People need to get it out of their head that all "dragons" need to come from Midgardsormr. This is factually incorrect.

Not alternate universes. Let's not parrot the theory of a youtuber. Besides, if what Solus has said is true, Hydaelyn is not the Mother Crystal and we can't trust what either of them have to say until we get the whole story. I hope that mount is the trial mounts for the expansion.
