Concord

undefined:

A concord is a headmate, identity, trait, concept, function, etc. that is shared among a system, sisasystem, or group or that all or most members are deeply connected to or feel represented by. This may be something all members originated from or are directly connected to, something that is shared, or even the intersection of all members within such a group.

Not all systems or interbal group may have a concord, and a polyplex may have a concord along with each of their sisasystem also having their own distinct concord.
