Crinoth, hinted at being in the same solar system as Skonnos, (PROSE: Doctor Who and the Horns of Nimon) was a planet settled by the Nimon with the aid of Sezom. After it was drained of resources and energy, the Nimon planned to move to Skonnos, making the journey using the energy released by Crinoth when it died. They were defeated by the Fourth Doctor and Romana, and so were stranded on Crinoth when it disintegrated. (TV: The Horns of Nimon)
