Path of Thunder

A large sullen figure in heavy tattered robes sits in the shade corner of a tavern. A drunk patron antagoizes them, and soon regrets it when a thunderous crack sounds, and the figure's fist sends the patron flying, in a cascade of sparks. 

There are those barbarians that make no attempte to hide their short tempers, and then there are those that maintain a peaceful composure. A composure that is only betrayed by the storm in their eyes. Barbarians of the Path of Thunder are key examples of the kind of raw fury that a mortal is capable of containing. While out of combat they are still as stone, but those with enough insight can detect a distinct feeling of a distant force of nature. Should you be lucky enough to pick up on this, you would do well not to provoke the barbarian. This demeanor is how they exemplify the storm. Their calm presence is but a preamble before the storm.
