Magranite 4
From Tardis Wiki, the free Doctor Who reference
Magronite 4 was a planet located in Ecto-Space in the Hanamar system. It was oppressed by the warlord Kebek and also faced an outbreak of Showard syndrome. The Mistress and K9 once visited Magronite 4, harnessing research that the inhabitants of Magronite had already been carrying out using the mineral cypherdurite to develop a lasting antidote for the disease. However, in the process, she brought Kebek's ire on herself and K9, forcing the two to take refuge at Emperor Lukor's palace on Jokastarna. (AUDIO: The Choice)
