I learned of the change to the Heran capital shortly after it was crystallized. It was fairly easy to see just from high ground near to what was the frontier then.

[He's sure he'd sent a letter about it, to all as well, back at that time. But Heroes came and went so he'd given up keeping a log of what he'd sent. Spencer would be able to tell him for sure, no doubt.]

I'm under the impression that often Esdham sends patrols via airship to monitor, but with all the other pulls on resources that have come up since then it wouldn't surprise me if it might have dropped in priority.

There are a few reports that were made, probably since filed in the archives, I should think.
