Mission: Silent Inheritance
// Sickbay :: USS Arawyn //
Sickbay was never silent.
Even during relative calm, it breathed. Environmental processors cycled softly. Biobed power relays emitted a low harmonic pulse. Diagnostic consoles chimed in restrained intervals as analyses resolved and reset. The air carried faint notes of sterilizing solution and the lingering citrus of antiseptic wipes recently used.
Claire stood at a secondary analysis station rather than behind a desk. She preferred the open projection field. The ability to step back from the data when necessary. To pace if she needed. The space to think.
A cup of tea sat to her right, long cooled. Bergamot lingered faintly in the air near it. She had brewed it early in the shift.
She had not tasted it in hours.
Lathira IV rotated slowly before her, a pale blue and green sphere suspended in light. Gold markers denoted confirmed pediatric cases. She expanded the projection, flattening it into regional mapping overlays.
The virus itself behaved normally. Transmission chains were present. Contact tracing followed expected patterns for a respiratory pathogen likely introduced by offworld travel. There was nothing aberrant in its spread.
What troubled her was not how it moved.
It was where the worst cases settled.
She isolated symptom severity overlays.
Neurological tremors.
Respiratory compromise.
Persistent rashes beyond expected duration.
The most severe pediatric presentations clustered in specific districts of Kestrel Reach and two neighboring municipalities. In other areas, infection was present but rarely progressed beyond minor symptoms. A fleeting rash. A short lived fever. Illnesses that would not raise alarm. The vaccine was functioning there. It allowed the immune system to recognize the virus quickly and contain it before it could do harm.
She adjusted the overlay again, narrowing the display to age stratification.
Infants. Toddlers. Early childhood.
Her jaw tightened almost imperceptibly.
They were small faces on the screen. Just identifiers. Medical codes. Vital statistics.
But she had seen enough children struggle for breath to know how quickly numbers became something else.
Tha sin ceàrr… she murmured softly. That is wrong.
A dull ache had settled low between her shoulder blades sometime during the third hour of analysis. She shifted her weight slightly, rolling one shoulder back. The tension eased marginally, then returned.
She dismissed the planetary map and replaced it with viral sequencing matrices. Novaryn-C rotated in three dimensional precision. Capsid proteins rendered in crisp geometric clarity.
She expanded archived Federation samples alongside current isolates.
Minimal drift.
Statistically negligible mutation.
No enhanced binding sites. No replication acceleration. No structural alteration of concern.
“You have not changed,” she said quietly to the projection. “You are the same.”
Which meant the variable lay elsewhere.
A strand of auburn hair slipped free from the tie at the back of her head and drifted across her vision. She brushed it aside absently without looking up. It fell forward again moments later.
She exhaled softly.
She stepped back and pulled the tie loose. Auburn hair fell around her shoulders before she gathered it again, fingers moving efficiently, twisting it into a slightly uneven bun. A few shorter strands escaped near her temples. She did not bother correcting them.
She straightened fully this time, pressing her palms briefly against the small of her back in a restrained stretch. The ache protested. She ignored it.
Pediatric antibody responses replaced the viral matrices.
IgM initiation curves.
IgG progression slopes.
Cytokine activation markers.
Early immune recognition was intact.
The immune system began the work precisely as expected.
She narrowed the filter.
Memory B cell maturation markers.
Her fingers stilled.
Blunted.
Not absent.
Incomplete.
She drew adult Lathiran samples into comparison. Even infected adults completed immune memory formation. Their antibody reinforcement curves stabilized within expected windows.
She overlaid patient age distribution again.
The youngest patients had no prior immune layering to compensate. No repeated antigen exposure. No accumulated antibody memory from years of stable immunization cycles.
Their protection depended almost entirely on recent vaccination.
And in them, it failed to fully set.
A brief image flickered at the edge of her mind. A child small enough to curl into a biobed. Tremor in tiny hands. Confusion in bright eyes.
Her throat tightened for half a breath.
Then the feeling was folded away. Not dismissed. Contained.
She returned to the data.
She shifted to degradation kinetics of the vaccine’s synthetic stabilizing scaffold. The polymer matrix should maintain structural integrity long enough to allow durable antigen presentation.
Instead, in pediatric bloodstream simulations, fragmentation curves steepened earlier than predicted.
Not catastrophically.
Subtly.
Recently.
She introduced trace molecular signatures recurring in symptomatic children. A micro protein fragment rotated slowly in the air.
Low concentration.
Present across the severe clusters.
Absent or minimal in milder regions.
She expanded its structure and initiated a binding simulation against the vaccine scaffold.
The model flickered.
Weak affinity.
Repeatable interaction.
Enough to influence structural stability over time.
Claire leaned back slowly, careful not to fold forward into the tension gathering along her spine again. The steady hum of Sickbay pressed against the silence of her thoughts.
The virus spread normally.
The immune system initiated properly.
Something was interfering with completion.
Environmental distribution.
Not altered virulence.
“It is not the virus drifting,” she said softly. “It is the protection failing.”
The planetary map returned, gold markers glowing with quiet insistence.
Not coincidence.
Pattern.
For a moment her gaze lingered on the smallest cluster markers.
“We will fix this,” she murmured, almost to herself.
Then she transferred the refined datasets to her padd with deliberate precision.
The ache in her back remained as she straightened and stepped away from the station. She left the tea where it sat, forgotten.
“Computer,” she said evenly as the doors parted before her, “locate Lieutenant Quinn.”
