The Empire generally takes a dim view on casual killings among its citizens. One exception to this is the Imperial Duel which is used among those of the noble Houses to settle matters of honor and prestige. In order to avoid problems with the Imperial Guard, a duel must conform to certain rigid standards, including the presence of a judge, seconds, witnesses, and a formal agreement between the parties as to how the outcome of the duel is to be decided (as not all duels are fought to the death).
