Antaurus and Limia League of Warriors
The League is a well organised and well promoted fighters guild with representation across much of the western stretches of the Former Empire. It seems to attract reliable fighters who have no interest in formal military skills. The guild has built a good reputation for itself by providing high quality training for its members, and investing heavily in its facilities.
The guild has standard membership available for 120gp per year, and fellowship membership (from 9th level) for 220gp per year.
