face—something Kauã didn't see, something only she knew how to read.
Persephone smiled. Not at Kauã. To herself.
Under the table, Nyx gnawed on another stolen bone. Her right head rested its muzzle on Kauã's foot. The center head slept. The left head watched the door, as always.
That night, lying in bed, Kauã stared at the stone ceiling and thought about the day. He thought about Theron and the music. He thought about Lyra and her calculations. He thought about Damon and the danger.
He thought about Leoni, somewhere at the top of the mountain, training with Zeus, being everything everyone expected him to be.
And he thought about Ária, sitting on the edge of a cliff with her feet swinging over the abyss, saying “I won't throw you out” as if it were the most natural thing in the world.
The Underworld was silent. But for the first time in three months, silence wasn't the only thing Kauã heard before falling asleep.
There was also the sound of the sea. Distant, impossible, imagined—but present.
And that was enough.
