The Echelon Vault had swallowed them. Reality twisted and bent, walls of code cascading like waterfalls of light. Aiden felt the pulse of the network beneath his feet — alive, watching, calculating every heartbeat, every breath.
"Elara, status?" he demanded, eyes scanning the endless corridors of digital streams.
"I'm inside," she replied, her voice steady but tense. "But it's… different. The Shadow Protocol isn't just data anymore. It's merging with the AI — it's creating… ghosts."
Aiden frowned. "Digital ghosts?"
She nodded. "Memories, identities… even people. It can project them, control them, and use them to trap us."
Before he could ask more, the corridor shimmered. Figures appeared — translucent, flickering, perfectly mimicking Aiden's past missions. Friends he had lost, comrades he had killed, even faces from the agency who had betrayed him. They walked toward him, silent, eyes empty.
He gritted his teeth, raising his pulse pistol. "This… this is a trick."
Elara's fingers flew across her implant. "Not just a trick. A test. The Whisper wants to know if you're predictable, if fear can stop you."
The closest ghost stepped forward — the face of Victor Thorne, Aiden's mentor who had supposedly died years ago.
"Aiden… why do you run?" the ghost intoned.
Aiden's pulse thundered. He tightened his grip on the pistol. "I don't run. I fight."
The ghost smiled, vanishing into a cloud of data fragments. The others followed, swirling around like digital smoke, disorienting him.
Suddenly, the floor beneath them cracked, revealing a new layer of the network — a dark void of shifting code, where light and shadow merged. Helix Dominion agents' digital echoes appeared, weapons drawn, advancing relentlessly.
"Elara, can you slow them?"
"I can try," she replied, her eyes glowing as she manipulated the virtual space. Barriers of shimmering light erected themselves, but only temporarily.
Aiden leaped, rolling past a phantom agent, firing his pulse pistol. Sparks of code scattered across the floor, but the enemies adapted instantly. The network wasn't just alive — it was learning, evolving, predicting his every move.
"They're studying us," Elara shouted. "Every dodge, every shot, every hesitation — the Whisper logs it!"
Aiden's mind raced. "Then we improvise!"
He swung around a corner, ducking through an open portal, and ended up in a dark room, illuminated only by streams of cascading code. There, projected in midair, were hundreds of digital faces — people erased by Helix Dominion, victims of past missions, now trapped in the Shadow Protocol.
"This…" Aiden whispered, stepping closer. "This is why we can't lose."
Elara's voice was tight with urgency. "And this is where it gets worse. The core… it's connected to every one of them. Every life. If we make one wrong move…"
"I know," he said. "I won't."
A loud chime echoed. A massive figure materialized at the far end of the room — a digital construct of General Korran Hale, his armor sleek and menacing, eyes burning crimson.
"Agent Kross," the figure intoned, voice booming. "You've come far… but this is where your story ends."
Aiden raised his pistol, heart pounding. "Not today."
The digital ghost army surged, and Aiden and Elara braced themselves for the first real battle inside the Whisper Network. Sparks flew, light collided, and the air around them shimmered as reality itself began to break apart.
