This is a space around the upper chest area, which links to a larger space containing many Identities.
If Ultimate-self is present, then Ultimate-self has a connection which is an infinite-line down to the top of the Identity-space.
At the top of the Identity-space is a label which is the name of the Identity (Terminal in a Game) and links to related structures elsewhere. At the bottom of the Identity-space, there are connections to other body-systems and downwards to Morphic-fields.
This forms the identity for the body, as a label for the Piece in the Physical-universe Playing-field.
An improved state for the Identity-space uses the availability of all possible Identities, inside the Identity-space, rather than a specific set of Identities there.
