The Forbidden Void: Rise of the Untouchable Son-in-Law

Chapter 8

The descent into the lowest levels of the Spire felt like walking into the throat of a dying god.

Jaxen strode through the corridors of the sub-basement, his every footfall a death knell for the Valerius dynasty. Behind him, Seraphina followed in a daze. She had spent her entire life believing that mana was the only true currency of the universe, yet here was a man who moved through the most concentrated magical fields in the world as if they were nothing more than a light breeze.

"Jaxen, stop," Seraphina gasped, clutching her chest. Her Golden Eye was weeping tears of light. "The pressure... it’s too much. Not even my father comes down here without a Level 9 Aegis Suit. Your skin... it’s starting to smoke."

Jaxen didn't turn back. "The smoke isn't from the heat, Seraphina. It’s the world trying to fill the hole I’m making. Stay back if you want to live. What happens next isn't meant for 'Sun-Bloods' to witness."

He reached the Great Seal—the massive, circular vault door that led to the Core Chamber. It was etched with the history of Xylos, a mural of golden kings treading upon the necks of the "Null" ancestors.

Jaxen didn't use a key. He didn't even use his hands. He simply stepped forward and leaned his forehead against the cold metal.

[Void Command: Annihilate.]

A sound like a thousand mirrors shattering echoed through the sub-levels. The Great Seal didn't swing open; it disintegrated into fine, black sand.

The chamber beyond was a cathedral of gore and light. The Blood-Core, freed from the temporary dampening Jaxen had placed on it during his fight with the Shade, was now screaming. It pulsed with a violent, rhythmic crimson light that turned the air into a thick, metallic soup.

"You're back," a voice rasped from the shadows near the Core.

Jaxen’s eyes narrowed. It was the "Shade" of his father—the entity that called itself the Forgotten King. It was weaker now, its form translucent and flickering, but it still clung to the edges of the Core like a parasite.

"I told you," the entity hissed, its many voices now a pathetic whimper. "The Core is hungry. It has tasted your Void, Jaxen. It won't accept the Valerius anymore. It wants the true heir."

"I'm not here to be an heir," Jaxen said, walking toward the pulsating heart. "I'm here to be the owner."

Jaxen leapt. He didn't land on the platform; he plunged his hands directly into the crystalline surface of the Blood-Core.

The reaction was instantaneous.

A pillar of crimson and violet light erupted from the Core, piercing through the ceilings of the sub-basement, through the Royal Solar, and straight out the top of the Aurelian Spire. The entire city of Xylos shook as if an earthquake had struck.

The pain was beyond anything Jaxen had ever imagined. It felt as if his soul was being stretched across the entire city. He saw everything. He felt the millions of people in the Rust-Sinks shivering in the dark. He felt the aristocrats in the Spires clutching their jewelry. He felt the very foundations of the world groaning under the weight of the Valerius’s greed.

"Jaxen!" Seraphina screamed from the doorway, shielded only by the remnants of the Void aura he had left behind.

Inside the light, Jaxen’s body was changing. The "Null-Fibre" cloak merged with his skin, forming a set of black, organic armor that shimmered with the light of distant, dying stars. His hair, once black, turned a shocking, ghostly white.

[Evolution Complete.] [New Class Unlocked: Void Sovereign.] [Current Level: 80... 85... 89... ERROR.] [Level capped by Host’s Mortal Vessel. Resolve 'Valerius Bloodline' to unlock further.]

Jaxen pulled his hands out of the Core. The giant heart was no longer red. It was a deep, translucent purple, pulsing with a slow, steady, and terrifyingly calm rhythm. The "Blood-Core" was gone. In its place sat the Void-Engine.

He turned around. The Shade of his father let out one final, haunting laugh before it was sucked into the Engine, finally finding the peace—or the oblivion—it had sought for centuries.

Jaxen stepped off the platform. He didn't walk; he glided an inch above the floor. He looked at Seraphina. She fell to her knees, not because of gravity, but because the sheer "weight" of his existence was now too much for a Level 40 Mana-User to bear.

"The city’s heart is mine now," Jaxen said. His voice was no longer a rasp; it was the voice of the city itself. "Every light that burns, every drop of water that flows... it belongs to the Void."

"What... what are you going to do?" Seraphina whispered.

Jaxen looked upward, his gaze piercing through the miles of stone and steel. He could see Lord Valerius in the Throne Room, frantically trying to activate the Spire’s self-destruct sequence to kill everyone rather than lose his power.

"I’m going to finish the contract," Jaxen said.

With a thought, Jaxen vanished. He didn't run; he folded the space between the basement and the Throne Room and simply existed in the new location.

The Throne Room

Lord Valerius was screaming at his advisors, his golden armor dented and dull. "Why won't the Core respond?! Activate the Sun-Collapse! Burn the whole city! I will not let a Null sit on my throne!"

"The Core isn't yours anymore, Valerius."

The advisors screamed as Jaxen appeared in the center of the room. He didn't look like a student. He didn't look like a son-in-law. He looked like an ancient god of the night come to collect a debt.

Valerius turned, his face twisting into a mask of pure, unadulterated terror. He raised his staff, but the golden crystal at the top was dead. Gray.

"You..." Valerius stammered, backing toward his throne. "What have you done?"

"I've updated the terms of our agreement," Jaxen said, walking toward him. With every step, the gold leaf on the walls peeled away, revealing the cold, dark stone beneath. "You wanted a battery to take your waste. Well, I’ve taken it all. Your power, your city, your legacy."

Jaxen reached out and gripped the top of the Chancellor’s staff. With a slight squeeze, the legendary artifact—passed down through ten generations of Valerius kings—crumbled into dust.

"Now," Jaxen said, leaning in until his white-haired brow touched the Chancellor’s golden helmet. "Let's talk about my father's light and water."
