When Elementalist Lux comes out, will Lux herself get some new lore?

I doubt it,they will likely add a lore for elementalist lux,but not for regular lux.

She will likely receive a new lore when they update the lores of all demacian champions.

Yes, I hope so. Will gain more interest for the champion and in so doing gain more interest for her skins and in so doing Riot gets munz, everyone wins.

I'm fairly certain that some Rioters said that her Elementalist story was in a separate world, like the Star Guardians. I'd double-check me on that first, though.

I'd love some new lore on Lux, though. She's one of my favorite champions.

There will likely be some kind of narrative for Elementalist Lux, but as for cannon lore, we likely have to wait until Demacia's turn comes around.
