The wind howled through the narrow metallic corridors of the underground arcology, its cry muffled by the shielding plates bolted to the walls. Kael walked ahead, the Echo still humming faintly in his mind like a half-remembered melody. The mark on his arm shimmered under the pale light—more vibrant, more alive—twisting with strange runes that sometimes pulsed in reaction to his thoughts. He had passed the Protocol. But the war had only just begun.
Syra walked beside him, silent for a long time. Her eyes scanned every crevice, every shadow. She no longer wore the sarcastic smirk she used as a mask. Something had changed in her too—her presence more grounded, less elusive. She had walked the Echo alongside him. She had seen what he saw.
"We need to find the others," she finally said, voice barely above a whisper.
Kael nodded. "Jax and Bren. Where did we last lose contact?"
Syra turned and tapped her bracer, projecting a flickering map in the air. Red pulses glowed near a collapsed sector of the arcology—Sector D-17. The Resistance had once used it as a forward base before the Wielders breached it.
"They fell back after the skirmish at the Spire Bridge," she said. "No one's heard from them since."
Kael's gaze darkened. "We're going in."

Sector D-17 was a graveyard.
Collapsed towers jutted from the ground like rusting bones. The air buzzed with static interference, thick with the scent of scorched circuitry and chemical dust. Drones buzzed overhead, their crimson eyes scanning for movement.
Kael and Syra moved in silence, cloaked in adaptive shields. They ducked behind debris, passed through motionless husks of old war machines, until they reached the edge of a shattered plaza.
That's when they heard it—a pulse of sound. Familiar.
A coded Echo.
Kael tapped his fate-mark against the broken wall, humming in resonance. The wall shimmered, revealing a hidden hatch. He looked at Syra. She nodded.
Inside was a narrow crawlspace, descending into an auxiliary chamber. And in its center—
"Jax," Kael breathed.
The young man stood at a console, his signature flame-glyphs flickering faintly on his gloves. His spiked hair was messy, his jacket torn, but his eyes burned with that same wild spark.
"Bout time," Jax muttered, grinning. "Was beginning to think I'd have to fight off an Echo Wyrm solo."
Behind him, leaning against a half-functional med-pod, was Bren—tall, calm, and calculating as ever. He was typing into a datapad, rerouting power from a damaged core.
"Syra. Kael." Bren's voice was cool. "I hope you brought more than just dramatic timing."
Kael stepped forward and extended his arm. "We brought a weapon fate won't see coming."
Jax's eyes widened at the new spiral of runes. "You passed it?"
"Yeah," Kael said. "And we're not done yet."

The four sat in the chamber, piecing together their scattered intel. Syra projected the Echo Map—the dynamic weave of shifting fate paths. Bren analyzed the divergences while Jax prepped incendiary runes.
"Look at this thread," Bren said, pointing to a glowing fracture in the weave. "It branches the moment the Shard Engine is destroyed."
"The Wielders are preparing for something," Syra said. "Something massive. They've been aligning Echo Points like coordinates."
"A ritual," Kael murmured. "To rewrite the fate-loop."
Jax snorted. "So we blow it up before they get the chance."
"It's not that simple," Bren said. "They're protected by the Warden—one of the original Fatebound. He controls the Nexus Tower."
"Then we start by taking his tower," Kael said, standing.
Syra looked at him. "With what army?"
Kael stared at his team, one by one. "We don't need an army. Just four echoes, written our way."
And the map shimmered in agreement.

That night, as they prepped for the mission, Kael stood alone at the chamber's edge. His reflection shimmered faintly on the glass floor, showing more than just his face—glimpses of the future, both glorious and grim.
Syra approached, quiet as ever. "You're afraid."
Kael didn't deny it. "I saw what I could become. In one path, I let power consume me. In another, I broke the world trying to save it."
Syra stood beside him. "You're not alone. That's the difference."
He turned to her. "What if I fail?"
She reached out and placed a hand over his fate-mark. "Then we'll fall together. And rise together. That's the promise."
Kael looked at her, at the glyphs intertwining on their skin.
"Let's write a different ending," he said.
And in the Echo, a new thread began to form.
