Pleroma (πλήρωμα): The fullness of divine reality , where all existence is whole and complete beyond the illusions of the material world.

In the ancient sense , the "watchers" were guardians, aware but neutral. In the context of a group egregore , this watchfulness can take on a more controlling role — overseeing and subtly guiding the group's actions in ways that constrain individuality and lead to conformity , even to the point of irrationality or harm.

Egregore comes from the Greek word ἐγρήγορoς ( egregoros ), meaning "watchful" or "awake."
