Griffoth

Griffoth is the home planet of the Graske. As seen from orbit, Griffoth is a purple planet with grey scars which lead to the underground. The Graske live in the caverns of Griffoth, hollowing out tunnels which were connected by airlocks with puzzles. These tunnels lead to the stasis chambers of the Graske where they store the original copies of their changelings. (DW: Attack of the Graske)


 * The Doctor implies that there are carnivorous creatures on the planet who might eat the viewer. Griffoth is the first planet apart from Earth seen in the new episodes.
