A Clock Mechanism for measuring time.

"Time was the one inescapable constant, in all things. Even the mighty god-warriors were not immune to its passage… though they were revered above all others in Shuriman culture."
Zilean Zilean, The Chronokeeper

This article compiles all the official sources published by Riot Games into a non-exhaustive timeline of recorded important events in the League of Legends icon.png League of Legends linkRuneterra Prime (Universe) Runeterra Prime universe. This should not be considered as an official timeline but should be as accurate as, and more complete than, any timeline that Riot Games currently has provided.


Numbering in this Timeline is based on the founding of Noxus Crest icon.png Noxus (BN - Before Noxus; AN - After Noxus), as this is the method used by the official sources. All dates are considered to be spans of time from one to the next since many events are only given vague ordering and estimated dates.

With territories spread across Runeterra, the empire of Noxus Crest icon.png Noxus has united and assimilated countless smaller nations over the course of centuries. Aside from its obvious military strength and stable, central governance, Noxus takes great pride in "bringing the calendar" to every corner of the globe.

But to be Noxian is to subscribe to their notion of world's history, which begins long before the Rune Wars that gave rise to the empire. Since many historical records were lost in those dark times, the precise details of anything earlier are likely based on conjecture, or popular myth.


For easier navigation, the Timeline is split into several key historical events:


  • The first official timeline was revealed in the Realms of Runeterra encyclopedia book and formed the foundation for this Unofficial Timeline.
  • The concept of time travel being canonized in the main League of Legends lore has created a canon omniverse bearing infinite possible timelines.
