Who Was There
Characters present in this moment
Determined and focused, with a hint of skepticism toward Tegana’s past performance
Acomat is Tegana’s equal in the conspiracy, acting as Noghai’s representative to finalize the ambush plan. He questions Tegana’s past failure at Lop but ultimately defers to his authority, confirming the attack on Polo’s caravan and the seizure of the TARDIS. His dialogue reveals his strategic mind and his understanding of the TARDIS’s value to Noghai’s army. He is the voice of Noghai’s expectations, ensuring Tegana’s actions align with the larger rebellion.
- • To ensure the TARDIS is captured for Noghai’s army
- • To hold Tegana accountable for his failures (e.g., Lop)
- • The TARDIS is the decisive asset in Noghai’s war against Kublai Khan
- • Polo and his companions are obstacles that must be removed
Fearful and desperate (as she is grabbed and screams)
Barbara is the unwitting eavesdropper whose discovery by Malik and the Mongol guard escalates the tension. She is captured in the outer cave after overhearing Tegana and Acomat’s plot, her scream marking the shift from strategic planning to immediate crisis. Her presence symbolizes the group’s vulnerability and the fragility of their secrecy, as her capture now endangers the entire caravan.
- • To uncover the truth about Tegana’s betrayal
- • To warn Polo and the Doctor of the impending ambush
- • Tegana cannot be trusted, and his loyalty to Polo is a lie
- • The TARDIS is in grave danger of being seized by Noghai’s forces
Unknowingly vulnerable (off-screen, oblivious to the danger)
Marco Polo is not physically present in this event but is a central figure in the conspirators' discussion. His name is invoked as the leader of the caravan transporting the TARDIS to Kublai Khan, and his fate is casually determined—his execution is confirmed by Tegana. Polo’s absence underscores the vulnerability of his position; he is unaware of the impending betrayal and the danger his companions now face.
- • To reach Kublai Khan’s court with the TARDIS and secure his freedom from exile
- • To protect his caravan and companions from unseen threats
- • Tegana is a loyal member of his caravan
- • The TARDIS is a valuable gift for Kublai Khan, not a weapon for Noghai’s army
Calculating and in control, with a hint of irritation at the interruption
Tegana is the mastermind of the conspiracy, orchestrating the ambush on Polo’s caravan and the seizure of the TARDIS for Noghai. He defends his past failure at Lop with a sandstorm excuse, reaffirms his loyalty to Noghai, and coldly confirms Polo’s execution. His demeanor is calculating, and his authority is unchallenged until Malik interrupts with the news of Barbara’s presence. Tegana’s reaction is swift and ruthless, ordering her capture without hesitation.
- • To secure the TARDIS for Noghai’s army to ensure his invincibility
- • To eliminate Polo and his companions to remove witnesses and obstacles
- • The TARDIS is the key to Noghai’s victory over Kublai Khan
- • Polo and his group are expendable obstacles in Noghai’s path to power
N/A (off-screen, symbolic presence)
Kublai Khan is mentioned indirectly as the intended recipient of the TARDIS in Polo’s caravan. His authority is invoked as the ultimate destination for Polo’s journey, but his court is now a distant and unreachable goal due to Tegana’s betrayal. Kublai Khan’s name serves as a symbol of the power struggle between him and Noghai, with the TARDIS as the coveted prize.
- • To receive the TARDIS as a gift from Polo (unaware of the betrayal)
- • To maintain his dominance over rival khanates like Noghai’s
- • Polo is a loyal envoy bringing him a valuable gift
- • Noghai’s rebellion is a distant threat, not an immediate concern
Alert and focused, with a sense of urgency
Malik is the alert and deferential intermediary who interrupts the meeting to reveal Barbara’s presence in the outer cave. His observation skills and loyalty to Tegana are evident as he quickly identifies the threat and alerts the group. His role is that of a watchful subordinate, ensuring the conspiracy remains secure. His interruption forces Tegana to shift from planning to immediate action, capturing Barbara.
- • To ensure the conspiracy remains undiscovered
- • To support Tegana’s mission by eliminating threats (like Barbara)
- • Barbara’s presence is a direct threat to the plan
- • Tegana’s authority must be upheld at all costs
Stoic and focused (no emotional reaction shown)
The unnamed Mongol guard is the silent enforcer who captures Barbara upon Malik’s alert. His presence is a physical manifestation of the conspiracy’s security measures, ensuring no outsiders interfere. His action—grabbing Barbara and forcing her scream—marks the moment the conspiracy transitions from planning to execution, with real consequences for the caravan.
- • To capture and silence Barbara as a threat to the conspiracy
- • To enforce Tegana’s orders without question
- • Barbara is an enemy spy who must be neutralized
- • Tegana’s authority must be upheld through action
Objects Involved
Significant items in this scene
The TARDIS is the central object of desire in this event, described by Tegana as a 'caravan that flies' belonging to an 'old magician' (the Doctor). Its strategic value is emphasized by Acomat, who notes that with such a caravan, Noghai would be 'invincible.' The TARDIS is not physically present in the cave but is the driving force behind the conspiracy, as its seizure is the primary goal of the ambush on Polo’s caravan. Its mention shifts the discussion from logistics to the high stakes of the rebellion, framing it as the ultimate prize.

Location Details
Places and their significance in this event
The Outer Cave is the transitional space where Barbara is discovered eavesdropping. It serves as the entry point to the Inner Chamber, making it a vulnerable area where secrecy can be compromised. The Mongol guard’s presence here underscores the cave’s role as a guarded perimeter, ensuring no outsiders infiltrate the conspiracy. Barbara’s capture in this space marks the moment the conspiracy’s security is tested and found wanting, forcing Tegana to act swiftly.
The Cave of Five Hundred Eyes is the physical setting for this event, a dimly lit and eerie space where the conspiracy unfolds. Its carved eyes symbolize watchfulness, adding to the tension as Barbara eavesdrops and is captured. The cave’s inner chamber serves as the hub for Tegana and Acomat’s planning, while the outer cave becomes the site of Barbara’s discovery. The location’s atmosphere is one of secrecy and danger, with the eyes acting as silent witnesses to the betrayal.
Karakorum is mentioned indirectly as the destination of Noghai’s advancing army, where he awaits news of Tegana’s success. It serves as the symbolic stronghold of Noghai’s faction, representing the political and military power he wields. The location is invoked as a reminder of the stakes—failure for Tegana means Noghai’s disappointment, while success ensures his army’s dominance. Karakorum looms as the ultimate prize, the seat of power Noghai seeks to claim with the TARDIS.
Shang-Tu is mentioned as the location where Tegana plans to ambush Polo’s caravan and seize the TARDIS. It serves as the tactical site for the conspiracy’s execution, chosen for its strategic value along the caravan’s route. The location is invoked as the point of no return—once the ambush occurs, Polo’s fate is sealed, and the TARDIS will be in Noghai’s hands. Shang-Tu represents the culmination of the conspirators’ planning and the beginning of their victory.
Organizations Involved
Institutional presence and influence
Mongols (Tegana’s Faction) are the active participants in the conspiracy, acting as Noghai’s proxies to sabotage Polo’s caravan. Tegana, as their leader, commands their loyalty and directs their actions, including the ambush at Shang-Tu and the capture of Barbara. The faction’s role is to execute Noghai’s orders with precision, ensuring the TARDIS is seized and Polo is eliminated. Their presence in the Cave of Five Hundred Eyes symbolizes the infiltration of Noghai’s influence into Polo’s caravan, turning trusted allies into enemies.
Kublai Khan’s Court is invoked indirectly as the intended destination for Polo’s caravan and the TARDIS. The court represents the established order that Noghai’s rebellion seeks to overthrow. Polo’s loyalty to Kublai Khan is contrasted with Tegana’s betrayal, framing the conflict as a struggle between tradition (Kublai Khan) and rebellion (Noghai). The court’s authority is unwittingly undermined by the conspiracy, as the TARDIS—meant as a gift—is instead being stolen for Noghai’s use.
Noghai’s Army is the ultimate beneficiary of the conspiracy unfolding in this event. Represented by Tegana, Acomat, and Malik, the army’s goals are advanced through the seizure of the TARDIS and the elimination of Polo’s caravan. The army’s march toward Karakorum is invoked as a looming threat, with Noghai awaiting news of Tegana’s success. The organization’s power dynamics are clear: Noghai’s authority is absolute, and his subordinates (Tegana, Acomat) operate with ruthless efficiency to secure his victory.
