Paraphrased Lore: League of Legends

Map of Valoran

On the planet Runeterra, there is a Pangaea-like continent known as Valoran, where there exists an organization dedicated to the mediation of political conflicts; The League of Legends.

The reason this organization was created relates to the history of warfare on this planet. Just as atomic weapons unleashed pillars of nuclear flame on Earth, so did raw magical powers devastate the geophysical landscape of Valoran. The rampant use of arcane and powerful magics, wielded by the feuding tribes of ancient Runeterra, lead to a series of conflicts known as The Rune Wars, where entire armies were reputed to have been disintegrated by the power of spell-craft alone.

Champions of these conflicts were granted great relics of power, and summoners, also regarded as de facto leaders for Valoran's political forces, were responsible for requisitioning all available magical might.

As magical warfare decimated the landscape, life on Valoran degraded, and it quickly became apparent that alternate forms of warfare were necessary. Evidence of this could be seen when it appeared that another Rune War would destroy Runeterra altogether.

Warfare needed to be controllable and systematic, the politicians of Valoran concluded, and it was this line of thinking that lead to the creation of the League of Legends. Negotiations between Valoran's key magicians, including many powerful summoners, lead to the creation of The Institute of War, a facility whose sole purpose was to enable the resolution of conflicts in a controlled environment.

The Institute of War

As the Institute neared completion, the governing political bodies of Valoran carefully selected fields upon which these conflict resolutions would take place, inasmuch three selections were made; Summoner's Rift, The Twisted Treeline, and The Crystal Scar. After these areas had been prepared, it was up to the masses to select the best, most capable combatants among them, for it was the responsibility of these combatants to represent their respective political faction.

Noxus

Among the participants, those of Demacia and Noxus presented the most bitter of rivalry. Noxus, considered to be the moral antithesis of Demacia, welcomed the creation of the League of Legends, and even was supportive of it. With regard to the cost of warfare, it was determined that the League offered a far cheaper alternative, so that the Noxian High Command might better direct their efforts to off-shore conquests...
