The Time Lords are humanoid beings inhabiting the 9th through 12th dimensions. They travel freely between all dimensions down to the 3rd. Evolved far beyond us biologically, technologically and spiritually, the Time Lords are capable of time-space travel, transmogrification of matter, planetary terraforming, and possibly even immortality.
Known by Kardashev, Kaku and others as members of a Type III or Type IV civilization, their primary pastime is playing God. Individual Time Lords may create worlds and use them as they please, as Earth children will do with an ant farm. Researchers surmise that our planet was created or at least populated by a Time Lord known variously through the ages as Odin, Ptah, Yahweh and simply, God. Another well-known Time Lord is Gord, of the planet Urth.
