Bearkin

Bearkin have strong parental instincts and are willing to fight to protect their clans and families. To a Bearkin blood is thicker than water, and few situations would result in a Bearkin abandoning their clan and joining a life of adventure. Powerful and protective they tend to be wary of outsiders but make very loyal allies, though they rarely side with large kingdoms or armies due to their disinterest in politics.
As strong in heart as in physical ability, Bearkin are expected to provide and care tor their children (known as 'cubs') as best they can.
Blood Ties A traditional Bearkn tribe consists of one alpha male, the strongest, most capable leader.  Each Alpha has a single Beta, who is the next in the clans hierarchy, and is tied as second-in-command with the alpha's wife.
Under their command is several families of bearkin, whom swear loyality to the alpha until any of them deem themselves as strong enough to challenge the alpha in unarmed combat. If successful, the challenger becomes the leader of the clan, if they fail...they are likely cast out to find their own way. Bearkin clans tend to have strong names like First Tooth, Bloody Roar, or Scar Paw. The names are usually represented by symbols carved into trees on the boarder of the Bearkin territory to warn away rival tribes and foolish adventurers.
Most Often, a Bearkin will leave the clan if they fail to defeat the Alpha in a challenge or their clan is lost in battle. Less often the Bearkin will be banished for disgracing their family in battle or breaking the Bearkin law.
