Miasimia Goria

Miasimia Goria was a planet ruled over by the Rani, a renegade Time Lord and brilliant scientist. The people enslaved under her, Miasimia Goria's inhabitants, became restless and aggressive as a result of her experiments. She then travelled to Earth to extract chemicals out of human brains for her experimentation (DW: The Mark of the Rani).

Behind the Scenes
Miasimia Goria is a completely different planet to Melissa Majoria, where bees originated from, and which was later stolen and placed in the Medusa Cascade (DW: The Stolen Earth).
