Commonality

The Commonality was a psycho-dimensional web which formed a matrix of shared energy that connected the psyches. Individual manifested themselves as blue orbs with blue linking lines of energy being the ties that binded the species together. Each member of the species acted as a transmitter that broadcasted its thoughts into the Commonality and thus was capable of being isolated and severed through technological means. Those that faced such an act were ripped from the unifying presence of the Commonality and devolved into an Atavus (lost rational mind and become angry).
