New continents/races is a given as they’ve told us the map we have is only a fraction of the planet.

I figure if there is a void event they wouldn’t seal it or banish it, it’d be more like “we sealed off a couple of entrances, woohoo!” Also it’d be another “Avengers superhero team up” like the ruination was.

Same for LeBlanc Vs Morde, avengers team up.

I’m pretty sure the other gauntlet to Ezreal’s is Kassadin’s blade. Correct me if I’m wrong or the lore changed.

I could see them retconning Shaco(and Nocturne) to officially be a demon in order to save time and mental instead of working with his current lore.

Similarly I can see Riot destroying Ixtal in order to not have to waste anymore time developing it.

Highly doubt they’d kill off a champion but they technically already killed Aatrox before. If anything they’d seal him in some type of way.
