So with the 2 champions missing in Mount Targon we have different options what could happen.
With the new Mount Targon event page i think i could list some of the possibilities on what could fill the 2 missing champion spots on the page. Just theories, i could be 100% wrong with every one of these and these two spots could even be for something else than champions.
a) Two new champions which i think is the most unlikely one, maybe only if the event lasts like 2/4 months.
b) A new champion and some other champion beeing reconnected to the lore, those two spots could really fit to the Taric rework (gem knight/protector/paladin similiar to Leona) and Aurelion Sol (dragon, named golden sun till yet - possibly has to do with the solari). Think about it, same happened to the Bilgewater event. A new champion to fit the lore (Illaoi) and champions beeing reconnected/reimagined (Gangplank)
c) Two champions beeing reconnected to the lore, this would be an interesting case altough most of the champions that need to be reconnected (except Taric) really don't fit Mount Targon (maybe only Skarner or Jax... but not really).
So what do you think is the most possible one and better - what do you expect from the event? Amazing lore? Making champions feel alive? Making the story feel alive? Reconnecting old champions and introducing new ones? Maybe even a new temporary map? Would really like to know what you think about it. I personally would like something like the Bilgewater event just because it told a amazing story and that even with visuals (looking at the old one armed Gangplank full of hatred, and some little VU's like Miss Fortune).
