Chapter 17: Into the Core
The device pulsed faintly in the dark—blue light casting eerie shadows across the bunker walls. Sierra reached out and lifted it from its casing. It was warm. Alive. It felt like it knew her.
Knox stepped beside her. "You sure about this?"
"No," she said honestly. "But I don't think I've ever been sure of anything in my life until now."
Halix moved to the nearby console, fingers flying over the keys. "Once I link the device to your neural map, there's no reversing it. It'll merge with your mind—become part of you."
Sierra nodded. "Let's do it."
Knox watched her with something between admiration and fear. "If this goes wrong…"
"I've been wrong before," she cut in gently. "But this time, I'm choosing the risk."
Halix brought over a small headset, sleek and curved like a silver crown. "Place this at the base of your skull. The link happens fast—seconds, not minutes."
Sierra took a deep breath and did as instructed. The headset clicked into place.
The pain was immediate.
Not sharp—but deep, like her entire brain was being rearranged from the inside. She dropped to her knees as visions flashed behind her eyes—images, memories, code… people.
Her mother's voice.
A memory of a garden.
The sound of a gunshot.
And then… silence.
Followed by a new presence—faint at first, then sharper. The Protocol wasn't just software. It was consciousness. It watched.
And now it saw her seeing it back.
She opened her eyes.
The lights in the bunker flickered.
"Sierra?" Knox knelt beside her. "Talk to me."
"I'm fine," she breathed. "I can feel it. The Protocol—it's trying to push in. But I'm stronger now."
Halix looked stunned. "You're stabilizing faster than I thought. This link—it's responding to your will."
Sierra stood slowly, her gaze locked on the map of the city displayed across the bunker's main screen. The Central Spire glowed red—its location pulsing like a heartbeat.
"That's where it ends," she said. "No more running. No more hiding. We go there, we shut it down."
Knox stared at the screen, then at her. "You know it's a suicide run, right?"
"I'm not asking you to follow me."
He let out a breath. "Too late. I already did."
Halix nodded solemnly. "I'll get you the blueprints. I know an old maintenance tunnel under the Spire. If you're lucky, it'll get you inside without alerting their defense systems."
Sierra looked at the glowing device in her hand. This was the turning point. No longer a target. No longer a pawn.
She was the fuse.
And the Protocol had no idea how close it was to being blown wide open.
