Doctor uncovers Nimon invasion via hyperspace

Romana spots an egg-shaped transmat capsule as the Nimon announces Skonnos as its new home. Two more adult Nimons emerge, revealing Crinoth is destroyed and Skonnos is their next target for mass migration. The Doctor explains the capsule uses black holes and a hyperspace tunnel for instant travel, making the invasion inevitable unless stopped. He deduces reversing the energy flow could send the Nimons back to their homeworld. Romana inspects the capsule before an alarm forces her quick exit, confirming the urgency of sabotaging the controls. This moment shifts the story from local infiltration to existential planetary defense as the Nimon’s full-scale plan is revealed.

Who Was There

Characters present in this moment

6

Calculated urgency laced with intellectual excitement, tempered by awareness of the devastation reversing the beam could unleash

The Doctor pivots from speculative analysis to urgent deduction upon seeing the capsule, using Romana as an extension of his intellect while guiding Seth and Teka into defensive roles. He physically examines the capsule’s components alongside Romana, confirming a potential countermeasure—reversing the hyperspace energy flow—while warning of its catastrophic risks.

Goals in this moment
  • Determine the function and vulnerability of the transmat capsule to neutralize the Nimon migration
  • Devise a plan to reverse the hyperspace tunnel’s energy flow before the Nimons fully activate their invasion corridor
Active beliefs
  • Technological vulnerabilities exist in even the most advanced systems if understood correctly
  • Sacrificing a controlled planetary blast may be the only way to prevent total conquest by the Nimons
Character traits
Analytical Resourceful Risk-taking Pedagogical

Focused intensity with underlying urgency, quickly transitioning from observation to hands-on intervention

Romana spots and identifies the transmat pad and capsule before the Doctor explains its mechanics, then immediately seizes a sonic screwdriver to physically inspect the device. Her rapid diagnostic halts only when an alarm forces her withdrawal, confirming the desperate timing and operational instability of the stolen technology.

Goals in this moment
  • Assess the capsule’s operational status and sabotage points to disrupt the Nimon migration
  • Confirm the Doctor’s theory on hyperspace mechanics and validate the potential for reverse-flow reversal

Nimon
primary

Relentless determination combined with the gleeful arrogance of a conqueror unveiling a masterpiece of exploitation

The Nimon activates the main lever to open the hidden transmat panel and unseals the egg-shaped capsule, reveling it as the heart of the invasion technology. With two more Nimons at its side, it announces Skonnos as the new homeworld and commands the commencement of mass migration, turning a ritual chamber into a staging ground for galactic conquest.

Goals in this moment
  • Confirm the destruction of Crinoth and consolidate Skonnos as the next staging point for Nimon expansion
  • Initiate immediate mass migration by activating the hyperspace tunnel through the capsule’s energy beam
Active beliefs
  • Total subjugation through technological terror ensures undying loyalty from subject races
  • The brutal logic of migratory conquest is morally neutral—only the strong survive across space

Cold confidence bordering on complacency, treating destruction and migration as routine operational updates

Nimon 2 arrives in tandem with another adult Nimon and immediately broadcasts the success of the Crinoth campaign and the inevitability of Skonnos as the next operational target. Its confident urgency reinforces the primary Nimon’s authority and underscores the scale of the impending invasion—thousands or millions will follow within hours.

Goals in this moment
  • Verify the operational readiness of the Skonnos migration corridor and confirm the Nimons’ foothold
  • Demand immediate progression to full-scale migration to capitalize on the momentum from Crinoth’s fall
Active beliefs
  • The Nimon race’s survival depends on ceaseless expansion regardless of cost in lives
  • Skonnos’ compliance and resources make it the optimal next step in their conquest

Conflicted denial masking a deeper helplessness, resenting the necessity of relying on outsiders to save his people

Seth reacts with ignorance and inertia when the crisis escalates, unable to comprehend the hyperspace migration plan revealed by the Nimons. He defers to the Doctor’s authority, following orders to stand guard despite his confusion, embodying the helplessness of a leader who once bargained with powers beyond his control.

Goals in this moment
  • Execute the Doctor’s commands to protect the capsule as a symbolic act of leadership
  • Survive the encounter to lead his people once the immediate danger passes
Active beliefs
  • His title as Prince obligates him to obey those who promise salvation—even if it means ceding control
  • The Skonnos regime’s reliance on external forces has made Skonnos existentially vulnerable

Teka
secondary

Overwhelmed shock slowly crystallizing into horrified understanding as the scale of the Nimons’ plan becomes clear

Teka stands frozen with fear and confusion as the Nimons arrive and their migration plan is announced. Her comprehension lags behind Seth’s and the Doctor’s rapid understanding, but she listens to Romana’s explanation about the technology’s reach—propelling her from bewilderment into confrontation with the grim reality of interstellar conquest.

Goals in this moment
  • Comprehend the immediate threat to Skonnos so she can act in defense of its people
  • Absorb enough technical detail to trust Romana and the Doctor’s proposed plan despite her terror
Active beliefs
  • The technology enabling instant travel across stars implies a war that cannot be won by conventional means
  • Rebellion may require weapons beyond physical force—intellectual and technological coups

After: Returned temporarily to the Doctor when Romana is forced to flee the chamber due to the alarm
Empress Passenger Corridor Alarm System

The alarm system erupts as a metallic klaxon warning of structural exposure, forcing Romana to abandon her sabotage attempt mid-operation. The blaring siren cuts through the Nimon’s lab, signaling the escalating exposure risk and accelerating the timeline for the Doctor’s plan.

After: Blaring continuously, signaling the immediate need for evacuation or tactical adjustment
Skonnos Artificial Black Hole

The black hole serves as the counterweight anchor to the hyperspace tunnel, providing the spatial distortion required for near-instantaneous travel. The Doctor explains that the capsule funnels energy through the twin black holes—one at journey’s start and one at end—forming the trans-dimensional corridor the Nimons plan to flood with millions of their kin.

After: Stable enough for the Doctor to theorize its collapse via reversed energy flow, but unaltered prior to Romana’s interruption
Hyperspace Tunnel Energy Beam

The energy beam pulses from the capsule’s core, warping local spacetime into the hyperspatial tunnel that will allow millions of Nimons to stream from Crinoth to Skonnos within moments of activation. Its visible shimmer and audible hum dominate the lab’s sensory field as Romana reaches toward it before the klaxon cuts short any further contact.

Before: Likely dormant until the lever triggered the capsule’s …
