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)

In The Stolen Earth, The Doctor discovers that Pyrovillia had been stolen by the Daleks. This is one of the 27 planets the Dalek's stole to make a powerhouse.
