The Return – Assumption of Command – Star Trek Fanfiction (Red Directive #49)

We had made it.

“Helm,” I said, my voice even, measured. “Reduce speed to impulse. Maintain approach vector to Deep Space Nine.”

“Aye, captain,” Ensign Jaxa replied, hands steady over the controls. “Impulse engaged.”

The station remained in view on the main viewscreen—small at first, then growing as we closed distance.

Deep Space Nine.

Unchanged.
Stable.
Home.

For me, it had been for six months before we departed for EOS Prospera.

Only one month had passed since our departure.

No communications with Starfleet for nearly that entire duration.

It is… not difficult to extrapolate that Starfleet’s response will likely be unfavorable.

I remained seated.

Posture precise. Hands resting lightly on the armrests of the command chair.

Unmoving.

Behind me—

“Doctor,” Commander Darak said quietly.

The Emergency Medical Hologram stepped forward from the turbolift, his expression already set with unmistakable irritation.

“I believe I made my orders explicitly clear, Commander,” the EMH said sharply. “The patient was to remain in Sickbay under my supervision.”

His gaze shifted directly to me.

“And yet, here we are.”

I did not turn.

“I assessed the situation,” I replied. “Your directive conflicted with the operational requirements of the vessel.”

“My directive,” the EMH said, stepping closer, “was issued to preserve your neurological stability. You were not fit for duty.”

“Incorrect.”

That earned a pause.

I rose slowly from the command chair and turned to face him.

“My condition was within tolerable parameters,” I continued. “The ship required command continuity during a critical navigational event. I provided it.”

“You ignored medical authority,” the EMH snapped. “That is not a matter of interpretation.”

“It is,” I replied calmly, “when weighed against mission survival.”

A brief silence.

Tension—sharp, contained.

The EMH straightened.

“I will be filing a formal report with Starfleet Medical,” he said. “Your actions constitute a direct violation of medical override protocol.”

I inclined my head slightly.

“Noted.”

There was no resistance.
No argument.
Only acknowledgment.

That… appeared to unsettle him further.

“See that you do,” Commander Darak added quietly from behind.

The EMH turned sharply toward him. “Oh, I intend to.”

I turned back toward the viewscreen, ignoring Commander Darak’s unexpected deviation from prior conduct.

“Helm, bring us to station-keeping position,” I ordered.

“Aye, captain.”

“Drim, open a channel to Deep Space Nine Operations.”

“Aye, captain.”

Drim moved across his console. A tone sounded.

“Channel open, captain.”

I stood from the command chair and took one step forward.

“Deep Space Nine, this is the USS Cairo requesting permission to dock.”

A brief pause.

“USS Cairo, this is Major Kira Nerys. Permission granted. Proceed to docking port six.”

Major Kira’s voice carried clearly across the bridge.

Measured.
Controlled.

I allowed the smallest shift in breath.

“Acknowledged, Deep Space Nine.”

I turned slightly.

“Helm, take us in.”

I resumed my seat as Ensign Jaxa guided the ship toward the docking pylons.

The docking sequence was precise.
Calculated.
Executed without error.

Magnetic clamps engaged with a muted, resonant impact that carried through the hull.

The Cairo… was home.

“Docking complete,” Ensign Jaxa confirmed.

I stood.

“Commander Darak, you have the bridge.”

A fraction of a second.

He met my gaze.

“Yes, captain.”

No further exchange.

I turned and moved toward the turbolift.

“Captain,” the EMH called after me.

I paused—but did not turn.

“I will be submitting that report.”

“I would expect nothing less, Doctor.”

Then I stepped inside.

“Primary airlock.”

The doors hissed closed and the lift began its descent.

Multiple lines of analysis presented themselves simultaneously.

I had clearly caused distress to Commander Darak, but the time I had spent in Sickbay had allowed for sufficient evaluation of our situation.

I was reminded that I had been promised to another Vulcan at a young age, as part of established Vulcan tradition.

To break that bond would bring dishonor to my family.

As a descendant of the lineage of Sarek, such an outcome was not desirable.

I clenched my fists as the thought persisted.

I had not seen my betrothed in decades, yet I was expected to uphold this tradition… even as my focus had shifted elsewhere.

The turbolift reached its destination.

The doors opened.

I suppressed the intrusive line of thought.

Then stepped into the corridor, where lower decks personnel were already unloading cargo and coordinating docking procedures.

My attention shifted to the anticipated debrief with Commander Sisko.

Even in the absence of obligation, it is highly improbable that Commander Darak and I would be reassigned together… assuming we are not decommissioned first.

I adjusted my posture.

My focus was not fully aligned with the primary matter.

Before I became aware of it, I was standing at the primary airlock.

I accessed the panel.

The hatch opened.

I stepped inside.

A sharp hiss filled the chamber as the pressurization cycle initiated.

I remained still.

Composed.

Meditating to suppress further distraction.

The cycle completed.

The hatch released.

I stepped into the outer corridor of the habitat ring.

Constable Odo was already waiting.

“Back so soon, Commander?”

I did not correct him.

“There were complications with our mission.”

He glanced toward the Cairo through the viewport.

“I see that. I’m sure Commander Sisko can’t wait to hear about it.”

His gaze shifted past me—toward the empty airlock.

“Where is Captain Kelly?”

A brief hesitation.

“Her status will be included in my report to Commander Sisko.”

Odo studied me.

Then the ship.

Then me again.

“Uh huh.”

He stepped aside, gesturing forward.

“Commander Sisko is in Ops. He was expecting Captain Kelly when he heard the Cairo had docked. I’m sure you will suffice for the moment.”

He shook his head as he turned for the airlock.  

“I have security sweeps to run. Let’s see what you’ve brought back with you.”

I inclined my head and proceeded toward Ops.

The duration of the walk did not exceed several minutes.

I paused at the entrance.

This is not a conversation I would have chosen… but it is necessary.

I steadied my posture and entered.

Operations was unchanged.

The low hum of systems.
The steady movement of officers.
Order.
Structure.
Familiar.

Commander Benjamin Sisko stood near the central operations table.

Waiting.

Observing.

I approached and stopped at an appropriate distance.

“Commander.”

“Commander,” Sisko replied evenly.

A brief glance.

Assessing.

“You’ve had an eventful return.”

“That is an accurate assessment.”

He gestured.

“Walk with me.”

I followed him into his office.

He allowed me to enter first.

I took the seat across from his desk.

He sat opposite me, hands folding together.

“I expected Captain Kelly. Where is she?”

“Captain Kelly is no longer aboard the Cairo. She is presumed deceased following the destruction of EOS Prospera. Recovery was not possible.

The android Aura was also lost. Her systems were integrated into the structure prior to its destruction.”

“Destruction of EOS Prospera?”

His tone sharpened immediately.

“Captain… now, I presume?”

A short pause. 

“That installation was designated for Federation colonization.”

He leaned forward with intensity.

“Where are those colonists?”

“The Federation colonists were successfully established on EOS Prospera.”

His expression tightened.

“Following colonization, the structure demonstrated adaptive intelligence and initiated direct integration with the population.”

He started to study me as I spoke. 

“By the time we identified the process, the colonists were no longer present as independent entities.”

“Integrated…”

He leaned back, fingertips pressed together.

“That’s not possible.”

“The last transmission received from Starfleet included records from the Federation refit of the station. Analysis of that data identified the original creators as an ancient species designated the Elionvorel.”

He frowned.

“Starfleet believed them extinct.”

“Yes.”

I held his gaze.

“The extinction appears to be directly attributable to the system they created.”

He stood abruptly.

“Get to the point, Captain.”

“The Elionvorel’s technology exceeded all known Federation parameters. The station was operating far beyond expected limits. That is why Captain Kelly requested those records.”

He sat back again, watching carefully.

“In that datastream, there were also records of the Federation refit crew. The synthetics never made it back, and all eight humanoids experienced systemic failure within six to eight months following their departure from the station.”

I shifted position with unease. “Receiving that data prompted the crew to run numerous analyses and diagnostics of the station in an attempt to determine why it was operating beyond normal parameters. Our mission was to ensure the colonists could safely inhabit that station long after our departure.”

Commander Sisko appeared annoyed. “Like I said, Captain, get to the point!”

“We discovered that the Elionvorel had been integrated into their own station. That is why they are extinct. The station had become... fully sentient.”

He jerked back and let out a small laugh. “A station… fully sentient. How would Starfleet miss that?”

“Like I said, Commander, their technology was far more advanced than anything we had ever encountered. When the Federation refit crew arrived, the station correctly perceived their presence as preparation for a larger arrival.”

I paused. “It was able to remove their cognitive anchors without detection by Starfleet. That is how they survived for so long after their departure. Systemic failure did not occur until the station required access to those cognitive anchors.”

Sarcastically, he responded, “And what does this have to do with the colonists?”

Humans had minimal tolerance for incomplete analysis. How one expects a comprehensive explanation of such events within limited time constraints remains… unclear.

“The station required those cognitive anchors to prepare for the Cairo’s arrival.”

I paused.

“To prepare itself to fully integrate the entire colonist population… including their physical forms.”

He let out that same laugh. “Their bodies? And you determined that from your analysis?”

“We did not rely solely on Starfleet records regarding the Elionvorel. We encountered them… within the station.”

He shook his head, one eye closing slightly, the other narrowing at me with increased suspicion. “With this analysis of yours, you determined the entire colonist population would have been integrated into the station in the same manner as the Elionvorel.”

He paused and met my gaze with direct precision.

“Then tell me… how are you here?”
