Kegron Pluva was a planet which, according to the Ninth Doctor, had the "maddest ecosystem in the universe". It had nine moons, six of them orbiting the opposite way to the other three, as well as a sun orbiting it. One year on the planet had 43 seasons. The water on Kegron Pluva was solid. The indigenous life was described by the Doctor as "a kind of dog-plant-fungus thing", whose diet included "a kind of metal plum".
The Ninth Doctor intended to take his companions Rose Tyler and Jack Harkness to Kegron Pluva, but the visit had to be postponed when he discovered a temporal distortion coming from 2005 Bromley. (PROSE: Only Human)
