Ebyssian

Ebyssian
Ebyssian is the homeworld of the Sanctar Hegemony. Situated far from the galactic core, it receives little attention from the galactic community. Ebyssian is the first planet from a brown dwarf called Vadai. The intense heat on one side of the planet and the extreme cold on the other make for violent storm cells wherever the sun is rising or setting. The indigenous Sanctar use large towers that catch lightning strikes and store their energy in capacitors.

Rindorr
Rindorr is Ebyssian's only moon. It is shrouded by a high-pressure atmosphere composed of carbon dioxide and sulphuric acids. The surface is composed of geologically young plains of volcanic basalts and rhyolites, with high concentrations of carbon and radioactives. Rindorr is highly volcanic; a dozen "supervolcanoes" 50-120 kilometers wide constantly erupt across the planet. Rindorr's carbon content and constant volcanism make natural diamonds plentiful, if extremely costly and dangerous to recover. It orbits Ebyssian exceptionally slowly and takes over 100 hours to complete a full circle. While eclipsed by Ebyssian, Rindorr's atmosphere is cool enough to make it temporarily hospitable. Once day breaks, the atmosphere heats up immensely. Mining operations must relocate multiple times within the day to prevent being caught in the sunlight.

Molgon and Tilgon
Molgon and Tilgon are Rothe Worlds; They are a pair of small and unusually dense terrestrial worlds that orbit each other so closely that they effectively share a single atmosphere. Although one cannot fly from one to the other both have identical atmospheres and substances from one often can be found on the other. Both worlds share an atmosphere of nitrogen and ethane. The surface is warm, and mainly composed of silica dust and dark basaltic rocks, with extensive deposits of heavy metals and radioactive materials. The tidal effects from the opposite planets result in constant high winds on both planets.
