Planet (Rise and Fall)

This unnamed planet had a native species in an accelerated time stream. This planet had grassy savannahs, rolling hills and a massive moon.

When the First Doctor and Ian Chesterton visited the planet, they watched a civilisation rise up from animals and then collapse in war. At the same time, the people centred their civilisation around the Doctor and Ian, who seemed to be ancient, immovable figures. (ST: Rise and Fall)
