The Totem of Nehual is something of a Maltese Falcon. Many have spent long periods of their life searching for it, spending vast sums of money, and in the end never finding it, or only finding it long enough to lose it.
The massive blade known as Consequences carries several potent enchantments of battle, but also has a frustrating quirk: Its wielder finds himself unable to put it down until he enters the presence of a magistrate or other authority. Even then, it instantly returns to his hands if he has committed murder and fails to confess. Unless he somehow resists the blade's magic, the weilder's hands then run with fresh blood; the judgmental blade fights his every motion until he confesses his crimes.
