In principle, it could work. But since the Master mentioned an "eagle feather of incredible size," I'm afraid this isn't a very good fit. I'll look for something else now.

Forgotten Ghost has Kyiv in their profile -> the coat of arms of Kyiv depicts the Archangel Michael -> a feather of incredible size. It's not exactly an eagle feather, but it's similar.
Nah, I think what's depicted on the coat of arms of Kyiv is just a stretch, and it doesn't really have any special meaning.
But the eagle feather option: an eagle is a bird - a bird is the sky, and the sky is "Haven"))
I have this option as my main idea, so I vote for Olam Hável.
