6.0 Predictions: Will it be Garlemald, Sharlayan, or Meracydia?

[Kesey]

Not too long ago I solo-ed Gubal Library and Saint Mocianne's Arboretum to check stuff because Sharlayan architecture and patterns are suspiciously similar to those we find in Amaurot. More simplified, aye, but similar. I found particularly interesting that one of the rooms in Gubal is called the "Convocation House". Not an unique term, but after ShB I am eyeing everything with suspicion.

So I am not alone thinking they do know about the true story of the world and they are purposefully keeping it from being known. We do know that many fervent Hydaelyn believers come from Sharlayan as well, like Louisoix Leveilleur. And the Scions before the First shenanigans. We might be onto something there. Old Sharlayan is an island if I recall correctly, so perhaps it is a bit small for an expansion, but for a surprise final zone? It could be the case.

I was leaning toward Sharlayan being the new Crystarium or Kugane and the last zone of the expansion will be either an Allagn ruin (much like Ayzs Lla) but have a means to go to the moon (unless the moon is that final area, but I guess it could swing either way) ultimately to the final showdown with Zodiark. But I like your idea too.
