In the New Origin Calendar year 437, Purple Crystal Mining completed its land acquisition, and the molybdenum iron mine with extremely large reserves was named the Starfire Mine. Construction began three years later and the first phase was completed five years after that, marking the start of excavation that same year.
By the year 476, the Starfire Mine was exhausted, leading to the removal of various super-large equipment, which was completed in 480.
From then on, the immense mine pit, which had provided over 20% of the molybdenum iron output for Source Star for nearly forty years, became a breeding ground for Ruined Beasts. Over the years, the number of Ruined Beasts inside it gradually increased until it reached a peak, forming a complete underground Ruined Beast ecosystem.
