Pyrovillia

Pyrovillia was the home planet of the Pyroviles, which at some point in the Pyroviles' history was lost. Presumably it was a hot and waterless world, like they intended the Earth to be after their invasion. (DW: The Fires of Pompeii)


 * Lucius said it was taken from the Pyroviles, suggesting it was either destroyed in conflict or taken over by an empire.
