NPC

undefined:

NPCs (short for non-playable character) are constructs that are found in a system's headspace but are not part of the system itself or are notable distinct from other headmates in their autonomy, sentience, elaboration, or interaction.

NPCs may serve to make the headspace feel more realistic, or fill in roles from a headmate's inner world history, e.g. a co-worker or family member.

The term is used with slightly differing definitions:
 * a soulbonding-analogue to fragments and other "not-fully fledged" members (coined by Hawkeye Erron).
 * a non-fronting member.
 * a non- or semi-autonomous headspace entity that is not active when not interacted with; this is mentioned as not being exclusive to systems.
