"If you can path to a territory as in Reave and there is a character present (defending, attacking, etc) in this province then you may battle them in single combat.  This means getting higher than their total contribution to the battle.  Regardless of which side wins the battle, you take them as your prisoner unless they make a Hard (16) Warefare roll to escape.  You gain one of their items randomly and take possession of them as your captive."<br/><br/>You join the battle like any other combatant minus the chance of being captured yourself.
