Initiatus, or "The Initiated" is a network of Libre Fighting practitioners who have officially been accepted into the Libre Fighting organization. Membership cannot be bought and there are no dues. Perspective members must be sponsored by a Chapter Head and undergo a period of apprenticeship before being inducted. Members of The Initiated span the globe. 

There are no martial arts style ranks within Libre Fighting. Rather, The Initiated progress through a hierarchy and are awarded various symbolic tokens as recognition of their position within the structure.
