The Fields of Justice are areas in which champions battle against one another in order to achieve victory.
|"You belong in a museum!"
The League resolved that all major political conflict would be settled through the use of specially prepared arenas strategically located throughout Valoran. Summoners representing a particular political allegiance would each call forth a champion; the champions, leading mindless minions generated by novice summoners manipulating a Nexus, would fight to achieve the objective of the arena they were in. The most common victory condition of a battle arena would be to destroy the opposing faction’s Nexus. These arenas are collectively referred to as "The Fields of Justice".
The fights in the various Fields of Justice over which the League presides are not only of great political interest to Valoran, but also of great social interest. The League magically transmits the sights and sounds of the action as it unfolds to specially built arcane receivers located in key settlements throughout Valoran. Watching a fight in a Field of Justice is one of the more popular entertainment activities Valoran's denizens engage in.
