Master’s TARDIS Filing Cabinets (Colony in Space Evidence)

The four-draw metal filing cabinets are the primary containers of the Master’s secrets, housing the mineralogical survey reports and the Adjudicator’s credentials. They serve as a physical barrier to the truth, requiring the Doctor and Jo to actively search and uncover the evidence within. The cabinets’ role is functional—they store the Master’s documents—but their narrative significance lies in what they conceal. Their presence in the TARDIS underscores the Master’s need for secrecy and control, while their contents become the key to exposing his deception.
