Plurality/System

From Tymestl Wiki

A Plural System is simply the collective of individuals who live within and share a single body. System can refer to both the collection of individuals, and the body itself (as containing them).

Generally a Plural System has a name they've decided on to call themselves. What sort of name varies from System to System, sometimes being a proper name, other times being more of a description, and sometimes referring to a household or collective.
