Larva erupts from ventilation shafts

Lycett stumbles onto the first physical evidence of the Wirrn’s infiltration—a ventilation grille battered inward, its edges glistening with virulent green residue. As he traces the trail into the chamber, Rogin’s shout snaps his attention toward a horrific eruption; a parasitic larva bursts from the shaft directly behind Lycett, propelling him into desperate flight toward an empty cryopod. The assault exposes the station’s fragility, scattering the crew’s fragile cohesion and shifting the struggle from uncertainty to open, violent conflict as the Wirrn’s swift advance cripples their already tenuous foothold on Nerva. key_dialogue: [ LYCETT: Over here.

Who Was There

Characters present in this moment

4
Lycett
primary

Panicked but methodical, shifting rapidly from curiosity to terror as survival overrides all other considerations

Crouched low as he crab-walks beside the ventilation grille tracing the green residue, Lycett suddenly wheels to defend himself when Rogin’s urgent call redirects his attention. He lurches into the nearest open cryopod, slamming its lid behind him as the larva skitters past his fleeing form, its slick body glistening under the chamber’s sickly amber lights.

Goals in this moment
  • Investigate the source of the green trail and ventilation damage
  • Seek immediate shelter from the erupting larva
Active beliefs
  • Believes the station must be secured against the invaders before revival protocols resume
  • Believes personal concealment offers the only viable survival strategy in the moment
Character traits
Pragmatic urgency overriding initial hesitation Instinctive self-preservation overriding procedural caution Physical agility in desperate maneuvering
Follow Lycett's journey
Rogin
primary

Terrified yet compelled to act, snapping out of fatalistic resignation when collision with danger becomes unavoidable

Already moving to alert Lycett as he spots the larva bursting toward him, Rogin’s voice cracks with urgency. He abandons calm technical detachment to shout repeated warnings and evacuation orders, his dark humor evaporating under the visceral sight of the larva’s emergence that forces him into protective action despite his underlying fatalism.

Goals in this moment
  • Warn Lycett of immediate danger behind him
  • Ensure evacuation from the chamber at all costs
Active beliefs
  • Believes that clear, immediate warning could prevent tragedy
  • Believes that evacuation remains the only viable defense against the Wirrn
Character traits
Cynical restraint giving way to primal protective instinct Exhibition of vocal authority during crisis Rapid adjustment from detached observer to active responder
Follow Rogin's journey

Hostile, driven purely by predatory instinct and biological imperative

Bursting through the ventilation shaft with oily neon slime trailing behind, the Wirrn larva surges upward with viscous speed. Its translucent body pulses with internal organs visible as it orients toward Lycett’s fleeing form, exhibiting ruthless efficiency in pursuit despite the fragility of its gelatinous tissue.

Goals in this moment
  • Locate and consume organic matter to support Wirrn reproduction
  • Eliminate immediate threat posed by crew members
Active beliefs
  • Believes that prey within reach must be attacked without hesitation
  • Believes that infiltration of the station’s most vulnerable points will yield plentiful nourishment
Character traits
Extreme physical adaptability and speed Ruthless single-mindedness in targeting prey Tactical aggression despite apparent structural fragility

Confused but galvanized into action by the need to understand the crisis and assert medical authority

Standing amidst the pods as the chamber’s alarms shriek, Harry’s clinical detachment fractures under Rogin’s chaotic call. He seeks rapid clarification from Rogin while absorbing the impossibility of a larva’s presence, his medical instincts already searching for any controllable threat amid the unfolding disaster.

Goals in this moment
  • Obtain immediate clarification about the unfolding crisis
  • Prepare for potential medical intervention if any crew remain vulnerable
Active beliefs
  • Believes that understanding the threat is the first step toward countering it
  • Believes that medical expertise may soon be critical in this crisis
Character traits
Clinical detachment challenged by visceral horror Immediate need to understand the situation overriding all else Pragmatic search for control points in unraveling systems

Cryo-Pod D3 Corrupted Revival Unit

Once-frozen chamber for cryogenic revival, D3’s open lid now provides Lycett with emergency shelter from the erupting larva. Its interior lights flicker erratically as the chamber’s systems falter under environmental stress, the pod’s cracked shell reflecting the chaotic amber alarms while Lycett collapses inside, slamming the lid shut behind him.

Before: Closed cryopod containing a frozen human occupant, systems maintaining cryogenic stasis
After: Suddenly repurposed as makeshift shelter, with fledgling occupant inside and disrupted lid controls
Cryogenic Chamber Vent Grille (East Wall)

Originally intact, the ventilation grille has been torn inward by immense force, its weakened frame bent to allow Wirrn entry. The green residue clinging to its edges serves as irrefutable proof of infiltration, while the battered metal becomes the entry point for the erupting larva. The grille’s failure directly enables the chamber breach.

Larval Green Residue Trail

The neon-green slime streaming from the ventilation grille forms a physical trail of contamination, marking the Wirrn’s ingress path like malicious breadcrumbs. Lycett’s gloved hand recoils from its viscous touch, the residue refusing to disperse and instead clinging stubbornly to the grille’s edges as the larva erupts directly behind his investigation.

Places and their significance in this event

1
Space Station Nerva Cryogenic Vault

The chamber functions as the epicenter of terror as emergency lights cast sickly pulsations over rows of transparent cryopods. Its ventilation systems, originally designed for sterile circulation, become conduits for Wirrn infiltration while failing alarms broadcast the collapse of human safety protocols. The metallic tang of ozone mixes with overheated machinery, amplifying the sense of containment failure.

Atmosphere Overwhelming tension with flickering emergency lighting and reverberating alarms
Function Primary battleground for survival as infiltration point meets human last refuge
Symbolism Represents humanity’s fragile foothold on survival now collapsing under alien assault
Access Open to all crew but compromised by alien breach points
Constant vibration from failing life-support systems Sickly amber glow from emergency lighting
