Highdea: are MiMidgardsormr and his 7 children aliens?

Please don't let the Ascians have anything to do with Dragons, please, I beg you. I'm sick of dragons already.

I think that ship has sailed, Either with them manipulating events to set up the Calamity (Bahamut razing Eorzea) or with them teaching the Allags how to capture him (and having the Meracydian Horde summon him in the first place)
