Zolfa-Thura

Zolfa-Thura was a desert world in the Prion system, devoid seemingly of life.

History
its apparent lifelessness was a result of a war between the Zolfa-Thurans over the Dodecahedron. During the war, nearly all of the Zolfa-Thurans were killed and the planet was turned into a desert. Meglos was the only survivor. He returned the Dodecahedron to Zolfa-Thura from Tigella and planned to use its power to destroy other planets. However, the Doctor reverted the controls so that the Dodecahedron destroyed Zolfa-Thura instead. (DW: Meglos)
