Some confusion about Ishgard?

[Xibri]

TL;DR In the trial Steps of Faith, I thought all the dragons attacked from the north end of the bridge between Ishgard and Gates of Judgement, but; Ishgard on the north end of the bridge is not under dragon control. So where did all the dragons come from?


I thought that when we're fighting the giant dragon on the bridge, in the trial The Steps of Faith , that all the dragons were coming from the other side of the bridge. What confuses me is the other side of the bridge is Ishgard and it's not dragon controlled. I had assumed that the land north of The Gates of Judgement, In Coerthas Central Highlands, was controlled by the dragons. I figured there would be a part in the story where Ishgard was liberated or something along those lines at the end of ARR or the start of HW. My best guess is that the dragons invaded by getting on the bridge in the center. Flying in from the sides, or above. Then they started marching towards The Gates of Judgement side of the bridge. If not then where did the dragons come from. If invasions of the dragons were coming from the north wouldn't Ishgard be the stopping point of such an invasion.Did this all happen on a different bridge than the one from The Gates of Judgement to Ishgard. If this was the case, I don't see why a large group of soldiers wasn't sent after the dragons from the Ishgard side to help. I'm just really confused.
