Judges travel all around the world, visiting small towns and villages that do not have an established legal system. Petitioners can bring complaints before them and request a hearing. After the hearing, the Judge decides whether or not to call witnesses, and then delivers an arbitration, enforcable by local military or guards.
Most of the Judges are Half-Elves. This is because their elven parentage gives them a mind for fairness, with their human side tempering the aloofness Elves are prone to.
