The inhabitants of the planet Gallifrey, the Time Lords were the most noble and mighty race in the universe. They swore never to interfere in the actions of other peoples and other planets, only to watch and observe. Over their many years on screen, they have both helped and hindered our favourite Time Lord, The Doctor; notably, tasking him with preventing the Daleks from being created, and also putting him on trial for his meddling throughout time and space!
The Time Lords have also been shown to have a dark side, too, with them using every forbidden weapon in their vaults during the Time War, and also their use of the "Crack in the Wall" to plague the Eleventh Doctor all through his life - trapping him on Trenzalore for 900 years! Though they were supposedly destroyed at the end of the Time War, they've often been saved or found other ways of surviving. That is, until they get killed off again!
But how much do you actually know about the ancient race of Gallifrey-dwellers that is the mighty Time Lords?
