The dragons came from the sky upon the call of Yuriel and Isaac.
Yuriel dragon was Aetonth, and Isaac was Icarus. That way, the dragon's abilities were just like their abilities, making things easy on the battlefield. Edward mounted on Icarus, too, and they travelled into Zimirt.
What should take more than one week now would be travelled in a single day, so Edward took advantage of those days to show the world to the boys.
They saw nothing but the ice mountains near the castle so far, making this the perfect chance to do what Kluster wouldn't. They fly the entire Kingdom seeing the most different things from the sky, it was good for the boys, but Edward was also expecting to see Gremory for some reason.
As if Gremory was going to see or feel them in the sky and come flying with his dragon to see their children, what didn't happen and was about time for the Derlvit.
