Marco Polo's Caravan
A large-scale desert caravan led by Marco Polo, consisting of multiple wagons (including transport shelters with cots), horses, and guarded supplies. The caravan serves as a mobile base for travel across the Gobi Desert, with its wagons housing critical items like the TARDIS key and temporary resting cots. The caravan's decline is a recurring narrative theme, symbolizing exhaustion and decay amid the group's survival struggles. Tegana overhears discussions about the TARDIS key's location within the guarded wagons, while the Doctor's collapse and rejection of the wagon cot underscore the caravan's primitive limits compared to the TARDIS. The caravan's hardships contrast with the TARDIS's superior technology, highlighting the group's reliance on both systems.
