Pyrovillia
From Tardis Wiki, the free Doctor Who reference
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.
