TARDIS Time Vector Generator Mercury Fuel

Critical liquid mercury fuel for the TARDIS's time vector generator, distinct from external mercury sources. Its depletion in The Wheel in Space (Parts 1 and 4) strands the TARDIS, necessitating the Doctor's later acquisition of an alternative mercury source (the 'Doctor's Bottle of Mercury') for sabotage purposes.
