Preplanis was a planet far from Earth. (The Space Trader) It had two moons. (His Majesty Smith; The Space Croppers) Lifeforms native to Preplanis included the bloop, the bog monster, the bush creature, cyclamen, the cyclops, fish, the lost civilization, and the star, as well as many plants. The planet was also the home of an enigmatic non-corporeal being nicknamed 'Mr. Nobody'. The Jupiter 2 crashed on Preplanis in 1997. (Island in the Sky) Over a year later, the planet's core was ripped open, destroying Preplanis. The disaster was caused by a miner named Nerim who was drilling for cosmonium.
