Who Was There

Characters present in this moment

4

Frustrated and tense, with an undercurrent of creeping dread. Duggan’s urgency masks a deeper unease—he senses something is wrong, but his training compels him to fix the problem first and ask questions later. His emotional state is a mix of professional irritation and subconscious foreboding, as if he intuitively grasps that this sabotage is not an isolated incident.

Duggan stands in the Power Room, his hands gripping a defective Bernalium rod as he examines it under the harsh fluorescent lighting. His expression tightens with frustration as he peels back the plastic coating, revealing the sabotage. He barks orders at Chang, his voice sharp with urgency, but his focus remains locked on the rods—symbols of the station’s fragility. His technical precision contrasts with the growing chaos around him, as he prioritizes immediate solutions over deeper investigation.

Goals in this moment
  • Restore the Bernalium rods to functional status as quickly as possible to stabilize the Wheel’s power systems.
  • Maintain operational efficiency in the Power Room, even if it means overlooking the source of the sabotage for the moment.
Active beliefs
  • The immediate threat is the malfunctioning rods, not the *why* behind their failure (yet).
  • The crew can still outmaneuver whatever is causing these issues if they act swiftly and decisively.
Character traits
Technically astute Impatient under pressure Authoritative in crises Distrustful of anomalies (but reactive, not proactive) Pragmatic to a fault

Urgent but not panicked, with a subtle undercurrent of unease. Chang’s emotional state is one of focused compliance—he trusts Duggan’s authority and the urgency of the situation, but there’s a flicker of something unspoken in his demeanor, as if he senses that this problem is part of a larger, unresolved issue. His emotional range is limited by the station’s culture of crisis management, where questions come second to action.

Chang stands in the Power Room, listening to Duggan’s discovery of the sabotaged rods with a mix of surprise and urgency. He absorbs the information quickly, his body language shifting from passive observation to active compliance. When Duggan orders him to fetch replacements, Chang nods and moves to leave, his actions efficient but his expression betraying a hint of unease. His role in the event is reactive—he follows orders without question, but his presence underscores the crew’s desperation and the Cybermen’s success in creating chaos through seemingly mundane tasks.

Goals in this moment
  • Retrieve the replacement Bernalium rods as quickly as possible to restore the Power Room’s functionality.
  • Support Duggan’s efforts to stabilize the station’s systems, even if it means overlooking the source of the sabotage for now.
Active beliefs
  • The immediate priority is fixing the rods, not investigating why they were sabotaged.
  • Duggan’s technical expertise and authority make his orders the best course of action in this moment.
Character traits
Quick to comply with orders Observant but not suspicious (yet) Pragmatic in crises Loyal to the chain of command Slightly uneasy but not alarmed (indicating the crew’s desensitization to anomalies)

Supporting 2

Unknowingly complicit and emotionally detached (from the crew’s perspective). While Laleham herself is not present, her hypnotized state would render her emotionally flat—her actions mechanical, her demeanor uncharacteristically hollow. The crew’s obliviousness to her condition amplifies the tragedy: she is both victim and unwitting perpetrator.

Laleham is mentioned off-screen as the deliverer of the sabotaged Bernalium rods, her role in the event confined to her earlier actions. Though physically absent, her presence looms over the scene: her hypnotized state and unwitting complicity in the Cybermen’s plan are the unseen drivers of the current crisis. Duggan and Chang’s references to her and Vallance frame her as a pawn in a larger, sinister game, her competence now weaponized against the Wheel.

Goals in this moment
  • None (as she is hypnotized and acting under Cyberman control). Her 'goal' is the Cybermen’s goal: to deliver the sabotaged rods undetected.
  • Unwittingly facilitate the Cybermen’s plan to cripple the Wheel’s defenses.
Active beliefs
  • She believes she is performing her duties as usual (due to hypnosis).
  • She has no awareness of the rods’ sabotage or the Cybermen’s influence over her.
Character traits
Unknowingly complicit in sabotage Reliable under normal circumstances (but compromised here) Symbol of the crew’s vulnerability to infiltration Her actions reflect institutional trust turned against the station
Follow Laleham's journey

Emotionally hollow and mechanically compliant (due to hypnosis). Vallance’s state would be one of eerie calm, his movements precise but devoid of his usual warmth or initiative. The crew’s later discovery of his complicity would reveal the depth of the Cybermen’s infiltration, turning trust into a liability.

Vallance, like Laleham, is referenced off-screen as a co-conspirator in the delivery of the sabotaged Bernalium rods. His absence from the scene is telling: his role in the event is retrospective, his actions already completed and now exposed as part of the Cybermen’s plot. The mention of his involvement with Laleham frames him as another hypnotized pawn, his usual competence subverted into a threat. His presence in the event is spectral—haunting the Power Room through the defective rods he helped deliver.

Goals in this moment
  • None (as he is hypnotized and acting under Cyberman control). His 'goal' aligns with the Cybermen’s: to deliver the sabotaged rods without raising suspicion.
  • Unwittingly aid the Cybermen in their plan to colonize Earth by crippling the Wheel’s defenses.
Active beliefs
  • He believes he is following standard operational procedures (due to hypnosis).
  • He has no memory or awareness of the Cybermen’s influence or the true nature of the rods he delivered.
Character traits
Hypnotized and acting under Cyberman control Normally reliable and competent (but now a liability) His actions reflect the Cybermen’s ability to turn trusted crew members into weapons Symbol of the station’s eroding security

Bernalium Rods (Wheel's Power System)

The replacement Bernalium rods, though not yet physically present in the scene, are the crew’s desperate hope for stability. Duggan’s order to Chang to retrieve them frames them as a temporary solution—a bandage on a deeper wound. Their potential to restore the Power Room’s functionality is overshadowed by the unanswered question: How did the original rods become sabotaged? The replacements symbolize the crew’s reactive mindset, their focus on immediate fixes rather than addressing the root cause of the threat. Their retrieval sets the stage for the next phase of the crisis, as the Cybermen’s influence continues to spread unseen.

Before: Stored in the station’s reserves, untouched and presumably functional. Their existence is known to the crew, but their retrieval is triggered by Duggan’s discovery of the sabotage.
After: Chang is dispatched to fetch them, but their arrival is not shown in this event. Their role in the larger narrative is to buy time—time the Cybermen will use to tighten their grip on the Wheel.
Plastic-Coated Defective Bernalium Rods (Power System Sabotage)

The plastic coating on the Bernalium rods is the smoking gun of the Cybermen’s sabotage, a deceptively simple yet devastating obstacle to the Wheel’s survival. Duggan’s discovery of the plastic—its glossy, artificial sheen contrasting with the rods’ metallic surfaces—reveals the extent of the infiltration. The plastic isn’t just a physical barrier; it symbolizes the crew’s blind spots, their inability to see the enemy within. Its presence turns a routine maintenance task into a race against time, as the crew scrambles to replace the rods without understanding the true nature of the threat. The plastic coating is both a clue and an obstacle, forcing the crew to react rather than investigate.

Before: Intact and undetected, covering the Bernalium rods, allowing them to pass inspection and be delivered to the Power Room. Physically adhered to the rods, masking their true condition.
After: Peeled back and discarded by Duggan, exposing the rods’ sabotage. The plastic’s removal is a small victory, but it highlights the larger problem: the Cybermen’s ability to manipulate the crew into delivering their own downfall.
Silver Carrier Bernalium Fuel Rods (Cybermen Disguise)

The Silver Carrier Bernalium Fuel Rods are the focal point of the event, their sabotage by the Cybermen exposed when Duggan peels back the plastic coating to reveal their uselessness. These rods, delivered by the hypnotized Laleham and Vallance, are not just defective—they are a deliberate weapon in the Cybermen’s plan to cripple the Wheel’s defenses. Their physical state—covered in plastic—symbolizes the invisible threat lurking within the station, as the crew’s trust in their colleagues and systems is turned against them. The rods’ failure forces Duggan and Chang into a frantic scramble, their urgency masking the deeper infiltration already underway.

Before: Functional in appearance but internally sabotaged (plastic-coated), delivered to the Power Room by Laleham and Vallance under Cyberman hypnosis. Physically present in the Power Room, stacked among other rods, awaiting inspection.
After: Exposed as defective and useless for stabilizing the Wheel’s power systems. Duggan discards or sets them aside, and Chang is dispatched to retrieve replacements. The rods’ true role as part of the Cybermen’s infiltration is now partially revealed, though the full extent of the sabotage remains unknown to the crew.

Space Wheel W3

The Power Room is the beating heart of Space Wheel W3, and in this event, it becomes a pressure cooker of urgency and unspoken dread. The hum of machinery and the flickering consoles create a tense, almost claustrophobic atmosphere, where every second counts. Duggan’s inspection of the rods under the harsh lighting casts long shadows, mirroring the crew’s growing unease. The room’s functional role as the station’s power hub is underscored by the stakes: if the Bernalium rods fail, the Wheel’s defenses—and its survival—are at risk. Symbolically, the Power Room represents the crew’s fragile control over their fate, a control that is slipping through their fingers as the Cybermen’s sabotage takes hold.
