Box

Summary
Box is the descriptively named spirit that inhabits the Duplibox. Whenever a living creature is duplicated by the Duplibox, the spirit's current knowledge and memories are "copied" into the duplicate, allowing them to control it. Because Box is "copied" each time this happens, multiple duplicates do not share knowledge with each other. However, whenever a duplicate dies or decays, that copy of Box returns to the Duplibox, where their memories and knowledge re-coalesce. To this end, Box is still essentially one entity, and does not die just because a duplicate does.

Box is not actively aware of any knowledge or memories the duplicate possessed, but is suddenly instinctively aware of them only when relevant, allowing them to perfectly imitate the person the duplicate is copying. Unfortunately, any knowledge gained in this way is lost fairly quickly, so Box can't permanently remember every secret a person has.

When there are no duplicates, Box is effectively "asleep." As part of an arrangement with Mutie Zone, Box requires at least one duplicate to control at all times. In return, Box will help out Mutie Zone, but they consider themself an ally, not a member.
