a warrior greater than either", which is "half-Dalek, half-Time Lord", while in "Hell Bent" (2015), the General, while describing the prophecy of the Hybrid, mentions the Time Lords as one of two warrior races along with the Daleks. In "Before the Flood" (2015), the Fisher King describes the Time Lords as "Cowardly, vain curators, who suddenly remembered they had teeth, and became the most warlike race in the galaxy." In the very distant past, the Time Lords fought a genocidal war against the Great Vampires, which led to such a catastrophic loss of life that the Time Lords renounced violence. In The War Games, the Second Doctor mentions that the Time Lords' "great powers" are hardly ever used due to their policy of non-intervention into the affairs of other planets, and that they instead observe and gather knowledge. Because of this, holding a trial is a "very rare" event for the Time Lords. Exceptions to this policy are made only in extreme circumstances when they feel they have to, such as where the Doctor calls them for help in the serial. At the start of the 2005 television series, Gallifrey was thought to have been destroyed and the Time Lords functionally extinct as a result of a mutually destructive Time War with the Dalek race; the Ninth Doctor describes his planet as "just rocks and dust" in "The End of the World" (2005), and mentions in "Dalek" (2005) that the Time Lords "burnt" with the Daleks at the end of the "Last Great Time War", and the Tenth Doctor tells the Master in "The Sound of Drums" (2007) that the Time Lords are "dead" and "[a]ll [they've] got is each other." The Doctor describes himself as the last of his kind and says his planet burned on numerous other occasions, as do other individuals, such as the Krillitane Mr Finch in "School Reunion" (2006). In "Father's Day" (2005), the Ninth Doctor remarks that before Time Lords were "all gone", they would have prevented or repaired paradoxes such as that which attracted the Reapers to 1987 Earth. In "Rise of the Cybermen" (2006), the Tenth Doctor mentions, "When the Time Lords kept their eye on everything, you could pop between realities, home in time for tea. Then they died, and took it all with them. Walls of reality closed, the worlds were sealed. Everything became that bit less kind." In "The
