The Ordo Spadino, also known as the Musketeers, actually predates the Ordo Gladio as a whole. Back when the lands of Aregrionno were far more dangerous, trained individuals would ride out and protect its people.

Only the most skilled with blade and crossbow are accepted into the order, regardless of birth or title. The musketeers primarily functioned as elite military assets and criminal investigators.

The Ordo Spadino was disbanded along with the Ordo Gladio in the leadup to the Aregrionno Civil War.
