Miller's Wooden Cart

The sturdy wooden cart, normally a mundane conveyance for goods around the estate, becomes an instrument of alien domination. The Terileptil uses it as a mobile platform to transport infected machinery toward the laboratory beneath London, its wheels rattling over gravel as it carries a cargo now warped by soliton gas machinery.

The miller's cart serves as an innocent but crucial environmental detail that corroborates the Terileptils' surface operation while unintentionally aiding their secrecy. Its presence outside the hidden base location serves as partial camouflage, masking the advanced technology operating beneath while maintaining the facade of normal 17th-century activity.

The miller's cart stands parked outside the bakery, its presence immediately triggering the Doctor's deduction about the miller’s whereabouts. As a literal clue to the unseen occupant inside, the cart becomes the catalyst for the team’s entry into the bakery. Its functional role as a working vehicle subtly underscores the mundane normalcy disrupted by alien intrusion.

Mace rumbles the miller’s cart away from the spreading fire to protect it, ensuring the vehicle doesn’t become part of the inferno while villagers scramble to fight the flames.
