Master of the Land



The Master of the Land, also known as the Master, the Writer or the Controller, is the ruler of the Land of Fiction, enslaved by the Master Brain computer.

When the Doctor, Zoe, and Jamie were brought to the Land, the Master was an old man, who originally was a writer from Earth. As a writer on Earth he wrote about Captain Jack Harkaway. When the Doctor freed him, the Land of Fiction dissolved. (DW: The Mind Robber)

It is unclear what the true purpose of the Master is, whether it is to keep the Land simply functioning or to create new fiction to populate the land. To replace the old man, the Master Brain wanted to take over the Doctor and then take over Earth to absorb human imagination, in which the human race would be removed from Earth and adjusted to the Land, leaving the planet bare for(either the old man or the Brain) to take over.(DW: The Mind Robber)

Later The Monk reactivated the land and turned a boy (called Jason), from Earth in 1993, into the new Master of the Land. (NA: Conundrum)
