Gather your hatred about you, and master it, my brothers. It is the strength behind your shield, the speed of your blade. Do not abandon it, for without it, you are empty indeed.
The Unyielding Rage
A tiny ampoule of steel and old, clotted blood, hung from a black iron chain, the Amulet of Dark Valor holds the drive of the furies.
In a city where the justice system features judicial dueling, plaintiffs and defendants are permitted to request a champion to take their place in the duel: Someone chosen by lot from among the foreigners in the city. When anyone first arrives, they are given an enchanted ceramic pendant that marks them as a candidate for "court duty".
Wealthy folk entering the city are often escorted by burly guards, paid to carry pendants on their behalf: They elude court duty in that way.
Adventurers may seek work as a rich man's proxy or may find themselves magically summoned to serve as a champion.
