"Ah yes, those two. Those are the guardians of the realms. Your best view of them is from here, the center of this bridge. Nobody knows much about them besides that all of the snow birds and crow birds are descendants of them. When terrible things begin to happen, though, they ensure that they don't last for long. They're very large birds, and sometimes one or both of them will hang about one of the realms to eat or relax. It's rare to see one in a realm though, so we take it as a sign of good fortune. Any more questions, or shall we go forth?"
