Sergeant
The Sargeantry is a uniquely An Tirian tradition. It was begun when An Tir was a principality and a long, long way from the Crown. Candidates for sargentry were tested in all the skills of knighthood: arts, sciences, warfare, courtly manners, dancing, and more. When the Crown did come to An Tir, we could assure him that these find gentles were worthy of consideration.
They are in generally direct fealty to the Baroness of the branch that they tested for. Although some Baronies have them in featly to both the Baron and Baroness, and others have select categories (eg Courtier) in fealty to the Baron.
Though originally created to recognize and encourage heavy fighting, Baronesses have expanded their sargentry to include other martial and non-martials skills.
