>>55321408It refers to a period between the original colonial mission vanishes from living memories (~4000 AST?) to Despina uniting for good after the discovery of crystallized vitubium (~37000 AST?) allowing communication and maybe electronics survive the major flares of the host star Sestag. It’s called that because this period is dominated by periodic rise and fall of civilization due to the solar flares that wipe out civilization on a semi-regular basis and many knowledge about that period is lost to time as a result. It probably also leaves some kinda collective trauma to the population that still shapes the cultures to this day
