Evacuation of the Dalek City

A temporary evacuation of the Dalek City occurred in the year 2066.

The Terrorkon
A specially-assigned correspondent from the Hyper-Space News Agency relayed a report to Earth about a Terrorkon who broke through an electric barrier and attacked several Daleks stationed at the Lake of Mutations. It stole a missile and went through an underground lake and into a cave deep in the mountains. After the missile was damaged by fallen rocks, the Dalek Prime ordered that the Dalek City be evacuated. News soon reached London offices from far out in hyperspace that the Emperor had commanded all Daleks to evacuate immediately in case of an explosion. A Red Dalek Leader, accompanied by the Emperor, followed the Terrorkon into the cave and successfully defused the missile, which had been discarded and accidentally activated by the creature for being inedible. The two of them watched as the Terrorkon was devoured by a giant eel, prompting the Emperor to call for an in-depth search of their homeworld in order to discover all its dangers.
