And how you know this exacly? The moogles very well know the dragons that are on the area, they would say that Nidhogg was responsable of all. Who said that Nidhogg destroyed the continent? I dont understand what you are ring to say
Yes, the devastation of the ruins on the churing mists is a clear sing that the dragons destroyed those structures with rage,

Kaiser was not saing anything related to the dragonsong war. I well agree with his that the moogles were refering to the 2nd umbral calamity ( if that is the calamity of fire of coruse )
