What does Close to the sun in lonely lands mean?

Answer 1

That the Eagle is really high, so high that he is near the sun (hyperbole). No one has ever been so high, so it is lonely, or he is watching, ready to hunt, and eagles hunt alone I think, so he hunts alone from a high crag in a mountain.

Answer 2

This phrase likely conveys a sense of isolation or solitude, as being close to the sun in lonely lands implies being removed from others in a remote or desolate location. The imagery suggests a person or entity that is isolated, exposed, or experiencing intense heat or scrutiny in an empty, unforgiving environment.
