Why not? Unarmored combat has been part of every culture in the world so why not Ravenland?But the fists talents remind me too much a monk from pathfinder/d&d, which doesn´t fit so well in the FBL setting.
Which works very well and is in spirit of the games design. There are also lots of good resources made by the communityWe play it open ended. Making up our own campaign as we play.
