Ood Sphere
The Ood Sphere was the ice-covered homeworld of the Ood.
Astronomical Data
The Ood Sphere was located in the same star system as the Sense Sphere, which was in the Horsehead Nebula. (DW: Planet of the Ood, DWA: Doctor Who The Official Annual 2007) It was covered in mountains and high cliffs and seemed to be cold enough to have snow and permanent buildings made of ice. (DW: Planet of the Ood, The End of Time)
Hustory
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)
