Time Lords are a species from Doctor Who, with The Doctor himself being a Timelord. They were referenced in early episodes of Doctor Who but did not appear until the episode 'The War Games'. The Doctor had many adventures on Gallifrey (Timelord home planet) yet when the series relaunched in 2005, the time-lords were no more. They later were resserected in The End Of Time, but were soon gone once more.
