Kepler was once a place with intensive mining operations and ongoing scientific research undertaken in the local dark nebulae. But it was slowly changing for the worse and nowadays Kepler is just a poor, dirty and lowly populated place which only survives due to the occasional trade between Liberty and Kusari when traders are passing through this System.
Advice to all visitors is to stay only in the Trade-Lane Corridors and use the services of the Ames Research Station if needed because the local dark nebulae strongly disrupted a ship's long-range communication system. The local criminal group Xenos using this to their advantage. Rumours abound, that somewhere deep in the local asteroid fields, an old abandoned asteroid-station still exists from mining times; which they maybe using as their operational base.
