The night air was a cold blade against my skin as I moved through the rooftops of the Gangnam district. I wasn't using the streets; the streets were full of eyes, both human and electronic. Instead, I flickered through the shadows of skyscrapers, using [Aether Step] to bridge the gaps between cooling towers and helipads.
Every time I used the skill, the world felt less like a solid reality and more like a fragile tapestry. I didn't feel the wind; I felt the friction of the spatial fabric resisting my movement.
[Notice: 'Aether Step' is becoming more efficient.]
[Sovereign's Insight: Your body is adapting to the vacuum of the Void.]
I landed silently on the edge of a water tank overlooking an abandoned warehouse district. Below me, a sleek silver sedan sat idling under a flickering streetlamp. It was Sae-rin's car.
I didn't descend immediately. I activated [Dragon's Eye].
The world turned into a monochrome landscape of energy. I saw Sae-rin's signature—a sharp, crystalline blue pulse centered in the driver's seat. But then, I saw the "bugs." Three spectral blue threads were attached to the car's chassis, thin as spider silk. They weren't GPS trackers; they were [Mana-Resonance Tracers], the kind used by the Hunter Association's Internal Affairs Bureau.
"They really are watching her," I whispered.
I dropped from the tank, folding space mid-air so I landed directly beside the driver's side window without a sound. Sae-rin jumped, her hand instinctively flaring with frost before she realized it was me.
"You're going to give me a heart attack," she hissed, rolling down the window. "And you're late."
"I had to clean up a mess at the Han-gyul estate," I said, leaning against the car. I didn't tell her I'd nearly folded an S-rank heir into a pretzel. "Sae-rin, don't get out of the car. And don't look at the rear bumper. You're being tracked by the Association."
Her face went pale, but she didn't look back. She was a professional. "Internal Affairs? Why? My father's guild has a clean record."
"It's not your father they're interested in. It's the fact that a B-Rank Gate unraveled in ten minutes while you were inside with an F-rank porter," I said. "Your message to me was intercepted, too. If we talk here, we're talking to them."
Sae-rin gripped the steering wheel. "Then why did you come? If they're tracking the car, they'll see you."
"They see a flickering F-rank signature," I reminded her. "To them, I'm just a 'Dud' student you're pitying. But we can't stay here. Drive to the Han River park. The open space makes it harder for them to plant stationary listening wards."
The Han River: 3:30 AM
We walked along the concrete embankment, the dark water of the river reflecting the neon lights of the city. We looked like two students out for a late-night stroll—a common sight in Seoul—but the barrier I had quietly erected with [Spatial Distortion] ensured that our voices wouldn't travel more than three feet.
"The stones," Sae-rin said, handing me a small, velvet pouch. "There are five Rank-A crystals in there. It's all I could skim from the guild's monthly quota without my father's accountants noticing."
I felt the weight of the pouch. The [Eternal Solar Core] in my chest gave a hungry throb.
[Notice: High-Grade Mana detected.]
[Estimated Synchronization Gain: +0.6%.]
"Thank you," I said, tucking the pouch into my hoodie. "Now, what was the message about? You said the man in the obsidian armor... you found something?"
Sae-rin stopped walking and looked out at the water. "My father's research team did a deep-scan of the footage I 'found' in the Grade-A Gate last month. They couldn't identify the metal of his armor, but they found a match for the banner he was carrying in an ancient text recovered from a 'Lost Gate' in Egypt ten years ago."
She pulled out her phone and showed me a grainy image of a stone tablet. It depicted a dragon coiled around a fractured globe—the same image from the banner.
"The text calls them the 'Vanguard of the Void'," she said. "They aren't monsters, Jin-woo. They're a precursor race. The text says they don't invade worlds—they 'harvest' them once a Sovereign awakens. They wait for the Marrow to be consumed, and then they come to take the Core back."
I felt a cold sensation in my gut. "So the Gates... they aren't just random dungeons. They're a countdown."
"Exactly," Sae-rin said. "And the man who knelt to you? He wasn't showing respect. He was marking his territory. He was telling the other Vanguards that the Sovereign is his to harvest."
I looked at my hand. The black scale I'd consumed earlier had given me 2,000 credits, but it had also given the System a "taste" of the enemy.
[Warning: Resonance detected.]
[The 'Vanguard' signature is approaching the local sector.]
"They're coming sooner than I thought," I muttered.
"Who?"
"The ones who want the Core," I said. I turned to Sae-rin, my golden eyes flashing. "Sae-rin, the Association is tracking you because they think you're hiding a secret weapon. They think you are the one who cleared that B-rank Gate. But if they find out it's me... they won't protect me. They'll hand me over to the Vanguard to stop the 'Harvest'."
"I won't let them," she said firmly. "My guild has political connections. If we can get you to 10% synchronization, you'll be strong enough to be classified as a National-Level Hunter. Even the Association wouldn't dare touch you then."
"10% is a long way off," I said. "I'm only at 4.2%. I need more than stones, Sae-rin. I need a High-Rank Gate. A 'Red Gate'."
Sae-rin gasped. "A Red Gate? Jin-woo, those are death traps. Even S-rank teams go missing in those. The spatial stability is zero."
"I am spatial stability," I said. "In a Red Gate, the Association can't track us. The mana-jamming is too thick. It's the only place I can go all out without the 'Mask' failing."
Sae-rin looked at me for a long time. She saw the 12th-grader who was supposed to be studying for exams, but she also saw the Dragon that was slowly consuming him.
"There's a Red Gate opening in the Incheon harbor district in three days," she said quietly. "It's been classified as a Grade-A threat. The Association is looking for 'Volunteers' because no guild wants to risk their S-ranks before the World Summit."
"Sign me up as a porter again," I said. "And you... you be the 'Genius' who leads the raid."
"Jin-woo, if we fail in a Red Gate, we don't just die. We get erased from existence."
"Then we won't fail."
The Association's Internal Affairs Office: 4:00 AM
A man with graying hair and a sharp, military suit sat in a darkened office, watching a holographic display. On the screen, two glowing heat signatures were walking along the Han River.
"The audio is still jammed, Director," a technician said, typing furiously. "The F-rank boy is using some kind of low-level thermal equilibrium to distort the sound waves. It's a common trick for fire-type duds."
"A common trick?" Director Song narrowed his eyes. "Since when does an F-rank student have the presence of mind to jam an Association-grade directional microphone while talking to the heiress of the Yoo-Hwa Guild?"
"Sir, he's a 'Limit Breaker.' His circuits are fried. He's probably just paranoid."
Director Song didn't look convinced. He zoomed in on Jin-woo's face. The boy looked exhausted, his shoulders slumped, but there was something in his eyes—a stillness that didn't match his rank.
"Check the boy's background again," Song commanded. "Everything. His mother's medical records, his primary school grades, his search history. And get me a sample of the mana-residue from that B-Rank Gate. I don't care if the Yoo-Hwa Guild cleaned it; find a single grain of dust."
"Yes, Director. But why the interest in a Dud?"
Song stood up and walked to the window, looking out at the city. "Because the 'Vanguard' tablets don't talk about a girl with ice powers. They talk about a Shadow that walks between the worlds. And if that shadow is hiding in our Academy, I want to know if he's the one who's going to save us... or the one who's going to end us."
Jin-woo's Apartment: 5:00 AM
I slipped through the window of my room, the silent hum of [Aether Step] fading as I landed on the worn carpet.
I sat on the bed and pulled the velvet pouch from my pocket. I poured the five Rank-A stones onto my palm. They were beautiful—deep, pulsating violet.
[Synchronization Process: Initiated.]
I closed my eyes and let the Core feed. I felt the heat rising, the familiar burn of the Dragon's Marrow as it reshaped my DNA.
[Synchronization: 4.2% -> 4.8%.]
[New System Function Unlocked: 'Sovereign's Command'.]
[Passive: You can now communicate with 'Gate-Spirits' and 'Low-Rank Monsters'.]
I lay back, my heart beating like a war drum. In three days, I would enter a Red Gate. I would face the Vanguard. And I would finally find out if I was a human playing at being a god, or a god trapped in a human's life.
As I drifted into a restless sleep, I heard a voice—not the System's, but something deeper, echoing from the Core.
"Eat, little Sovereign. Grow fat on their light. For when the Great Gate opens, the feast will be you."
