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

[Kesey]

All the more reason why it should be the hub city, then we procure their aid to confront this problem at the source in Islabard, where the towers are being produced.

But the towers are most likely everywhere and if they are to be used as the only evidence for 6.0 locations it puts Mercaydia, Thavnairia, Hingashi, Ivalice, Landis, Bozja, and Werlyt all back on the table, as well as expansions of old zones. But when you look at the towers as something that needs to be stopped, Sharlayan is the only area in the game that potentially hold the knowledge and the ability to stop the arcane nonsense the towers are spewing.
