Hash50: The Empire of Sanctuary is set in a world where humanity resides within a vast dome, created 200 years ago by a celestial tortoise that descended from the heavens. This dome protects humanity from the deadly mutants—once plants and animals—transformed by a cataclysmic seven-day red rain. The Hash50 unit, led by the determined Abel, is responsible for venturing outside the dome to retrieve Shard Stones, which are essential to maintaining the force field and ensuring humanity’s survival.
