Master's Time Ram Control Dial

Brass-plated mechanical control dial unique to the Master's TARDIS, responding to grotesque Time Ram glyphs and forcing temporal alignment with other vessels

2 appearances

Purpose

To manually activate and control the Time Ram mechanism, forcing temporal compression between two TARDISes to trap them in shared space.

Significance

This dial represents the final gambit in the Doctor's battle against the Master, a contested control point where desperation trumps reason. Its activation decides whether millions die in temporal collapse or whether two lifelong rivals face each other in enforced proximity. Jo's attempted intervention through this control marks her evolution from observer to active participant in the Doctor's temporal conflicts.

S9E26 · The Time Monster Part 6

Kronos offers deliverance to Doctor and Jo

The Time Ram Control Dial on the Master’s console is adjusted to lock both TARDISes on the same frequency. As the number rises towards the red line, it vibrates violently under temporal friction, responding to Jo’s attempt to seize control.

Before: Set just below the red threshold at 90

After: Increased to beyond the red line at 94, triggering the catastrophic time ram collision

Before: Set to resist the Doctor’s lock, under the Master’s control

After: Overridden and immolated in the void, physically scarred and discolored
