A Fayber is the term applied to a member of American Motorized Combat League (AMCL) who partakes in any activities other than AMCL Exhibition, raiding, defense, and mercenary work. The culture of the League is very cynical, so anyone who takes feuds or ethics seriously is the target of some sneering.
This does not include the routine Kayfabe required as part of the job of League Exhibitions. It is understood that all participants to a degree take part in theatrics.
