The Ood-Sphere was the ice-covered homeworld of the Ood. It 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 Annual 2007) The world was home to the central export facilities of Ood operation.
History
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 3800s 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. After a battle and the intervention of the 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)
