|embelian (n., adj.)|
|Applies to||systems, headmates, system functions|
An embelian is a unitian in which individual members already existed before the unit as separate members, and only unify under certain circumstances, often willingly. Because of this, they may be together often, or hardly at all, depending on if it’s currently needed.
The adjective is "embelic” and can be used to describe systems as well (ex: an embelic subsystem).
