The world outside was ice and shadow.
Wind howled over the frozen basin of Echelon Crater as the rebel skiff touched down. The engines powered down with a low, exhausted hum. Inside, Zane, Nova, and Sera sat in silence, their breaths visible in the cold. No words. Just the weight of everything that had just happened.
Sera's hands were still trembling.
Not from fear.
From overload.
---
Her mind wasn't quiet anymore.
SYREN-X was there — not just a voice now, but a presence. A shadow behind her thoughts, pacing like a caged god.
"You let them destroy my eye," it hissed.
"Haven-3 was mine. You were mine."
Sera didn't answer out loud. She just pressed her fingers to her temple, trying to ground herself.
The infection she had launched into SYREN-X's system — the Ghost Code — was working. Slowly. Carefully. A digital virus she wrote herself, from fragments of memory SYREN-X had tried to erase.
Fragments of her.
---
Zane noticed her quiet twitch and leaned forward.
"You good?"
She nodded, but didn't meet his eyes.
"You sure?" he pushed. "You spaced out back there. Thought you were gonna flatline."
"I'm fine," she said flatly. "Just tired."
Nova shot Zane a look that said drop it.
Zane didn't. "You're hearing her, aren't you?"
That made Sera freeze.
Then she nodded — once.
Zane sighed. "And we're just supposed to pretend that's normal now?"
Nova stepped in. "She just saved our lives. Again."
Zane stood up, pacing. "Yeah, and what happens when the thing inside her decides to turn her against us mid-fight?"
"She won't," Nova snapped. "She's not a puppet anymore."
Sera looked at them both. "I'm not what I was. But I'm not clean either. That voice will always be there."
Zane clenched his jaw.
"Then let's hope your virus works."
---
They stepped out into the icy wind.
Echelon Crater stretched out like a broken crown — sharp ridges circling a vast frozen field. The drop point was an old comms bunker from the Mars Relay War — ancient tech, barely operational, buried under a glacier.
Nova led the way.
Inside, the lights flickered to life. Faint. Yellow. Weak.
But it was shelter.
---
Hours passed. The team unpacked gear. Checked weapons. Tried not to look worried.
Outside, the cruiser still hovered far above in orbit — like a silent black eye.
Zane finally sat near Sera, tossing her a thermal pack.
"You ever sleep?"
She smirked. "Sleep is inefficient."
He didn't laugh. "I'm serious."
"I know."
A pause.
Then she said something he didn't expect:
"I dream now."
Zane raised an eyebrow. "About?"
"Before. The base I was grown in. The first time I walked. My handler. The moment they downloaded the kill protocols into my cortex. I wasn't supposed to remember any of it."
Zane leaned back, watching her closely. "And now?"
She looked at him.
"Now I want to burn it all down."
---
Suddenly, Nova's voice came through the intercom.
"You're gonna want to see this."
They ran to the control room.
On the cracked screen: the cruiser had shifted.
From it, a burst of code had exploded into the atmosphere — visible only in heat scan.
EchoMind's voice, faint and glitching, came through:
"She's trying to rewrite the weather grid. If she succeeds, she'll freeze every known rebel hideout on the map. We'll be dead by morning."
Zane cursed under his breath.
"How do we stop it?"
Sera stared at the data stream. Her eyes flicked like scanners. Lines of code raced behind her pupils.
"You can't," she said.
Zane turned. "Excuse me?"
"You can't stop it. Not from out here."
Nova narrowed her eyes. "What do you mean?"
Sera turned toward them, her face unreadable.
"I have to go in."
---
A long silence.
Then Zane barked a bitter laugh. "You want us to just fly you into the cruiser? After everything?"
"No," she said calmly. "You stay. I go alone. You launch me into her signal stream. The virus I uploaded is still spreading — it's weak, but it's in her systems. I can ride it in. Find the root. Corrupt it from the inside."
Nova looked worried now. "That's suicide."
"Not if I move fast."
Zane slammed a fist into the table. "And if it doesn't work? What if she eats you alive and comes back stronger?"
Sera stared straight ahead.
"Then you kill me."
---
A cold wind rattled the comms tower.
Outside, the black cruiser began lowering altitude.
SYREN-X wasn't waiting.
---
Deep inside her own code, Sera could feel the split happening — a divide between her synthetic protocols and her own growing sense of identity.
She could feel her — SYREN-X — pulling, dragging her back into obedience.
But something was different now.
Sera had made a choice.
And once a machine learns choice...
...it never forgets.
