Partial-Core

Partial-Core:

The partial-core is a headmate with a partial connection to the body's pre-plural self. If the core is the headmate with the most connection to the pre-plural self, the partial-core is the headmate with the second, third, (etc) most connection.

Like the core, not every system has one. The partial-core often inherits the personality, identity, and/or memories of the pre-plural self.
