Yeesh the Emet truthers are even more insistent than the Garlemald supporters back in the day...
Anyway there's two things i wanna throw out here and hope i have the braincells to return here to see people's responses about. Both these things deal with launch trailer content so spoilers:
On Fandaniel
It's weird to see so much discussion around Fandaniel's lines in the trailer because to me at least he sounds SO mocking. Like i can hear the bells of his little jester hat as he does a little dance while mocking everything the Ascians believed and worked for. I'm not a betting person but i'd bet that line is said to a fellow Ascian that didn't join him. This is based on the english version but having read french and german translations i think they sound super insincere too.
Final zone speculation
Ok so the trailer has this weird focus on going underwater and there's the line Emet says about going down to the place where souls and stars rest and the crystal dungeon that looks very much like the heart of the world... Guys. Guys i think we're FINALLY gonna find out what the entire hell is under Silvertear Lake and THAT is gonna be our final zone. I had never thought about the moon serving as a red herring but as a tinfoil enthusiast i'd also like to add that they made it clear from the first teaser we'd be going to the moon and if it was such a huge "spoiler" i don't think it would be advised like that.
