Thanks to Alcott's advice, Kin and Gin's cooperation, and Arad's planning, the trip was taken at the right time for the flying fortress to be on the other side of the world, giving them an excuse to visit the Chromatic dragons first.
Because they were closer than the Metallic dragons, who went far away, of course, it won't be that easy or safe, and that is why Alcott was here.
Even with all of Arad's preparations, he still could only keep two Incarnations active for this trip. One had stayed with Tina, and the other would remain here in the castle because the two elvish queens need some care when Jasmine finishes dealing with the aftermath of the rebellion.
So for the time being, Arad was going to start moving. He jumped into the sky and transformed, waiting for Alcott to jump on his back and for everyone else to transform, but to his surprise, they all jumped on his back.
