The salt air in Hargeon didn't smell like the expensive sea breezes on the Heartfilia balconies. It smelled like gutted fish, wet hemp, and the kind of desperation that clings to a port town at midnight.
Kaelen stood at the edge of the docks, the collar of his valet shirt unbuttoned and grimy from the road. He looked at his hands; they were still clean, still the hands of a boy who poured tea and caught a falling girl. It felt wrong. Every time he adjusted his cuffs out of habit, a sharp spike of irritation hit him. That life was a skin he was trying to shed, but it was sticking to him like a scab.
He followed the vibration of the obsidian compass away from the main harbor. He eventually found the cove, a jagged tooth in the coastline where a black-sailed galley sat low in the water. There were no lights. Only the rhythmic, heavy thud of crates being dropped into the hold.
He didn't wait for a signal. He moved when the moon dipped behind a cloud, slipping over the side of the pier and dropping onto the deck like a shadow. He went straight for the hold, wedging himself between a crate of Lacrima and a coil of heavy, rusted chains.
The voyage from Hargeon felt like crossing a border into a world that had forgotten the sun. For four days, Kaelen stayed hidden in the lightless belly of the transport galley, curled between crates that smelled of salt-rot and raw, unrefined magic.
Hades had called the southern mists a "furnace," and Kaelen finally understood why. It wasn't about heat; it was about the sheer, suffocating density of the Ethernano in the air. Every breath felt heavy, like inhaling liquid metal. His lungs burned, and his head throbbed with a persistent, sharp ache that wouldn't go away.
By the time the ship's rhythm changed, signaling they were near, Kaelen felt raw and tight, his skin prickling with sparks of blue static he could barely suppress.
When the mist finally tore open, the Tower of Heaven didn't look like a building. It looked like a jagged, black bone clawing its way out of the ocean, stained by the glowing purple veins of Lacrima.
Kaelen didn't wait for the ship to dock. He knew the guards would be checking the hold once the anchors dropped. He slipped through a narrow porthole while the galley was still maneuvering, flickering across the short gap of churning water to catch a rusted iron support beam. He climbed with a silent, liquid grace, hands finding grips in the cold, wet stone.
He moved far above the reach of the overseers, finally finding a perch high in the rafters of a central chamber, shrouded by the thick shadows of a massive stone crane. He spent the first few hours just watching. The scale of the place was staggering, but so was the misery. Thousands of slaves moved like ants below him, their movements dictated by the sharp, rhythmic crack of magic-infused whips.
He adjusted the ruined remains of his silk shirt, now grey with dust and grease, and let his eyes change.
The two-tomoe Sharingan spun into existence, bleeding the world into shades of crimson. Through the eyes of his heritage, the Tower was no longer stone; it was a map of catastrophic flaws. He saw the "rusted needles" Hades had mentioned—the spatial anchors were frayed, leaking Ethernano like open wounds. The mages running this project were trying to bridge the gap to the Abyss with nothing but brute force and human sacrifice.
"They're weaving it wrong," Kaelen whispered to the darkness. He pulled a scrap of parchment from his pocket, using a tiny spark of lightning at his fingertip to char the notes into the paper. "The third level's foundation is pulling too much energy from the core. If they hit eighty percent capacity, the whole spire won't resurrect anyone. It'll just collapse under its own weight." He spent several hours taking notes and determined the construction plan for this Tower.
He had his data. He should have left right then, slipping back onto a supply boat and heading north. But as he began to navigate his way down through the internal maintenance shafts, he found himself drawn toward the lower cell blocks.
He found a vantage point in a ventilation grate, looking down into a cramped, humid cell. He recognized them from his earlier observations: the blue-haired boy, and the girl with the scarlet hair. They were surrounded by a group of smaller, trembling children.
He had spotted them a little earlier simply because their base magic was higher than the rest; they have the talent to become magic users, especially the red-haired girl.
The air in the cell block was suffocating, thick with the scent of fear. An escape attempt had failed, and everyone knew the price.
The heavy thud of boots echoed in the corridor. Kaelen watched through the grate as the guards arrived. He saw Jellal stand up, his chest heaving as he tried to take the blame. He saw the guard's cruel smile, the way he ignored the boy and grabbed Erza by the hair instead.
"No! It was me!" Jellal's shout was cut short by a staff to the gut.
Kaelen watched in silence as they dragged Erza away. He saw her look back, that small, heartbreaking smile she gave her friends. It was a look of pure, unadulterated self-sacrifice, something Kaelen couldn't quite wrap his head around. It reminded him of Ur's gaze when she sacrificed herself.
"At that age, she has the courage to do that? There was a time when he also had a pure heart, but to be altruistic in this situation, what kind of kindness is that?"
He stayed there for hours, anchored by a strange, cold curiosity. He saw Jellal slip out of the cell later, a desperate rescue attempt that he knew was doomed to fail. And he saw when the guards returned, throwing a broken, bleeding Erza back into the straw. Jellal was gone. Taken.
The silence that followed was heavy. Shô, the smaller boy, began to wail, a sound so high and thin it made Kaelen's ears ring. A guard approached the bars, shouting, his whip coiled and ready to strike through the iron.
Then, Erza stood up.
Kaelen's Sharingan flickered. He saw the change first—not in her body, but in her mana. It wasn't the steady hum of a trained mage; it was a raw, explosive spike of Ethernano, ignited by pure rage. It was only enhancing her body, and not a real power, he noticed.
"If we obey them, we die," Erza said. Her voice was low, but it carried through the entire block like a thunderclap. "If we run, we die. But if we fight..."
She looked at the guard, her eyes burning with a light that made the Lacrima torches look dim.
"WE FIGHT FOR OUR FREEDOM!" she screamed, lunging at the bars.
She didn't have a weapon, but she grabbed the guard through the iron with a strength that shouldn't have been possible for a girl her size. As she wrestled him against the bars, her voice ignited the entire floor.
"Rise up! Rise up and fight!"
The sound of other cells responding—the rhythmic banging of chains, the roar of hundreds of voices—swelled until the very stone of the Tower began to vibrate.
Kaelen stood up in the ventilation shaft, his heart thudding against his ribs. He looked down at the parchment in his hand, then at the chaos unfolding below. He witnesses a rather unexpected spectacle; a slave rebellion was certainly not planned.
The roar of the uprising was a dull, rhythmic thrumming against the stone far below, but up here, in the highest reaches of the central spire, the air was eerily still. It was a pressurized silence, thick with a magical signature that made Kaelen's skin crawl. This wasn't the messy, leaking energy of the prisoners or the crude combat spells of the guards. This was cold, refined, and predatory.
Kaelen moved through the obscure corners of the ritual chamber, his boots making no sound on the polished obsidian floor. In the center of the room, Jellal was suspended in a cage of dark, liquid-like energy. The boy's eyes were rolled back, his body twitching as the darkness seemed to whisper directly into his skull, warping his thoughts into something unrecognizable.
"Drop the spell," Kaelen said, his voice cutting through the hum of the ritual like a blade.
A figure stepped out from behind a massive Lacrima pillar. She moved with a slow, deliberate grace, her dark cloak fluttering in a wind that didn't exist. As she stepped into the moonlight filtering through the high arches, Kaelen felt his heart stutter.
He froze. His Sharingan spun rapidly, processing the image before him, but his mind struggled to accept it. The jawline, the sharp tilt of the eyes, the way her hair fell... it was a memory made flesh. It was a face he had last seen 2 years ago in the biting winds of the North, associated with a sacrifice that haunted his every step. The resemblance was so striking it felt like a physical blow to his chest.
"You??" he breathed, the word barely escaping his throat.
The woman paused, tilting her head. She didn't look like a savior; she looked like a hunter who had just found a particularly interesting prize. A small, playful smile curled her lips, and she ran a finger along the edge of her cloak, her movements slow and deliberate.
"Oh? My, what a tragic tone you have," she said, her voice a melodic, teasing lilt. She stepped closer, her eyes scanning him with a look that was both mocking and fascinated. "I'm afraid you've mistaken me for someone else."
Kaelen forced his breath to steady, his jaw tightening as he stared at her. The resemblance was haunting, but the aura was all wrong. The woman he remembered was like a frozen lake, solid, deep, and protective. This woman was an abyss.
"Release him," Kaelen commanded, the friction-lightning beginning to spark at his fingertips, a low blue hum of warning. "You're tearing his mind apart. You're going to burn out his consciousness, just let him go."
"And why would I do a silly thing like that?" she cooed, twirling a lock of hair around her finger. She glanced back at Jellal with an expression that was almost maternal, yet deeply unsettling. "He's a work of art in the making. He just needs a little... encouragement. Besides, don't you think he looks much better with a bit of conviction in those pretty eyes?"
"I said let him go," Kaelen repeated, his red eyes narrowing.
The woman let out a soft, tinkling laugh that echoed off the high ceilings. She looked at Kaelen with a newfound interest, her gaze lingering on his torn shirt and the way he stood, perfectly balanced, ready to strike.
"You're quite the intense one, aren't you? So serious. It's almost charming," she teased, stepping into his personal space. She didn't seem at all concerned by the lightning dancing on his knuckles. "I suppose you must be the one. The old man mentioned he had a certain someone under him. Kaelen, was it?"
Kaelen's eyes widened slightly. "Hades... he mentioned me?" And he even said he was working under him? That's not at all what he had agreed with Hades.
"Just a whisper," she said, her voice dropping to a playful secret. "He told me he had a very disciplined student at that estate. I expected someone a bit more... stiff. But you're much more interesting in person."
She leaned in, the scent of something floral and cold hitting his nose. "My name is Ultear. You should remember it. It's a name you'll be hearing quite often from now on."
"Ultear?" Kaelen repeated. The name was foreign to him, sounding like a strange echo, but the way she said it felt like a trap. She looks exactly like Ur, and even their names are practically identical. Ur never spoke of his daughter, but he knows she had one who apparently died. If the girl in front of him isn't Ur's daughter, he'll be Lucy's plaything for the rest of his life. He can swear on the Uchiha name that Ultear is Ur's daughter.
He was still struggling to look past her face, trying to reconcile the image of the person who had saved him years ago with the stranger standing in front of him. "I don't care who you are. I've taken the notes I needed. I've seen the flaws in this place. If you're here to oversee this, you're doing a terrible job. The slaves are taking the lower floors and the spire is a structural mess."
Ultear pouted, a mock expression of sadness that looked entirely too practiced. "So cold! And here I thought we could get along. As for the little riot downstairs... let them play. It makes for a much more dramatic backdrop, don't you think? It's all part of the process, Kaelen. Chaos breeds the best results."
She waved a hand dismissively, and the dark energy around Jellal flared, a final surge of black light snapping into the boy's forehead. Jellal's body went limp in the shackles.
"There. The seeds are planted," Ultear said, turning back to Kaelen with a sharp, dangerous glint in her eyes that replaced the flirtatious mask. "Now, listen. You have your data. Go back to your Master. Tell him the project is moving according to the new plan."
She stepped back into the dark, her form beginning to blur as she prepared to leave. "Don't get involved in the fight below. You're a tool of the Master, Kaelen. Don't waste your life on a bunch of dying children. It would be such a shame to break something as promising as you so soon."
"Wait!" Kaelen lunged forward, his hand catching only empty air and the lingering scent of her perfume.
She was gone. The ritual chamber was silent once more, save for the heavy breathing of the unconscious Jellal.
Kaelen stood in the center of the room, his heart still hammering against his ribs. He looked at Jellal, then at the spot where the woman had stood. Ultear.
He didn't understand the game she was playing, but as a massive explosion rocked the Tower from below, Kaelen realized that the report he was taking back home was going to be much more complicated than a few ruined runes.
"Lies told with kindness," he whispered, remembering Layla's voice. "There was no kindness in that woman."
He turned and leaped from the balcony, headed back toward the smoke and the screams. He could easily undo Ultear's spell on Jellal, but Hades is probably involved, so he prefers to do nothing about it.
He came here to fulfill his mission, that's all. If he were stronger, he would have destroyed this tower without a care for the consequences.
Unfortunately, he's not an hero.
