Arctic zone, Centuria
From Tardis Wiki, the free Doctor Who reference
The arctic zone of Centuria was located in the planet's northern hemisphere. It was sparsely populated by people, since Centuria was primarily a human holiday colony, but was rich with the natural resource hargstone. The region was also home to the planet's native ice snakes.
In the 41st century, Cybermen created a large number of semi-human cyber-drones, who they sent to mine the hargstone. These mines were eventually sealed by Homaj while the Tenth Doctor and Jayne Kadett made their escape. (COMIC: Enemy Mine)
