Although I assume that the Dominion have an organisation equivalent to the Free Companies of Nexus I feel those organisations are more tied to the Paths (like Scientists will be members of the Exile Academy of Science [XAS] or the Dominion's Collegium) so the name would have to be a generic reflection of the combat style rather than denote a position (you could just be some buy who picked up a sword!). Warrior does get to the point but is perhaps a little too fantasy-themed. Hmmm... I can see the point so let's see what my mind comes up with. Blademaster Swordsman Blade/Sword Marshal (named for William the Marshal) Deathblade Bladeweaver Nothing else really comes to mind right now!
