The Warbringer's Son

From the publisher:

For years, the Bandit Lord has ground the countryside under his heel, crippling your people with his cruel demands. The time has come to end his bitter reign. Armed with naught but your courage, you will put an end to his tyranny or die trying. But the Bandit King himself is only a pawn answering to Kainos, the Warbringer's Son, a half-god intent on setting the North aflame with conflict, and slaughtering all that stand in his way.
The Fifth Annual Gen Con Open Tournament, The Warbringer's Son was one of the bloodiest tournaments on record. Many have tested their might against the Warbringer, and many have fallen. How will you fare?
