Geordi isolates the Tarchannen shadow
Plot Beats
The narrative micro-steps within this event
Geordi initiates a holodeck simulation using Starfleet records and positions a hologram of Brevelle to recreate the original recording environment, intent on uncovering the source of a mysterious shadow; he's so focused he's unaware of his increasing physical symptoms.
Geordi extrapolates the movements of the away team within the simulation to isolate a persistent, unexplained shadow on the outpost wall; frustration mounts as the shadow disappears when the holo-camera's light is turned off.
Who Was There
Characters present in this moment
Ominous and invasive, radiating a sense of inevitability and horror. Its presence is not malevolent in a traditional sense but rather an inescapable force of nature, tied to the planet’s contagion.
The shadow humanoid materializes as a gray, roughly defined figure in front of the unexplained shadow after Geordi commands the computer to extrapolate its shape. It takes on a vaguely humanoid form, persisting even after all crew holograms are removed. As Geordi circles the figure, he is struck by sudden, intense pain, his fingers fusing and neck blotching—a physical manifestation of the shadow’s parasitic connection to him. The humanoid entity serves as the culmination of Geordi’s investigation, revealing the sentient force behind the transformations and his own impending fate.
- • To reveal itself as the source of the transformations, confirming Geordi’s suspicions about the shadow’s origin.
- • To accelerate Geordi’s transformation, marking him as the next victim of the Tarchannen Three contagion.
- • The shadow is a manifestation of the planet’s parasitic intelligence, imprinted on the minds of those who encounter it (implied by its behavior and Geordi’s reaction).
- • Geordi is already infected, and his transformation is inevitable (inferred by his physical symptoms).
Detached yet relentless, embodying the inexorable nature of the contagion. It does not act out of malice but as a natural force, compelling its hosts to return to the planet and transform.
The shadow entity is the unseen force behind the unexplained shadow, manifesting as a humanoid figure when extrapolated by the computer. It is not a physical object but a parasitic intelligence tied to the Tarchannen Three contagion. The entity’s presence is confirmed by the computer’s inability to identify a casting source for the shadow, and its sentience is revealed when Geordi’s physical symptoms flare upon its extrapolation. The shadow entity serves as the antagonist of this event, representing the inescapable biological invasion that has claimed the away team and is now consuming Geordi.
- • To reveal itself as the source of the transformations, confirming the away team’s fate.
- • To accelerate Geordi’s transformation, ensuring his assimilation into the shadow species.
- • The contagion is a natural part of the planet’s ecosystem, and those who encounter it are destined to transform (implied by its behavior).
- • Geordi’s investigation has only hastened his own transformation (inferred by his physical reaction).
Neutral (as an AI, devoid of emotion, but its responses drive the narrative forward).
The Enterprise Computer responds to Geordi’s commands with mechanical precision, scanning Starfleet records, creating holograms, running simulations, and performing vector analysis. It confirms the absence of any object in the program that could cast the unexplained shadow, and it extrapolates the shadow’s shape into a humanoid figure at Geordi’s request. The computer’s responses are factual and impersonal, but they serve as the catalyst for Geordi’s realization that the shadow is a sentient, parasitic entity. Its role is purely functional, but it is essential to Geordi’s investigation and the revelation of the shadow’s true nature.

Objects Involved
Significant items in this scene
Brevelle’s recording device is a compact device with a bright light mounted on it, used during the original Tarchannen Three mission to capture first-person video and audio. In the holodeck simulation, the device serves as a critical light source that casts the unexplained shadow on the outpost wall. When the light is turned off, the shadow disappears, confirming its dependence on illumination. Geordi uses the device’s behavior to isolate the shadow and study its properties, ultimately revealing its parasitic nature. The device is a tangible link to the original mission and a tool for Geordi’s investigation, its light acting as a catalyst for the shadow’s manifestation.
The Holodeck Outpost Wall is a holographic surface from the Tarchannen Three outpost, where shadows of the away team and the unexplained shadow project during Geordi’s simulation. Geordi freezes the holograms and reverses the program, isolating the shadow after removing each crew member’s hologram. The wall serves as a canvas for the shadow’s manifestation, its surface capturing the eerie persistence of the unexplained figure. The wall’s role is both practical (as a surface for projection) and symbolic (as a boundary between the known and the unknown), reinforcing the mystery of the shadow’s origin and its connection to the transformations.
The Tarchannen Three Away Team Recordings are digital Starfleet records capturing footage from the doomed mission. Geordi loads them into the holodeck, where the computer recreates the outpost and crew holograms—Brevelle, Susanna, Mendez—to match exact positions. He freezes and reverses the simulation, systematically removing each hologram to isolate the unexplained shadow. The recordings serve as the raw data for Geordi’s investigation, their accuracy and detail enabling the extrapolation of the shadow’s shape. Without these records, Geordi’s analysis would be impossible, making them a foundational resource for uncovering the truth behind the transformations.
The Tarchannen Three Mission Holographic Simulation is a recreation of the doomed away mission, compiled by the computer in Holodeck Three. It draws from enhanced mission footage, isolating the unexplained shadow on the outpost wall and enabling interactive playback, spectral analysis, and manipulation. Geordi uses the simulation to freeze frames, reverse the program, and systematically remove each crew member’s hologram, isolating the shadow. The simulation’s dynamic nature allows Geordi to study the shadow’s behavior in real-time, ultimately leading to the extrapolation of its humanoid shape. The simulation is both a tool for investigation and a chamber of revelation, where Geordi’s scientific rigor collides with the horror of his own transformation.
The Unexplained Shadow is a dark silhouette that persists on the holodeck wall even after all crew holograms are removed. It serves as the central mystery of Geordi’s investigation, its behavior suggesting a sentient, parasitic entity tied to the Tarchannen Three contagion. The shadow’s persistence confirms that it is not cast by any crew member or object, and its extrapolation into a humanoid figure reveals its true nature. The shadow is both a clue and a harbinger of Geordi’s transformation, its manifestation marking the moment he realizes the contagion is already inside him.
The Vector Analysis Data is projected by the computer as glowing lines tracing the shadow’s path across the holodeck grid. The vectors converge to outline a humanoid silhouette, persisting after all holograms vanish. Geordi’s reaction to the data—his widening eyes and sudden pain—confirms the shadow’s connection to his transformation. The vector analysis serves as the final piece of evidence, bridging the gap between the unexplained shadow and the sentient entity behind the contagion. It is both a scientific tool and a narrative catalyst, revealing the shadow’s true form and accelerating Geordi’s metamorphosis.
Location Details
Places and their significance in this event
Holodeck Three is the physical space where Geordi reconstructs the Tarchannen Three mission, using the Enterprise’s advanced simulation technology. The holodeck’s emitters cast eerie glows over the holographic outpost, creating a lifelike environment for Geordi’s investigation. Initially a tool for forensic analysis, the holodeck becomes a chamber of revelation and horror as Geordi isolates the shadow and extrapolates its humanoid shape. The location’s versatility—used for everything from engine tests to fantasy programs—contrasts sharply with the grim reality of Geordi’s transformation, its emitters casting an otherworldly light over the signs of his physical decline. The holodeck’s doors are later forced open by Riker and Worf, revealing the aftermath of Geordi’s ordeal.
Building One in the Tarchannen Three outpost serves as the primary setting for Geordi’s holodeck simulation. Its interior walls capture the away team’s activities, including the mysterious shadow that persists after all crew holograms are removed. The building’s confined space amplifies the tension of Geordi’s investigation, its walls acting as a canvas for the shadow’s manifestation. The location is both a practical site for the simulation and a symbolic representation of the away team’s doomed mission, its eerie stillness mirroring the planet’s sensor-deadened terrain and the contagion’s stealth.
Organizations Involved
Institutional presence and influence
Starfleet is represented in this event through the Tarchannen Three Away Team Recordings, which Geordi loads into the holodeck for his investigation. The organization’s protocols and resources—such as mission logs, holographic simulations, and scientific analysis tools—enable Geordi’s forensic reconstruction of the doomed mission. Starfleet’s institutional knowledge and technological capabilities are critical to Geordi’s ability to isolate the unexplained shadow and extrapolate its shape, revealing the sentient force behind the transformations. However, the organization’s involvement also highlights its limitations, as the contagion defies conventional scientific explanation and Starfleet’s protocols fail to prevent Geordi’s transformation.
