At the height of the Dalek Empire before the Last Great Time War, a fleet of freighters carried plundered resources across the universe. The Daleks were constantly in search of new planets to strip of their resources for their Empire. Dalek saucer X-K Beta-19, coming out of hyper-drive, comes across Galacton (third planet around a sun). Detecting a high level of Radio-Activan at the planet's core, the Daleks decide to drill into the core, energise it and use it as fuel for the Dalek Seventh Fleet.
