Fishermen - mlichtenstein/13thAgeSK GitHub Wiki

A fisherman is one who captures fish or other aquatic creatures as a primary trade. Aquatic animals are a key source of food in most regions of the known surface world, so fishermen are quite widespread.

You wouldn't call them an ancient order of spies and assassins posing as simple fishermen, with traditions and secrets that predate all of recorded history. That sort of talk is dangerous.
