Pyrovillia

Pyrovilia was the home planet of the Pyroviles, which was one of the 27 planets the Daleks transported to the Medusa Cascade, and one of only three planets in this operation that were not taken from 2009, instead being taken more than 2000 years earlier, why that was was never actually revealed. Presumably it was a hot and waterless world, like they intended the Earth to be after their invasion. (DW: The Fires of Pompeii)

By 2009, the disappearance of Pyrovilia was considered a cold case by the Shadow Proclamation. It was then discovered by the Doctor that the planet was stolen by the Daleks and put in the Medusa Cascade along with 26 other worlds. When the doctor and his companions had defetaed the Daleks and Davros they sent it back with all the rest of the planets to its rightful destination. (DW: The Stolen Earth/Journey's End)
