One battered Kill Cruiser and three Dalek occupants escaped the destruction of Davros' fleet as the Reality Project came to an end. In desperation, they located the final remaining Progenitor Device which was a dimensionally transcendental capsule that contained original Kaled genetic material from which a new race of Daleks could be created.
The progenitor device would not recognise the purity of Davros' newest creations and so a second trigger was required – the testimony of The Doctor that these were indeed Daleks. Once this testimony was received, the device activated and spawned the first five Daleks of this new race. The Paradigm Daleks that emerged exterminated the three survivors as they were impure. Their next act was to trick The Doctor into allowing them to live by threatening the planet Earth with an Oblivion bomb. The Paradigm then piloted the ship through space and time to an unknown location from which they could build a new Dalek homeworld and a whole new Dalek race.
