Nepmos is a resource-rich terrestrial world somewhat larger than Earth, with a dense atmosphere of sulphur dioxide and argon. Nepmon' crust is very thin and unstable, not more than 8 kilometers deep in any location. Subsurface magma flows are a hazard to ground travel, and earthquakes are frequent. While heavy metals and radioactives are plentiful, this geological instability has deterred investment by mining concerns.
An additional complication is that the Styx Cluster lies uncomfortably close to the "Five Kiloparsec Ring" around the galactic core. The Ring contains a great deal of molecular hydrogen, fueling the majority of the galaxy's star formation. This area is too dangerous to safely travel.
