Like all Eden Planets it is very similar to earth, with a breathable atmosphere and large landscapes. The planet is a bit bigger than earth and have nearly the same percent of land mass.
In 2067 a satellite from the Earth Research Department reached the Corra system and disovered the planet. In 2070 a stolen ship landed illegally with 12 people on the planet. Their dead corpes were found 9 months later by a reconnaissance drone. The reason for their death was unknown so the researcher assumed that the environment killed them. Nowadays it is presumed that they killed each other and the last survivors starved. After getting the Prime status in 2072 it was allowed to research on the planet.
