The Koll system was a star system of rain-soaked and muddy worlds that lied beyond the Outer Rim Territories on the Far Outer Rim, which separated Wild Space from the Unknown Regions. A very remote and isolated sun set, Kollawakianavianam I and Kollawakianavianam II, which were both shortened to "Koll" which created the name Koll system, provided little light and heat to planets such as Katarnakala, Skrawaller, Soloniama, Coruscant-2, Gaalanak, Hatsheput, and Naar.
