The Adventurer's Society of Luthon is a free supplement for 7th Sea and Swashbuckling Adventures.
From the file's introduction
Founded in 1353, the Adventurer's Society of Luthon serves as a social club and sponsor program for men and women seeking to travel the exotic regions of Théah. While many look briefly at such a description and disregard the membership as a lesser version of the world-renowned Explorer's Society, the members of the Adventurer's Society point to their unique differences with pride. The club's age alone lends credibility to any denials of imitation. Like their more famous and expansive rivals, and countless other similar clubs in civilized cities throughout Théah, the Adventurer's Society serves as a rallying point for worldly individuals to share experience and knowledge in comfortable surroundings.
