Diplomatic Mishap

Meet with Karrok Stout-Hearted, the leader of the Glittering Wing tribe, and tell him about the tribal sign found on the Deadman's Rock.

Oh, I'm not sure at all! What if I falsely accuse the whites of allying with the Empire? They seem to value their words more than gold. Birds of honor, they are. If we make such a blunder, they won't even talk to us after that. Indeed, diplomacy isn't easy. Negotiating from a position of force was always more to my liking. You pull a sword, put it to the other party's throat and hand them your protest note. If your political opponent refuses to accept your note, you take a good swing and lay an embargo straight between their eyes. Oh, those were good times...
But never mind. Here's what I think. The aviak ruler owes you his life. Show him this emblem. If these birds really are plotting something, they won't touch you. A life for a life, that's how it works. And if they're not to blame, let them help us find the culprit, for it's in their best interest!

Quarr, friend. Why do you disturb me? I have already told you what I think about that piece of evidence. For now, I have nothing to tell you.

Where did you get that sign?! That's the sign of our sworn enemies, damned red traitors. They call themselves Steel Claw tribe! Long time ago, we were one tribe. But there were fools who wanted equal rights. A lady and a nest for everyone, and no need to work! They wanted a stupid thing, a revolution. There was the war, an old town was burned down. Now, there are two settlements, two tribes and a never-ending war.
Tell me why did you go to their settlement! You could not get the sign of Steel Claw anywhere else.
