The Chronos-Sentinel was no longer a graceful statue. As its Grief head lay in shattered shards on the marble floor, the remaining three heads—Joy, Wrath, and Silence—began to spin in a sickening, high-speed blur. The golden sand inside its body turned a violent, bruised purple, reacting to the "Hollow Saint" energy Matthew had forced into its system.
"It's overloading!" Andre yelled, shielding his eyes from the strobing light. "Matt, the paradox is tearing it apart from the inside, but it's going to take us with it!"
The Sentinel's four arms began to elongate, the glass stretching like pulled sugar. It didn't strike with blades anymore; it lashed out with whips of pure, condensed time. One whip cracked against the stone pillars behind the survivors, and the ancient rock didn't just break—it turned into fine sand instantly, centuries of erosion happening in a millisecond.
"We can't just hide!" Andrew roared, his voice cracking with the strain of holding his shield against the temporal shockwaves. He looked at the trembling students behind him—the ones who had lost their memories of home, their names, their very sense of self to the Sentinel's hunger. "If Matthew falls, there's nothing left to go back to!"
Inspired by the Shield of the F-Class, three C-Class students stepped forward. They didn't have much mana left, but they pooled what they had, casting a collective Aegis spell that reinforced Andrew's barrier.
Lyra, still perched high on the Sentinel's shifting shoulder, drove her fire-sword into the joint of its primary arm. "Eat this, you glass freak!" she screamed. The violet-white flames Matthew had shared with her surged, melting the glass and fusing the arm in place.
Matthew felt his vision blurring. His hands, gripped tight around the Sentinel's torso, were no longer skin and bone. They were flickering outlines of violet static. He was becoming the very thing the Architects feared: a living breach in the fabric of reality.
"You want a sacrifice?" Matthew's voice was now a thunderous roar that silenced the Sentinel's psychic shrieks. "I'll give you a world that never began!"
He reached into the center of the Sentinel's chest—straight through the glass and into the swirling hourglass core.
The moment his hand touched the golden sand, the chamber went silent. The spinning heads stopped. The whips of time froze in mid-air.
Matthew didn't pull the sand out. He poured the Void in. The black, hungry vacuum of his soul collided with the infinite "Always" of the Chronos-Sentinel. It was a collision of Nothing and Everything.
The cracks started at Matthew's fingertips and raced upward. The head of Joy exploded into dust. The head of Wrath disintegrated into a cloud of steam. Finally, the head of Silence cracked down the middle, a single, crystalline tear of mana falling to the floor.
The Sentinel's body began to glow with a blinding, terrifying heat.
"Get down!" Matthew choked out, his body trembling with the effort of containing the explosion.
With a sound like the world's largest diamond shattering, the Chronos-Sentinel blew apart.
