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.

Marco Polo
primary

Unknowingly vulnerable (off-screen, oblivious to the danger)

Supporting 3

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.

Goals in this moment
  • To receive the TARDIS as a gift from Polo (unaware of the betrayal)
  • To maintain his dominance over rival khanates like Noghai’s
Active beliefs
  • Polo is a loyal envoy bringing him a valuable gift
  • Noghai’s rebellion is a distant threat, not an immediate concern
Character traits
Symbol of imperial authority (contrasted with Noghai’s rebellion) Unwittingly connected to the conspiracy (his gift is being stolen) Distant and abstract (not physically present, but a looming political force)
Follow Kublai Khan's journey
Malik
secondary

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.

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.

Goals in this moment
  • To capture and silence Barbara as a threat to the conspiracy
  • To enforce Tegana’s orders without question
Active beliefs
  • Barbara is an enemy spy who must be neutralized

TARDIS (Time and Relative Dimension in Space)

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.

Mongol Bandits (Tegana's Military Faction)

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.

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.

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).
