Nowhere

Nowhere was the most isolated planet in the Mutter's Spiral, tucked into an anti-matter reef between the Blore Wilderness and the Gulf of Null.

History
The Earth Empire built Space Station X-R in orbit around Nowhere. It became the most secure secret prison in the empire. In the three hundred years since the Dalek-Human War had begun, only one Dalek Supreme had ever been captured alive. It was sent to Space Station X-R. The Empire had mistakenly thought the Daleks would never find it. The captured Dalek, code-named "Prisoner One", was only in its proton-cell for two days when the rescue mission arrived. Using a warp-sling transmat to launch themselves through deep space, the Daleks wasted no time in destroying the station's shields. The humans fought with their plasma-cannons, but they were outnumbered and outgunned. The Dalek Supreme was soon out of its cell, attacking the crew and robo-guards from within. Within hours, every human on the station had been exterminated and the Daleks were in control. (PROSE: Prison Break!)
