Rezn'a is the native world of the Rezn'arian species. It was originally inhabited by unicellular species and microscopic organisms. Over millenia, these organisms evolved into Rezn'arians. The species started as hunters. During the Mandolorian Wars, renogade Jedi hid on the planet. The Jedi adapted to the cold, snowy climate and made peace with the natives. A small space battle was fought over Rezn'a during the Clone Wars with the Republic being victorious. No record is known of it being occupied during this time.
