Mask of Bara
The Mask of Bara is the "bottle" that Bara sealed herself in upon absorbing the memories of the late goddess Ema. Within it, Bara created a personal paradise by hiding away the bad memories she received directly outside the mask imbued in its metal. The mask began to become associated with negativity as those who touched became imprinted as the owner, unable to part with the mask until their death ten days later. Throughout that time, the mask's owner suffers from hallucinations and vivid nightmares, being mentally tortured until the timer runs out. As a result, myths and superstition spread about the mask, and some believed that the mask would steal your soul.
Unlike many would believe, Bara is actually not malicious. Her reason to do this was to scare others away in hopes that no one would release her back into the real world.
