Hydaelyn literally tells us that Zodiark is bound on the Moon, that she sundered the star, that it was split across 10 and 3 each possessed of a shard and a part of Zodiark, that the Ascians want to tear down the barriers between these shards and merge them, creating a calamity/rejoining and that this has happened 7 times. Yet lacking the context we have now this was incomprehensible in 3.2 and all you could take from it was "Ascians = bad guys".
