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 had the Space Station X-R built in orbit around Nowhere, it became the most secure secret prison in the empire. In the 300 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 it's 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 stations shields. The Humans put up a fight using their plasma-cannons, but they were outnumbered and outgunned. The Dalek Supreme was soon out of it's cell and attacked the crew and robo-guards from within. Within hours, every Human on the station had been exterminated and the Daleks were in control. (DWBIT: #33)
