=== World Generation Tables === ==== Acheronian ==== ''Terrestrial Group, Telluric Class, Acheronian Type.'' <br/> <small>These are worlds that were directly affected by their primary's transition from the main sequence; the atmosphere and oceans have been boiled away, leaving a scorched, dead planet.</small> :Size: 1d6+4. :Atmosphere: 1. :Hydrosphere: 0. :Biosphere: 0. ==== Arean ==== ''Dwarf Group, GeoCyclic Class, Arean / Utgardian / Titanian Types.'' <br/> <small>These are worlds with little liquid, that move through a slow geological cycle of a gradual build-up, a short wet and clement period, and a long decline.</small> :Size: 1d6-1. :Atmosphere: Roll 1d6.
