// USS Caelestis :: Bridge //
Warp carried them forward with steady inevitability.
Two days traveling away from Starbase 369. They were now at low warp. No fanfare. Just trajectory and analysis.
Sidra MacLaren stood at the center of the bridge, posture relaxed in appearance only. Hands loosely clasped behind her back. Eyes forward.
They had listened to the transmission until there was nothing more to extract from it.
It had not been fragmented. Not distorted by panic. Not layered in code.
It had been precise.
“This is Rear Admiral Indi Hawk. This is a message for Starfleet and more specifically Starbase 369. I, and others, are being held against our wishes. We’re at an unknown location with an unknown number of us. Please follow this message to its origin and render immediate assistance against an unknown enemy.”
That was all.
No accusation.
No speculation.
No dramatics.
Just information.
Sidra respected that.
She also understood what Indi had not said.
Unknown location.
Unknown number.
Unknown enemy.
The signal had not been strong enough to trace directly. It had ridden inside interference, shaped and masked by something environmental. Or something designed to look environmental.
They had deployed probes ahead of their warp vector. Passive. Dark. No active sweeps that would announce Starfleet interest. The probes drifted inward while the Caelestis followed at controlled velocity.
Now the stars outside the viewport elongated one final time before settling back into points of light.
“Dropping from warp,” Rucker reported.
“Bring us to low impulse,” Sidra said. “Minimal emissions.”
The deck shifted almost imperceptibly as the warp field collapsed and impulse engaged.
“Probe telemetry beginning to relay,” Operations announced.
The main viewer filled with layered sensor returns. At first glance, it was a mess of gravimetric noise and ionized particulate density. Nothing any survey vessel would waste time unraveling unless given reason.
Sidra watched without speaking as Science began peeling it back.
“Overlay density variance,” she said.
A three-dimensional model formed in stages. The interference field was not uniform. It thickened in bands, thinned in others. That alone did not make it artificial.
“Probe two indicates mass shadowing within the densest band,” Science continued. “Irregular geometry. Approximate diameter one point seven kilometers.”
The viewer shifted.
An asteroid.
Ancient rock. Scarred. Pitted. Rotating slowly within the interference pocket.
Sidra remained still.
“Natural composition?” she asked.
“Primarily silicate and nickel-iron matrix,” Science replied. Then a beat. “Admiral… surface anomaly detected along equatorial ridge.”
The image magnified.
Along one ridge line, the rock face did not follow erosion patterns. There were seams. Straight lines. Paneling integrated flush against native stone. Thermal fluctuations in precise intervals.
Not geological.
Engineered.
“Probe three confirms internal cavities inconsistent with natural fracture patterns,” Science added. “Structural reinforcement signatures present. Metallic lattice.”
Hollowed.
Not entirely. But enough.
Sidra let the silence stretch across the bridge.
Unknown location.
Unknown enemy.
Indi had been correct.
“Reactor trace?” she asked.
“Low-level but sustained energy output,” came the reply. “Shielded. Cycling at consistent intervals.”
The interference pulse spiked on cue across the display.
Every five seconds.
“Correlation?” Sidra prompted.
“Energy cycling matches field modulation.”
Something inside that asteroid was actively maintaining the surrounding distortion.
This was not a derelict.
It was inhabited.
Sidra felt the heat stir low beneath her ribs. Not anger. Calculation.
They had not identified the operators. There were no vessel signatures in the immediate vicinity. No comm traffic leaking into subspace bands. Whoever had constructed the facility understood concealment.
That alone narrowed possibilities.
But narrowed did not mean confirmed.
“Full perimeter sweep,” she ordered. “Passive only. I want confirmation there are no additional structures embedded in the debris field.”
“Aye, Admiral.”
She stepped closer to the viewer, not out of urgency but to study detail. The asteroid rotated slowly, and as it did, a faint emission port revealed itself before slipping back into shadow.
Deliberately masked.
“They did not expect to be found,” Rucker observed quietly.
Sidra’s gaze did not leave the image.
“They expected not to be traced,” she corrected.
There was a difference.
Indi’s transmission had not asked for speculation. It had asked for assistance.
Follow the message to its origin.
They had.
“Distance to outer boundary of the interference pocket?” she asked.
“Two hundred thousand kilometers.”
“Take us to the edge and hold position outside peak density.”
“Aye.”
The Caelestis adjusted course.
Sidra did not yet raise shields. Did not yet deploy active scans. Every escalation was a declaration of presence.
And presence might trigger response.
“Transporter locks?”
“Inconsistent within the densest band,” Operations reported. “Possible once we reduce interference from closer proximity.”
So.
They could not yet extract anyone.
They would have to move carefully.
Sidra turned slightly toward Science.
“Continue refining structural mapping. I want entry points, power nodes, and internal layout approximations.”
She paused.
“And keep reviewing the transmission waveform. I want confirmation there was no embedded modulation we have not yet identified.”
If Indi had hidden more within it, Sidra intended to find it.
The asteroid completed another slow rotation on the viewer.
Engineered seams glinted faintly in filtered light.
A prison carved into stone.
Or something worse.
Sidra clasped her hands behind her back once more.
“Admiral Sha’mer to the bridge.”
The call was measured, not urgent.
Sha’mer had narrowed the original bearing from her link with Indi. Now they were close enough for something else to matter.
The Caelestis eased toward the boundary of the interference field, controlled and quiet.
Unknown location.
Unknown number.
Unknown enemy.
Sidra’s jaw tightened a fraction.
“Let’s see who built you,” she said softly.
And then, “And how they intend to keep what they’ve taken.”
