Ran Dan's Folly, a mining colony, existed on the planet Sunspot within the Tython system. This planet based outpost was dedicated to the extraction of petonium and marionium, both elements valuable for their energy-producing properties. Tragically, in 25,823 BBY, a calamitous accident led to the death of one hundred miners. Subsequently, in 25,811 BBY, the colony experienced a labor strike. By 25,793 BBY, it had been completely deserted.
