The Field of Justice (or Map) is the arena in which the champions battle against one another in order to achieve victory.

Lore

As a direct response to the world’s growing physical and political instability, Valoran’s key magicians – including many powerful summoners – came to the conclusion that conflicts needed to be resolved in a controllable and systemic way. They formed an organization called the League of Legends, whose purpose was to oversee the orderly resolution of political conflict in Valoran. Housed in the Institute of War, the League would be given the authority by Valoran’s political entities to govern the outcomes of the organized conflict they would administer.

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.

The Fields

• The Crystal Scar - The Crystal Scar was once known as the mining village of Kalamanda, until open war between Demacia and Noxus broke out over control of its vast underground riches. Settle your disputes on this Field of Justice by working with your allies to seize capture points and declare dominion over your enemies!
• The Proving Grounds - A narrow bridge situated over a vast howling chasm marks the battlefield known as The Proving Grounds. Legends are told of small bands of valiant warriors holding off entire armies at this point. To this day, the bridge remains a key strategic position in times of war.
• The Summoner's Rift - The oldest and most venerated Field of Justice is known as The Summoner’s Rift. This battleground is known for the constant conflicts fought between two opposing groups of Summoners. Traverse down one of three different paths in order to attack your enemy at their weakest point. Work with your allies to siege the enemy base and destroy their Nexus!
• The Twisted Treeline - Twisted Treeline is one of the few remaining forests near Zaun that has not been exploited for natural resources; a mere cursory glance at the geography of the area quickly explains why. The misuse of magic – mainly from Zaun but also from the numerous battles fought here during the various Rune Wars – has warped the verdant environs of the Twisted Treeline terrain into a bizarre, alien-like visage.
