From the introduction:
Greetings, and welcome to Runeterra- The world of the League of Legends. Far from a perfect place, Runeterra is a place torn by war and political strife. To remedy this, a council was created as an intermediary, an arbiter of conflict on the continent of Valoran- The Institute of War. The Institute proposed a system where each nation would offer up Champions to fight in 5 vs 5 matches against one another, with powerful magical Nexuses keeping them from ever truly dying. The goal would be to destroy the opposing nexus, and each Champion was paired with a Summoner to direct them, help them in battle, and see where the Champion could not. Soon, a sport of battle was created, and the Institute of War became the home of the League of Legends- A collection of the world's most powerful men, women, and yordles vying for supremacy on the battlefield known as Summoner's Rift.
