Location: Subsurface Vault Core, Titan
Ava's eyes remained shut, the neural tether feeding surges of raw harmonic data into her mind. She hovered inches above the ground, her body trembling as if on the edge of disintegration. Around her, the vault's walls rippled like liquid obsidian, responding to her intent.
David knelt beside her, watching the readouts spike beyond safe thresholds. "She's pulling too much. Ava, stop—your vitals—"
"No," she whispered, voice distant and layered. "This is what I was born to do."
Elias and William scanned the outer perimeter. Echo One had taken position just beyond the energy dome, silent, calculating. The corrupted entities circled like vultures. Their movement had slowed—but not because they were retreating.
"They're waiting," Elias muttered.
"For what?" William asked.
"For her."
Anderson moved toward Ava. "What is the Second Gate?"
Ava's eyes snapped open. Pale blue light poured from her pupils. "It's where the first version of the Formula was hidden—not on Earth, not even Titan. But in transit… encoded into a relay vessel. One last contingency Dr. Z built in."
The chamber began to quake. Above, the sky fractured with light—Saturn's rings warping as if viewed through a kaleidoscope.
Elias cursed. "Temporal distortion. The vault's calling something across the divide."
David's fingers flew across his console. "Whatever's coming, it's massive. Mass displacement in the upper ionosphere. We've got—" he paused, blinking, "—we've got an object arriving from outside the solar system."
A shape shimmered into view beyond Titan's stratosphere. A vessel unlike anything seen before. Organic and crystalline, elongated like a comet wrapped in vine-like filaments. It pulsed in rhythm with Ava's heartbeat.
"The Archive Vessel," she said softly. "Dr. Z hid it where no one would look—in motion, forever evading prediction."
Echo One raised its arm. The corrupted army responded.
"They mean to destroy it before we reach it," William warned. "If we lose that vessel—"
"Humanity loses its choice," Anderson finished.
The protective dome faltered. One of the corrupted hybrids breached the outer shell, only to be vaporized by an automated turret. But more followed.
Ava looked up. "I need to get to the Archive."
David frowned. "We have no ship that can match its current velocity or phase drift."
"We don't need to match it," Elias said, adjusting his gauntlet. "We ride the recall pulse. Ava, you'll have to synchronize us with the vessel's temporal fold."
Ava nodded. "Prepare the others. Only four can come."
Anderson turned to William, David, and Elias. "We're going."
The floor split apart, revealing a chamber below filled with concentric rings of glowing energy. The team entered the transport cradle. Ava joined them, still linked to the vault.
Outside, Echo One stepped forward at last.
A voice boomed—not spoken, but felt within every molecule.
"Deviation must cease. The loop will complete."
The vault responded with a final surge.
Reality folded inward.

Location: The Archive Vessel - Relay Theta Prime
The team emerged into a corridor of living crystal. Data flowed through the walls like veins. Every step echoed with ancient whispers—memories embedded in the architecture.
Ava led them through. "This place… it's Z real legacy. The formulas, yes—but also the counter-arguments. His debates with himself. Every version of the future he feared."
They reached the central core: a chamber containing a spiral helix suspended in light. Inside the helix—seeds. Vials of different-colored solutions.
David gasped. "They're versions of the Formula. Dozens of them."
"Not all of them safe," Elias added, pointing to blackened vials.
Ava approached the terminal. "We only need one—the stabilizer strand. With it, we can overwrite Echo One's influence and give people back their free will."
William stepped back. "So this is the decision point."
Anderson looked at the vial marked 'Z3-Kairos.' "It's what my great-grandfather left for us."
A tremor shook the vessel.
Ava turned pale. "They found us."
Above, the Archive's hull cracked.
Echo One had followed.
