Empties are also called blanks, dreamers, pacifists, and downers. They are an unfortunately common sight.
The same mental remnants that cause casualties to gather in locations that they frequently in life goes haywire in an Empty. They do not bite, hunt or attack. They simply repeat an action over and over, stuck in an endless loop, mirroring an action they performed in life. Sitting in a living room, watching a blank television screen, scrolling on a long dead phone, with baseball glove in hand, waiting for a pitch that will never come. Somehow, these casualties are more haunting than the ones ripping your teammates apart. They are a reminder of the humanity lost and how the creatures you are gunning down may have been your neighbor or family days before.
