A compulsion is a deeply held belief or motivation which is so strong it overrides conscious control. It is internal, and may not have any obvious rational cause or source. It manifests as uncontrolled behavior that can place the character in peril physically or socially.
The victim is fascinated by a particular object, place, person, circumstance, or event; to the point that they are compelled to promote the circumstances which place themselves to witness or act on it – even if their survival is imperiled by it. The compulsion may be resisted with a Sanity check. A character can automatically violate the compulsion in an encounter to achieve some end without making a resistance check, automatically suffering from Disorienting Anxiety (guilt, self-doubt, and shame) immediately afterwards.
