@Riot Opeli: Regarding Runeterra's lore, have you thought about copying Blazblue?
What do I mean by that? In the Blazblue franchise, time-based interventions (called phenomena interventions) are frequently used as a kind of "time rewind" whenever sh!t hits the fan, allowing a do-over that lets the story progress properly. I'm probably not explaining it well, so you can find info on it here:
http://blazblue.wikia.com/wiki/Phenomenon_Intervention (Some extra reading will probably be required)
Essentially, I was wondering if Riot's lore team had thought of utilizing a similar story element. Say, the Institute of War uses time magic to intervene whenever a Champion is killed outside the Fields of Justice, preventing things from getting out of hand. They can't quite expect them to be civil with each other all the time, now can they? It'd also explain why the lore seems to be in a perpetual limbo, where nothing really progresses (after all, you can't let Rengar kill Kha'Zix for real).
Interesting way to tell the story?
