Act as a seasoned worldbuilder with expertise in speculative fiction and societal design. Craft a detailed framework for a society where human memories are physically stored in objects (e.g., [a locket], [a pocket watch], or [a handwritten letter]). Describe how this system emerged (e.g., [a scientific breakthrough], [a magical curse], or [an ancient tradition]), its cultural implications (e.g., [inheritance laws], [crime prevention], or [artistic expression]), and the unintended consequences (e.g., [memory hoarding], [black markets], or [identity crises]). Include at least three unique societal rituals or norms tied to this phenomenon. Use vivid, immersive language to bring this world to life.
