The Centurions of House Leo serve as medium ranked front-line officers, and actively participate in combat. Centurions are drawn from both military academies as well as from veterans and distinguished footmen. They are expected to lead by example on the battle front, leading the charge and rallying those under their command. Centurion ranks are of varying degree, junior Centurions command fewer men than Veteran Centurions. Juniors move forward in the military ladder by showing exceptional tactical sense or bravery in combat.

Centurions are easily distinguished on the frontlines, wearing large cloaks with a fur collar, as well as having an imposing plume on their head. Centurion armor is similar to footmen armor, but include a gold trimming and more heavily armored vambraces. They also feature more decorative features, such as an aiguillette and various medals adorning the belt. Some Veteran Centurions wear older variants of armor that are quite rare. The armaments of a Centurion include the standard sword and shield, but a spear is available if they prefer it over the sword. Etched on to their shield is "Semper Avanti", 'Always in the front' or 'Ever forward', referring to their dual duties as warrior and officer.
