It's up to SE to make this one work. We don't have anywhere near enough info to say who it was if it wasn't Midgardsormr.
Did the Slyphs ever say that they had never summoned their Primal? could be that they made the decision to never summon their Primal after they had summoned him previously. Could be interesting if actually the Ala Mhigan's themselves summoned a Primal to oppose the empire sure would have bought them more time considering the empire halted its advance for 5 years. But yeah its too early to be sure of anything.
