League of Legends の舞台はField of Justiceと呼ばれる。



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.


ヴァロランの魔術師達は、世界の物理的、政治的不安の対応策として「紛争をコントロールするためにシステム化された方法で解決する必要がある」という結論を出した。そこで彼らは、ヴァロランにおける紛争などを監督することを目的とする"League of Legends"という組織を設立した。

League of Legendsはヴァロランの全ての政治的衝突はヴァロラン各地に用意されたバトルアリーナを用いて解決しなければならないと決議した。そこで各地のサモナー達はバトルアリーナで戦うためのチャンピオンを召喚しはじめ、未熟なサモナーが召喚した心のないミニオンを率い、目的を達するために戦いを始めた。これらのアリーナをField of Justiceと呼ぶ。

League of Legendsが指揮するField of Justiceの戦いは、ヴァロランの住人の多くが政治的および社会的な関心を持ち、住人たちもっとも人気な娯楽にもなっている。戦闘の様子は魔法により転送されヴァロラン各地の主要都市の受信機に転送されることで、見ることができる。



  • The Butcher's Bridge - Once an ancient stone bridge leading to a temple entrance, it’s been kept up haphazardly and primarily serves now as a connection between the slaughter docks and one of Bilgewater’s slums.
  • 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 Howling Abyss - The Howling Abyss is a bottomless crevasse located in the coldest, cruelest, part of the Freljord. Legends say that, long ago, a great battle took place here on the narrow bridge spanning the chasm. No one remembers who fought here, or why, but it is said that if you listen carefully to the wind you can still hear the cries of the vanquished tossed howling into the Abyss.
  • 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 - Deep in the Shadow Isles lies a ruined city shattered by magical disaster. Those who venture inside the ruins and wander through the Twisted Treeline seldom return, but those who do tell tales of horrific creatures and the vengeful dead.
