[Agnes]

A broad term usually applied to the lowest forms of humanity out there: Orks, furries, feminists, college students, Tumblr users, Reptilians, and anime goddesses.
According to the Heresy Decree by the Law of the Imperial Truth, any members within these groups is automatically deemed [a heretic].
According to the [Codex] Astartes, All Heretics are to be purged instantly. If non-Heretics are found sheltering, befriending, or in any way expressing sympathy to [a Heretic], they are, themselves, Heretics, and are to be purged at once.
