The Planet

The Ogron Planet was a barren planet, inhabited by the Ogrons and used as a base by the Master.

Astronomical Data
The Ogron Planet was located at galactic coordinates 0110011 by C2 (EDA: Interference - Book One) or at 2349 to 6784 (DWN: Doctor Who and the Space War). It was a rocky world, with little in the way of valuable minerals and very little vegetation. Native creatures include the Ogrons and their predator. (DWN: Doctor Who and the Space War)

History
It is believed that in the distant past there was drastic change in climate, leading to the odd combination of traits in the Ogrons. (MA: The Romance of Crime, PDA: Mission: Impractical)

In 2540, the Master used the Ogron planet as a base for his attempts to create unrest between the Draconian empire and the Earth Empire. When Third Doctor got involved, the Ogrons kidnapped Jo Grant and brought her back to their planet. She was allowed to escape and use the communication devices, which the Master used as a trap to lure in the Doctor. When the combined Human/Draconian forces came to the planet, they were attacked by the Ogrons, until they were scared off by an Ogron eater. The forces are then captured by the arriving Daleks. They were eventually able to escape, planning to return with a proper army. (DWN: Doctor Who and the Space War)
