Ood Sphere

The Ood Sphere was the ice-covered homeworld of the Ood.

Overview
The planet was covered in mountains and high cliffs and was in the same solar system as the Sense Sphere, home to the Sensorites (DW: Planet of the Ood), located in the Horsehead Nebula. (DWA: Doctor Who The Official Annual 2007)

The Ood evolved and survived on the snowy planet in peace until the Second Great and Bountiful Human Empire arrived on the planet in the 39th century and enslaved the race. The Ood were kept within the presence of Ood Operations on the planet, including the Ood Brain, which was found underneath the Northern Glacier of the planet. In 4126, after a rebellion and the intervention of the Tenth Doctor, Donna Noble and the Friends of the Ood, the Ood were freed and left to roam the planet, in peace once more. (DW: Planet of the Ood). It only took the Ood 100 years for them to have fully established a new Ood civilization, with huge ice cities and a ruling council. (DW: The End of Time).
