Astronomical data
As seen from orbit, Griffoth was a purple planet with grey scars which led to the underground. It was inhabited by dangerous predators, as well as the Graske. The Graske lived in caverns, hollowing out tunnels which were connected by airlocks with puzzles. These tunnels led to the stasis chambers of the Graske, where they stored the original copies of their changelings. (NOTDWU: Attack of the Graske)
