A Shadow is a type of Psy-Human that can hide a person from the perception of others. They are a defensive type of Psy-Human.
Psy-Humans can look like any different race and people. They don't have any features that sets them apart from normal people except that many Psy-Humans have heterochromia, or that is that both of their eyes are different colors.
A lot of Shadows are loners, who prefer to stay away from other people. They often have the "I don't need anyone else," or the "people only want to use me" attitude.
Shadows have the ability to hide people, objects, or themselves from normal perception. This ability can also be used to hide people from the sight of Detectors.
All Shadows can use the Psy-Network.
