The Ogron planet was the barren homeworld of the Ogrons. (TV: Frontier in Space, PROSE: Interference - Book One) By several accounts, the planet was called Orestes by outsiders (PROSE: So Vile a Sin, Mission: Impractical) but known to the Ogrons as Braah. (PROSE: The Romance of Crime, Mission: Impractical) However, some sources indicated that the Ogrons called it the Planet because they were too simple-minded to give it another name. (AUDIO: Planet of the Ogrons, Too Many Masters)
Astronomical data[]
The Ogron planet had high gravity and was located on the outer extremity of the Mutter's Spiral (PROSE: The Romance of Crime) at galactic coordinates 0110011 by C2 (PROSE: Interference - Book One) or at 2349 to 6784. (TV: Frontier in Space) It was actually a moon of the gas giant Clytemnestra along with Aegisthus, Electra, and Iphigenia. (PROSE: So Vile a Sin)
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 (TV: Frontier in Space) which may have been their "canyon gods." There was a lack of food on the planet, and the atmosphere contained more hydrogen than Earth's. (PROSE: Mission: Impractical)
History[]
It is believed that in the distant past there had been a series of rapid, drastic changes in climate, leading to the odd combination of primate and carnivore traits in the Ogrons. (PROSE: The Romance of Crime, Mission: Impractical)
The Ogron planet was first discovered by outside intelligences in 1855 by the Human calendar. (PROSE: Interference - Book One)
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 the 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 were then captured by the arriving Daleks. They were eventually able to escape, planning to return with a proper army. (TV: Frontier in Space)
The Ogrons were first taken off their homeworld by the Daleks and served them out of fear; as a result, the Earth and Draconian Empires spared them and eventually employed them. (PROSE: Mission: Impractical) C. 2976 the planet had been colonised by the Earth Empire and a war ensued between the Empire and the Ogrons. (PROSE: So Vile a Sin)
Many generations after working with the Master, a group of Ogrons captured the Monk and Missy, bringing them to the Planet and seeking reparations. The pair eventually escaped in the former's TARDIS, after starting a slave rebellion and dematerialising in the wake of the damaged they had caused in the city. (AUDIO: Too Many Masters)
During the Last Great Time War the Daleks rewrote history so that they used Ogron mercenaries during a number of skirmishes with the Doctor, but did not rewrite it enough so that their outcomes changed. They also established a base on the Planet, where The Overseer conducted experiments on several Ogrons. The base was eventually destroyed by the Eighth Doctor and The Twelve, with the help of Bliss and Doctor Ogron. (AUDIO: Planet of the Ogrons)
