You have the power to, at will, exude a terrifying aura, which channels your own ill feelings and hate and imposes it on people around you.
The scale of its effects depends on how strong you are relative to the people exposed to it, as well as their willpower. It can vary from them getting a chill running down their spines, wetting themselves or losing control of their bowels, passing out in terror, and in some extreme cases, can even kill them with a heart attack.
