Ood Sphere

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

Astronomical data
The Ood Sphere was a moon of a ringed planet, located in the same star system as the Sense Sphere, (home of the Sensorites), located in the Horsehead Nebula. (TV: Planet of the Ood) It was covered in mountains and high cliffs, had snow and permanent buildings made of ice. (TV: Planet of the Ood, The End of Time)

History
The Ood evolved and survived on the snowy moon in peace until the Second Great and Bountiful Human Empire arrived in the 39th century and enslaved them. The Ood were kept in Ood Operations on the moon, including the Ood Brain, which was found underneath the Northern Glacier of the moon. 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 moon, in peace once more. (TV: Planet of the Ood)

It only took the Ood a hundred years for them to establish fully a new Ood civilisation, with huge ice cities and a ruling council; returning to the level of civilisation in the 21st century of long before its contact with humanity. Alarmed, the Tenth Doctor realised something was causing them to advance so quickly. (TV: The End of Time)

The Eleventh Doctor visited the Ood Sphere to return fifteen Ood who had been unable to hear the song calling them home, (COMIC: Time of the Ood) one of which had settled down with Rory Williams and Amy Pond to serve them. (TV: Pond Life)
