Shell

A Shell is an artificial body that is created to look exactly like the original. This permits a person to be in multiple places at once. All shells belonging to a given person are mentally linked with the original and each other to permit memory and personality syncing. All shells have an amount of "filling" that increases as it is used. The 3 most common types are full, partial, and empty.

A Full Shell is, for all intents and purposes, are indistinguishable from the original. The only notable difference between a full shell and the original is that all shells (including the full ones) are sterile.

An Empty Shell is a shell that is visually and physically indistinguishable from the original but does not have memories or personality cached on their system. As a result, they are usually used a remote control body that can be controlled by a full shell or the original, but when doing so loose most or all of their awareness of their surroundings and control of their main body since their brain is controlling the remote empty shell. Most empty shells are able to follow (very) simple commands such as following someone. Some empty shells are able to summon the attention of a full shell or the original if they hear a key phrase or something like that.

A Partial Shell is a mix of an empty and a full shell. It is able to act and think properly mostly on its own, but require a share of attention from a full shell or the original. The amount of attention needed varies depending on how "filled" the partial shell is.

All of the shells require some passive power from the original to run. If the original dies, all of the shells slowly stop working.
