All paper-thin embedded characters exist only barely in three dimensions as a carving on some sort of surface, like a wall or table, with moving eyes. They live in anguish every moment until pried loose from their place of imprisonment. The life spans of Embedded Characters once released from captivity are very short. In a month or six weeks, they erode away into nothingness. Despite the eventual death, embedded characters find that the greatest gift they can received is to be unembedded, where they can now travel to where they may. Extremely brittle, a minute stumble to the ground or a crash into an object may quickly shatter these beings into dust.
