The Third Floor of the Sunken Vaults was no longer a tomb. It was a factory.
Deep in the Abyssal Forge, the Obsidian Magma-Smith—whom Kaelen had named Ignis—stood over a massive anvil of enchanted basalt. His hammer-hand fell with the rhythmic force of a falling star. Clang. Clang. Clang.
He wasn't just melting metal; he was stripping the "Holy" enchantments from the dawn-steel of the First Legion and replacing them with the dark, caustic mana of the Cataclysm Core. The result was Aurelian-Steel: a matte-black alloy that rippled with faint, violet veins. It was lighter than iron, harder than diamond, and hungered for the life-force of those it struck.
Kaelen stood on a balcony overlooking the forge, watching his twenty-five Scale-Guards being outfitted in the new plate armor. They looked like shadows given physical form.
"Lord Kaelen," Prime's voice hissed from behind him.
Kaelen didn't turn. His [Heat Sense Lvl 2] had already picked up the subtle thermal signature of his vanguard leader, along with something else—a strange, flickering coldness in the air near the ventilation shafts.
"The air in the Siphon Block has changed," Prime reported, his new black-plate armor clinking softly. "The prisoners are restless. They claim to hear whispering in the stone."
Kaelen's slit pupils narrowed. "Whispering? Or the sound of a shadow stepping through the veil?"
He turned slowly, his twenty-foot tail coiled in a defensive spiral. "Valerius knows he cannot break my walls with an army. So, he has sent his most expensive tools. The Shadow-Step Assassins."
[ALERT: Stealth Intrusion Detected.] [Sector: Second Floor - The Whispering Gallery.] [Signatures: 3 Unknowns. Class: Void-Stalker (Level 35-40).]
Kaelen felt a cold thrill. Level 40 assassins. These were the elite of the elite, men who could walk through solid walls and kill a king in a crowded room. To them, a Naga—no matter how regal—was just an oversized target.
"Prime, stay here. Defend the Forge and the Core," Kaelen commanded. "This is not a battle for a phalanx. This is a hunt between predators."
"But Lord—"
"I was a ninja before I was a snake, Prime," Kaelen said, his dual-toned voice dropping into a whisper that chilled the Magma-Smith's heat. "I invented the shadows they think they own."
The Whispering Gallery was bathed in its usual ghostly blue moss-light.
Three figures moved through the chamber, not as physical bodies, but as ripples in the air. They wore suits of "Void-Silk" that absorbed all light and sound. They didn't trigger the floor plates. They didn't breathe the hallucinogenic spores.
"Target is in the lower vaults," the lead assassin signaled through a hand-sign. "High-tier Naga. Royal soul. Priority: Extraction of the Soul-Gem or total decapitation."
They reached the center of the gallery, near the weeping angel statues. Suddenly, the lead assassin stopped.
The blue moss-light flickered.
From the vaulted ceiling, a voice echoed—not the dual-toned hiss of a monster, but the refined, icy calm of a prince.
"You are late. I expected you three hours ago."
The assassins reacted instantly, dropping their stealth veils and drawing black-glass daggers that hummed with Void magic. They stood back-to-back, scanning the darkness.
"Show yourself, beast!" the leader hissed.
Kaelen descended from the ceiling, but he didn't drop like a heavy weight. He used his tail to wrap around a chandelier, lowering his humanoid torso into the faint light. He held Elian's enchanted daggers, now reforged with Aurelian-Steel and dripping with a Level 2 Neurotoxin.
"I have spent a lifetime studying the geometry of the dark," Kaelen said, his golden eyes glowing with a terrifying intensity. "You move with grace, but you leave a trail of mana like a bleeding wound. In my dungeon, I am the air you breathe."
The three assassins lunged simultaneously. One went high, two went low. They were Level 40; their speed was a blur.
Kaelen didn't parry. He engaged his new Tier 1 skill: [Serpent's Reflexes].
The world slowed down. He saw the path of the glass daggers. He saw the subtle tension in the assassins' muscles. He whipped his twenty-foot tail in a violent, horizontal arc.
CRACK.
The tail didn't just hit them; it carried the force of a battering ram. The two low-aiming assassins were thrown across the room, their ribs shattering despite their high-tier gear.
The leader, however, had used a [Shadow-Step] to teleport mid-air, appearing directly behind Kaelen's head. He drove his glass dagger toward Kaelen's exposed neck.
"Die, monster!"
Kaelen didn't turn his head. He didn't have to.
A wall of black, metallic scales suddenly erupted from his back—[Aurelian Plate Shift]. The glass dagger struck the copper-threaded scales and shattered into a thousand useless shards.
Kaelen spun his upper torso 180 degrees, his humanoid spine popping with a terrifying flexibility. He grabbed the assassin by the throat with his clawed hand and drove his own Aurelian-Steel dagger into the man's gut.
"The King sent assassins to kill a Prince," Kaelen whispered into the man's ear as the neurotoxin began to liquefy his internal organs. "But he forgot that a Prince who dies and returns... is a God."
[Enemy Defeated: Void-Stalker (Level 40)] [Experience Gained: 5,000 EXP]
The other two assassins, coughing blood and realizing the target was far beyond their pay grade, tried to activate their escape scrolls.
"No one leaves my Vaults without paying the toll," Kaelen hissed.
He slammed his tail onto the floor, and the [Shifting Wall] traps he had set weeks ago slammed shut, sealing every exit. The blue moss-light turned blood-red.
"Welcome to the end of your contract.
